🪛 FIXRemoved the DXGI presentation-forcing block (12 DXGI_* keys under HKLM\SOFTWARE\Microsoft\DirectX) from SYSTEM_TWEAKS.PS1 — undocumented tweak-pack values the system does not read (frame latency is a per-process API: IDXGIDevice1::SetMaximumFrameLatency).
🪛 FIXRemoved Scheduler\ForceIndependentFlip, Scheduler\QueuedPresentLimit and GraphicsDrivers\MaxFrameLatency (incl. the "MaxFrameLatency " trailing-space duplicate) from SYSTEM_TWEAKS.PS1 — forced independent flip with a 1-frame queue made the present path wait inside the DPC on missed VSync deadlines. Flip queue is left to the driver/DWM default.
🪛 FIXRemoved HwSchMode/HwSchTreatExperimentalAsStable writes from SYSTEM_TWEAKS.PS1 — the script was re-enabling HAGS on every install, contradicting the "HAGS managed by GPUTweaks tri-state" decision. HAGS state is now owned exclusively by GPUTweaks (DEFAULT/ON/OFF). HwSchedMode (misspelled inert variant) purged.
✨ IMPROVEMENTDEVICES-TWEAKER-AUTO.PS1: interrupt spreading now covers every device class (community fix LTT). Storage (NVMe) devices are no longer excluded from assignment; wired NICs receive an explicit SpecCPU affinity (WiFi stays excluded — affinity breaks many WiFi drivers); DevicePolicy + AssignmentSetOverride are written for all assigned devices, not just non-NET.
✨ IMPROVEMENTDEVICES-TWEAKER-AUTO.PS1: new PHASE 7 locks interrupt routing (power setting "Interrupt Steering Mode" = 4) on the active power plan (AC+DC) via powercfg, so Windows dynamic steering can no longer override the static SpecCPU affinities. New -SkipLock switch to opt out.
✨ IMPROVEMENTDEVICES-TWEAKER-AUTO.PS1: writes RmForceEnableMSI=1 under HKLM\SYSTEM\CurrentControlSet\Services\nvlddmkm\Global\NVTweak when an NVIDIA discrete GPU is detected — the GPU affinity block is a no-op without active MSI (Blackwell-class hardware stays on legacy INTx and ignores the pinned affinity); the internal NVIDIA RM key (verified read by the driver, per GPUTweaks source) switches the GPU to MSI so the SpecCPU affinity is honoured.
🪛 FIXRegistry hygiene: obsolete GPUTweaks "DPC/ISR Latency" residues (SchedulingDelay, RmGpsPsEnablePerCpuCoreDpc, DisableWriteCombining, PrimaryPushBufferSize, RMDisablePostL2Compression, D3PCLatency, FlTransitionLatency, MonitorLatencyTolerance=1000, RMDeepLlEntryLatencyUsec, RmDisableRegistryCaching, NumberOfIdleStates, PowerSavingTweaks, UseGpuTimer, RuntimePowerManagement/PoFx*, LogicalAddressMode, PreferHighLogicalAddresses, Protection*, TdrDebugMode/TdrLimitTime/TdrLimitCount/TdrTestMode, HwSchPriority, GpuPreference) purged — removed from scripts long ago but never deleted from the registry by upgrades. Playbook updates must purge retired values, not just stop writing them.
🪛 FIXMMCSS: Pro Audio and NIC scheduling reverted to pre-change state in FINALIZE2.CMD and MMCSS-NIC.PS1 (Pro Audio Medium, SchedulingPeriod 10000) — the earlier High / SchedulerPeriod changes were not justified.
✨ IMPROVEMENTKnown residual (not playbook-related): intermittent nvlddmkm DPC peaks >1 ms — documented NVIDIA driver behaviour on Blackwell-class hardware (driver 596.49).
✨ IMPROVEMENTNVIDIA HDMI audio codec disabled on the test bench (unused — audio output is USB); NVDisplay.ContainerLocalSystem kept enabled (required for the NVIDIA Control Panel) — the GPUTweaks "Disable NVIDIA Services" tweak is the opt-in to disable it.
✨ IMPROVEMENTPower plans restructured: playbook now detects CPU architecture on install. **Intel** -> deploys `LexBoosT_Ultimate_For_FPS(INTEL)_Hybrid.pow`. **AMD** -> deploys `LexBoosT_Ultimate_For_FPS(AMD)_Hybrid.pow`. Each hybrid plan combines the FPS-optimised CPU base (core unparking, heterogeneous scheduling) with Kizzimo-derived low-latency settings (Interrupt Steering, NVMe/disk timeouts, PCIe ASPM off, USB selective suspend off, sleep/idle transitions minimal). Ensures both max FPS and near-minimal DPC latency in a single plan.
✨ IMPROVEMENTStandard FPS plan (`Intel` or `AMD` variant, detected automatically) and Latency plan (`INTELAMD`) are also imported but **not activated** — both appear in Power Options for manual selection alongside the active Hybrid plan.
✨ IMPROVEMENTRemoved generic `LexBoosT_Ultimate.pow` — replaced by CPU-specific plans.
🪛 FIXMerged EDGE.PS1 + RemoveEdge.ps1 into single unified EDGE.PS1 with 5 modes (EdgeBrowser, EdgeUpdate, Full, Install, WebView2). Multi-method uninstall (4 retry strategies) from RemoveEdge.ps1 merged into EDGE.PS1. RemoveEdge.ps1 replaced by thin wrapper delegating to EDGE.PS1.
🪛 FIXRemoved orphaned scripts, duplicate task calls, stale references (security.yml, NETWORK-EXTRAS.PS1, SYSTEM_TWEAKS.PS1, L2L3.PS1, FIND-NETWORK-ADAPTER-PATH.CMD, PRIVILEGED-REGISTRY-TWEAKS.CMD, TELEMETRY_CHECK.PS1).
🪛 FIXRemoved dead variables/functions across multiple PS1 files. Moved Set-UserFolderIcon before Add-Type to prevent TrustedInstaller crash.
🪛 FIXRemoved 4 redundant zero-value memory keys from FINALIZE2.CMD. Simplified security.yml to only what DENY-CONSENTSTOREPERMISSIONS.PS1 doesn't cover.
💥 BREAKINGRemoving Testing powerplan folder.
✨ IMPROVEMENTAdded DXGI tweaks (12 keys — ForceFlipDiscard, MaxFrameLatency, DisableDwmThrottling, FullscreenFlipMode, PreemptionMode, SwapChain optimizations) for reduced DirectX presentation latency.
✨ IMPROVEMENTAdded GraphicsDrivers scheduling/DMM/Power tweaks (ForceIndependentFlip, QueuedPresentLimit, EnableGpuBoost, ModeListCaching, VirtualRefreshRate, link timeouts, DevicePowerRequired) for lower GPU scheduling overhead and display management.
✨ IMPROVEMENTAdded TdrDelay=20 under dxgkrnl for stable GPU timeout handling.
✨ IMPROVEMENTAdded BackgroundPriority=0 to Games MMCSS profile for consistent background task priority.
✨ IMPROVEMENTAdded Microsoft Games Optimization FPS overlay (FpsStatusGamesAll, FpsStatusGames, FpsAll, GameFluidity).
✨ IMPROVEMENTMMCSS: Recalibrated NIC profile (SystemResponsiveness=0, NoLazyMode=1, NetworkThrottlingIndex=4294967295). Added Games profile (GPU Priority=8, Scheduling=High, Latency Sensitive) and Pro Audio profile for low-latency audio scheduling.
✨ IMPROVEMENTAligned DWM parameters with external performance tweak pack — reduced compositor latency, lower GPU overhead.
✨ IMPROVEMENTAdded kernel/DPC/interrupt optimizations, DirectX throughput tweaks, and system-wide resource policy boosting for consistent foreground performance.
✨ IMPROVEMENTAdded power-limiter registry overrides (CPPC, ASPM, package idle, energy telemetry) to minimise background CPU throttling and PCIe latency.
🪛 FIXRemoved dead kernel values in SYSTEM_TWEAKS.PS1 (BufferSize, IoQueueWorkItem x7, XMMIZeroingEnable, UseNormalStack, UseNewEaBuffering, StackSubSystemStackSize, TimeSlip, EnableGpuBoost, ProcessDCEsInUseThreshold, HwSchPriority, GpuPreference, Capabilities, IoPageLockLimit, FeatureSettings) - kernel API names or obsolete values never read by the kernel (the documented KB4073119 pair FeatureSettingsOverride/Mask is kept). Win32CalloutWatchdogBugcheckEnabled 1->0 (default; avoids BSOD on stuck Win32 callouts). SystemResponsiveness 0->10 in MMCSS-NIC.PS1 (values below 10 are clamped to 20 by the kernel).
🪛 FIXScript fixes: DISABLE-HIDDEVICEWAKE.PS1 now language-independent (powercfg -devicequery wake_armed loop - hardcoded localized names were a silent no-op); SOFTWARE.PS1 global %TEMP% purge replaced by targeted installer cleanup; APPLYDUHIVE.PS1 YAML parsing fixed (was collecting 0 paths), value types preserved (DWORDs were re-created as REG_SZ), task now runs as the current user (HKCU was SYSTEM's empty hive); APPX-REMOVER.PS1 runs full mode (registry/file cleanup was dead code under -AppxOnly); EDGE.PS1 Remove-IEPackage queries the package dynamically (hardcoded build no-oped on 24H2/25H2); DISABLE-DEVICE-POWER-SAVING.PS1 now writes the values under Device Parameters (previously never written); CROSSDEVICERESUME.CMD permanent kill-task replaced by a one-shot kill.
🪛 FIXMinor fixes: BACKUP.PS1 control-char regex corrected; DEPLOY-ROLLBACKSCRIPT.PS1 uses $PSScriptRoot; DEL_WINOLD no longer deletes PerfLogs; FILE_ASSOCIATIONS FriendlyTypeName "Fichier VBScript"->"VBScript File"; APPX-REMOVER removed nonexistent aumall process; LOW-LATENCY-PROFILE log aligned to the 3 enabled feature IDs; CLEANUP-ACTIVE-SETUP removed dead StubPath write; CLEARCLASSFILTERS removed unused setlocal.
🪛 FIXAccessibility/keyboard: all Flags converted to REG_SZ (Control Panel canonical type); removed selfscan/selfvoice, empty MaximumSpeed/TimeToMaximumSpeed, Last-* FilterKeys residues, and the Warning Sounds/Sound on Activation=0 writes (owned by AUDIO.PS1=1). StickyKeys 506 kept.
🪛 FIXExplorer: unified conflicting values on explorer.yml - ShowStatusBar, TaskbarSn, ConvertibleSlateModePromptPreference -> 0 (HKCU + .DEFAULT); SEARCH.PS1 TaskbarSn aligned to 0. AutoEndTasks=1/HungAppTimeout=1000 kept deliberately (auto-kill hung apps; decision documented in code). UserPreferencesMask completed to 8 bytes (90 12 03 81 10 00 00 00).
🪛 FIXPolicy hives corrected: DisablePCA and AITEnable moved HKCU->HKLM (machine-scope policies were inert in HKCU); IE SQM value renamed to DisableCustomerImprovementProgram and set to 1 (was 0 = CEIP active), HKCU copy added; WER LoggingDisabled added in HKCU alongside HKLM.
🪛 FIXMiscellaneous fixes: Accesibility->Accessibility typo (4 dead keys); MessagingSvc->MessagingService (silent failure); NoAutorebootWithLoggedOnUser moved to the correct WindowsUpdate\AU path; wevtutil /q:false->/e:false (Sleep Study channels); DiagLog/WdiContextLog autologgers aligned to 0; phantom AutoLogger-Diagtrack-Listener renamed to Diagtrack-Listener; PreventHandwritingData->PreventHandwritingErrorReports; VS SQM OptIn=0 extended to VSCommon 14.0-17.0; Windows Defender duplicate ScheduleDay removed.
🪛 FIXMouse latency: RawMouseThrottleEnabled 1->0 (disables raw-input throttling); removed SmoothMouseXCurve/YCurve deletion (OPTIMIZE-MOUSESMOOTHINGCURVES.PS1 is the single owner of the curves).
🪛 FIXServices: AppMgmt, MSDTC, MapsBroker, SEMgrSvc, WalletService, WMPNetworkSvc, SSDPSRV kept disabled (Start=4) deliberately - none of their features are needed on a gaming desktop; trade-offs documented in services.yml (re-enable SSDPSRV if DLNA / network discovery is ever needed).
🪛 FIXMMCSS SystemProfile: MaxThreadsTotal 0->65535 and MaxThreadsPerProcess 0->128 (out-of-range 0 was clamped to the minimum, enforcing the strictest thread limits).
🪛 FIXGlobalTimerResolutionRequests moved to the correct Session Manager\kernel path (read at boot; effective on Windows 11+/Server 2022+; complements TimerControl). Reverses the earlier decision that marked the kernel path as wrong.
🪛 FIXGPU/DWM/audio/disk fixes: HwSchedMode->HwSchMode; CreateGdiPrimaryOnSlaveGPU moved to Control\GraphicsDrivers; TdrLevel=3 + TdrDdiDelay=10 restored; InkGPUAccelOverrideVendorWhitelist REG_SZ->REG_DWORD; DisableStartupSound 0->1 (was re-enabling the startup sound); NtfsDisableCompression aligned with fsutil; CrashControl aligned with CEIP.PS1; MMCSS GPU Priority=8 and Pro Audio High aligned across all files.
🪛 FIXKernel/network/power fixes: SchedulingPeriod->SchedulerPeriod (50000); DpcTimeout->DPCTimeout and MaximumDpcQueueDepth->DpcQueueDepth; TdrDelay moved to Control\GraphicsDrivers; hibernation stays enabled on desktop (removed conflicting 0 writes - CUDA/TensorRT requires hiberfil); SerializeTimerExpiration aligned to 1; stornvme IdlePowerMode deterministic (0 desktop / 1 laptop); netsh timestamps/uro aligned (timestamps=disabled, uro=enabled); MMCSS Pro Audio category High; Games BackgroundPriority 1.
🪛 FIXRegistry robustness: replaced hardcoded ControlSet001 with CurrentControlSet (symbolic link to the active control set - tweaks survive boots from an alternate control set). Completes the WMI Autologger migration. Thanks j1m for the info.
🪛 FIXIRQ authority: DEVICES.PS1 no longer runs Configure-IRQAffinity/IRQPriority (DEVICES-TWEAKER-AUTO is the single authority, it runs after and was overwriting those writes); DEVICES-TWEAKER-AUTO runs with -SkipImod (no winio.sys kernel driver / raw MMIO writes to xHCI IMOD registers).
🪛 FIXDEVICES.PS1: TdrLevel 0->3, added TdrDelay=8s/TdrDdiDelay=10s. Fixes black screen + max fan spikes. Removed aggressive watchdog overrides + idle-state limits.
🪛 FIXSYSTEM_TWEAKS.PS1: Removed duplicate watchdog overrides matching DEVICES.PS1.
🪛 FIXservices.yml: GpuEnergyDrv and GraphicsPerfSvc from Disabled->Manual. Fixes GPU fan stuck-at-max and broken real-time scheduling.
🪛 FIXTELEMETRY.PS1: Removed duplicate DmaRemappingCompatible sweep (already in DEVICES.PS1).
🪛 FIXFINALIZE2.CMD: Reinforced touch/touchpad/touchscreen guard with two-layer detection (chassis type + PnP I2C HID scan). Now correctly identifies MSI laptop I2C HID touchpads (ELAN/Synaptics/ALPS) and skips touch/tablet tweaks on any portable chassis. Removed dangerous writes (TouchGate, EnableVirtualTouchpad, EnableTouch, Synaptics tap actions) that could disable HID/I2C pointing devices.
🪛 FIXTouchPadSyncDataAvailable task: Changed from `desktop-only` to dedicated opt-in checkbox `disable-touchpad-sync`, unchecked by default. No longer bundled with desktop-only.
🪛 FIXDELETE_OLD_DRIVERS.PS1: Now opt-in via `delete-old-drivers` checkbox, unchecked by default. Added protection filters that skip driver removal for critical device classes (HIDClass, System, Mouse, Keyboard, Display, audio, ACPI, Firmware) and OEM providers (Intel, AMD, Realtek, Synaptics, ELAN, NVIDIA, Microsoft). Prevents pnputil /delete-driver from breaking I2C/SerialIO/ACPI/chipset driver stacks on OEM laptops.
🪛 FIXSYSTEM_TWEAKS.PS1: Removed HwSchMode from playbook (managed by GPUTweaks HAGS tri-state).
✨ IMPROVEMENTGPUTweaks: Removed 5 duplicate registry entries across NVIDIA tweaks — ShaderCacheMode, RMEnableASPMPublicBits and HwSchMode from Low Latency Tweaks (kept in Graphics Drivers Tweaks / HAGS Mode); EnableHDAudioD3Cold and UseDpcForGpuWatchdogCallback from DPC/ISR Latency (kept in Disable HD Audio D3 Cold / nvlddmkm Tweaks). Zero redundancy.
✨ IMPROVEMENTGPUTweaks: Added optimization profiles (ComboBox) — Performance (max perf, all tweaks applied), Balanced (safe subset), Quiet (power efficient), Custom (manual). Selecting a profile auto-applies/reverts tweaks. Manual toggle of any tweak switches to Custom without affecting others. Added Revert All button.
🪛 FIXGPUTweaks: Fixed state persistence — LoadState now propagates IsApplied from JSON backup to State, showing correct button immediately on startup. Scan no longer overwrites a persisted "applied" state (JSON backup is source of truth).
🪛 FIXGPUTweaks: Fixed dark ComboBox theme (custom ControlTemplate with ToggleButton, matching dropdown width to control width, no crash on click).
✨ IMPROVEMENTGPUTweaks: Added latency-reducing nvlddmkm tweaks to nvlddmkm Tweaks (RmForceEnableMSI=1, RmDisableDmaRemapping=1).
✨ IMPROVEMENTGPUTweaks: Extended Low Latency Tweaks with PowerMizerEnable=0, PerfLevelSrc=0x2222, ForceMaxPCIeSpeed=1 for maximum GPU perf state.
✨ IMPROVEMENTGPUTweaks: Extended DPC/ISR Latency with RmDisableCEC=1, RmDisableDisplayPowerSaving=1 for reduced DPC overhead.
🪛 FIXGPUTweaks: Fixed missing GSP Firmware tweak — was defined but never loaded in the UI. Now available and active in Performance profile.
🪛 FIXNETWORK-EXTRAS.PS1: removed the pnputil /remove-device + /scan-devices block that uninstalled and re-enumerated every network adapter - Windows recreates the interface config on re-scan, wiping manually configured DNS servers (NameServer reverts to DHCP). Bindings are still disabled live (Disable-NetAdapterBinding applies immediately without removing devices). Manual DNS now survives reinstallation.
🪛 FIXNETSH_TCPIP_APPLY.PS1 and FINALIZE6.CMD: removed Disable-NetAdapter/Enable-NetAdapter blocks that were resetting manually configured DNS. DNS settings are now preserved after playbook installation.
🆕 NEWAuto Hide mouse cursor: Allows you to make the cursor disappear like in certain video players, but for everything.

✨ IMPROVEMENT Complete rewrite of the playbook from scratch.
🪛 FIX Services: Reintegrated ~200+ services from Beta2 playbook. services.yml expanded from 48 to 331 lines (245 unique services, 0 duplicates). Categories: Telemetry, Troubleshooting, Xbox, Network, Devices, Search, System, ACPI/Power/Drivers, Hyper-V, per-user sync wildcards.
🪛 FIX Nvidia_DLSS_GOM.bat: Complete rewrite. Default mode is now auto-download (silent). /MENU flag for interactive mode. Anti-boucle elevation guard via temp flag. Admin check uses whoami /groups (S-1-16-12288) instead of net session (which fails when LanmanServer is Manual). Temp files moved to %TEMP%.
🪛 FIX GPUTweaks: DLSS Updater button now passes /AUTO argument to Nvidia_DLSS_GOM.bat.
✨ IMPROVEMENT GPUTweaks NVIDIA tweaks: Replaced all previous tweaks with 30 individual tweaks sourced from Configure Nvidia.bat (DLSS indicator, DevTools, tray icon, power saving, runtime power mgmt, perf counters, HD audio D3Cold, RMPowerFeature, HW fault buffer, DPC queueing, engine gatings, GC6, hot plug, FBSR, L2 compression, MS hybrid, non-contiguous alloc, LRC coalescing, registry caching, D3 PC latency, compstat access, panel refresh, driver logging, nvlddmkm logging, debug features, telemetry, NvTelemetry service, ECC, HDCP).
✨ IMPROVEMENT GPUTweaks AMD tweaks: Added 19 individual tweaks sourced from Configure AMD.bat (light sleep, ULPS, Radeon Boost, 3D clock gating, display/media clock gating, graphics/media power gating, powerdown, ASPM, performance mode, ClkReq, FBC, UVD, tile downgrade, spread spectrum, power saver, AMD services, auto update, animations).
✨ IMPROVEMENT GPUTweaks: Bilingual tooltips (FrEn). All tweak names, descriptions, and detailed descriptions now display in French if system language is French, English for all other languages. Uses CultureInfo.CurrentUICulture.TwoLetterISOLanguageName.
🪛 FIX SYSTEM_TWEAKS.PS1: GlobalTimerResolutionRequests no longer forced to 0. Left at Windows default — TimerControl app now has full control over timer resolution.
🪛 FIX SCHEDULED-TASKS-DISABLE.PS1: Removed ProgramDataUpdater and Microsoft Compatibility Appraiser from task list (protected by Windows, caused 10x retry + failure log spam). Fixed double UTF-8 BOM corruption.
🪛 FIX TELEMETRY.PS1: Removed #Requires directives (AME handles elevation). Fixed UTF-8 BOM encoding issues. Final Write-Log string moved to variable to avoid AME copy corruption of inline double-quoted strings.
🪛 FIX tasks.yml: Removed ProgramDataUpdater, StartupAppScan, Microsoft Compatibility Appraiser scheduled tasks (protected by Windows — AME retry spam).
🪛 FIX APPX-REMOVER.PS1: Added Microsoft.Windows.AugLoop.CBS to protected packages (system package used by Windows Update — always in use, removal fails with 0x80073D02). Skip S-1-5-18 (SYSTEM) SID in per-user removal loop (Remove-AppxPackage does not support SYSTEM — "Value is not within the expected range"). Removed AugLoop.CBS from APPX-REMOVE-LIST.TXT.
🪛 FIX LOW-LATENCY-PROFILE.PS1: ViVeTool now bundled locally in Executables\LexBoosTOS\Utilities\ViVeTool\ (4 files: ViVeTool.exe, Albacore.ViVe.dll, FeatureDictionary.pfs, Newtonsoft.Json.dll). Script uses local copy instead of downloading from GitHub. Falls back gracefully if not found (exit 0). Works offline.
🪛 FIX writeStatus: All 50+ writeStatus strings in YAML files shortened to maximum 25 characters for AME UI compatibility.
🪛 FIX DEVICES.PS1 Configure-Ntfs: powercfg disk power settings now query GUID existence before applying (powercfg -query SCHEME_CURRENT SUB_DISK <GUID>). Eliminates "The specified power management mode, subgroup, or setting does not exist" errors for GUIDs not present in the current power scheme.
🪛 FIX services.yml ACPI/POWER/DRIVERS: All 16 services (acpipagr, AcpiPmi, acpitime, acpiex, intelpmt, PRM, WmiAcpi, bam, dam, iorate, fvevol, rdyboost, Dfsc, bowser, mrxsmb, mrxsmb20) changed from Disabled (4) to Manual (3). Devices can start when needed instead of being permanently disabled.
🪛 FIX services.yml: Added rdpbus (RDP Device Redirector Bus), CompositeBus (Composite Bus Enumerator), umbus (UMBus Root Bus Enumerator) as Manual (3).
🪛 FIX services.yml Hyper-V: HvHost and all 9 vmic* guest services changed from Automatic (2) to Manual (3). Only needed inside VMs.
🪛 FIX DISM-FEATURES.PS1: Removed MSRDC-Infrastructure from disabled features list. Was removing the RDP Bus Redirector device (rdpbus). Now preserved.
🪛 FIX LexBoosT Ram Cleaner: Scheduled task replaces shell:startup shortcut. Start with Windows now uses task scheduler trigger with -minimized for silent tray startup. No more UAC after initial setup.
🪛 FIX network.yml: NETSH-EXTRAS.PS1 and NETWORK-EXTRAS2.PS1 merged into NETWORK-EXTRAS.PS1. Single execution point for RSS/NetBIOS/QoS/SMB/LanmanServer/Maintenance.
🪛 FIX KILL_PROCESSES.PS1: added new process names `TodoListManager` and `LexBoosT_Ram_Cleaner` (old `TodoGUI_Pro` / `LexBoosTRamCleaner` kept for compatibility).
🪛 FIX custom.yml: `powercfg /h /type reduced` now checks return code and skips gracefully when hibernation is disabled by secure policy / S0 modern standby.
🪛 FIX EDGE-LATENCY.PS1: skips user hives already loaded (logged-on user) instead of failing with "file in use" on `reg load`.
🪛 FIX NETWORK-EXTRAS.PS1: scheduled task disable now checks task existence and exit code before logging success, avoids false positives on systems without MaintenanceConfigurator/IdleMaintenance/RegularMaintenance.
🪛 FIX LexBoosT HideIcons Desktop: Scheduled task replaces shell:startup shortcut. Start with Windows now uses task scheduler trigger with -minimized for silent tray startup. No more UAC after initial setup.
🪛 FIX LexBoosT Todo List Manager: Scheduled task replaces shell:startup shortcut. Start with Windows now uses task scheduler trigger with -minimized for silent tray startup. No more UAC after initial setup.
🪛 FIX Hyper-V Compatibility: HvHost service set to Automatic (was Manual). Ensures Hyper-V host infrastructure always starts.
🪛 FIX Hyper-V Compatibility: 9 vmic* guest integration services set to Automatic (vmicguestinterface, vmicheartbeat, vmickvpexchange, vmicrdv, vmicshutdown, vmictimesync, vmicvmsession, vmicvss, vmvss). Prevents broken triggers from blocking guest heartbeat/time sync/shutdown/VSS.
🪛 FIX Hyper-V Compatibility: TermService (Remote Desktop) set to Manual instead of Disabled. Preserves Hyper-V Enhanced Session Mode (clipboard sharing, drive redirection, audio passthrough in VMConnect).
🪛 FIX Hyper-V Compatibility: NDIS WatchDog re-enabled (DisableNDISWatchDog=0). Hyper-V virtual switches (vEthernet) depend on NDIS for network recovery on driver hangs.
🪛 FIX Hyper-V Compatibility: SvcHostSplitDisable now excludes Hyper-V services (vmic|vmms|vmcompute|HvHost|nvspwmi|vmwp). Prevents Hyper-V services from sharing svchost with non-Hyper-V services, preserving isolation.
🪛 FIX Hyper-V Compatibility: Windows Containers CmCleanup scheduled task left enabled (was disabled in FINALIZE5.CMD). Prevents orphaned container layer accumulation.
🪛 FIX Hyper-V Compatibility: DMA enumeration policy block removed from FINALIZE1.CMD. Prevents interference with Hyper-V Discrete Device Assignment (DDA) for PCIe passthrough.
🪛 FIX SYSTEM_TWEAKS.PS1: TimeSlip changed from 1 to 0. Undocumented kernel key — value 1 caused clock drift on some chipsets. Reverted to Windows default (stable).
🪛 FIX appx.yml: 9 media codecs excluded from debloat (WebMedia, RawImage, HEIF, HEVC, VP9, AV1, AVC Encoder, MPEG2, WebpImage). Removal prevented opening common photo/video formats without manual reinstall.
✨ IMPROVEMENT services.yml: VERIFY-SERVICES.PS1 script added at end of phase. Validates 67 critical services (40 Disabled + 27 Auto) are in expected state after configuration. Logs mismatches without blocking the playbook.
✨ IMPROVEMENT system.yml (new): Fault Tolerant Heap disabled (HKLM + WOW6432Node). FTH throttles apps 10-50x after 5+ crashes — disabled, crashing apps just crash without performance degradation on next launch.
✨ IMPROVEMENT explorer.yml: ForegroundLockTimeout=0 (HKCU + .DEFAULT). Prevents background apps from stealing focus while typing in another window.
✨ IMPROVEMENT explorer.yml: AlwaysUnloadDll=1. Explorer frees RAM from unused DLLs instead of keeping them cached.
✨ IMPROVEMENT gaming.yml: Fullscreen Optimizations disabled (GameDVR_FSEBehaviorMode=2, GameDVR_HonorUserDSEBehaviorMode=1). Restores true Fullscreen Exclusive (DWM bypassed) to reduce input lag in games.
🪛 FIX dwm.yml: MaxQueuedPresentBuffers 2→3 (Windows default). Fixes upside-down desktop icons during drag-and-drop. FrameLatency removed (undocumented key interfering with DWM buffer synchronization).
🪛 FIX explorer.yml: FR regional format block removed (sShortDate, sDecimal, iFirstDayOfWeek, etc.). Was forcing FR format for all users, breaking US, Chinese and other locales.
✨ IMPROVEMENT custom.yml + system.yml: Fast Startup enabled with reduced hiberfil (powercfg /h /type reduced, FastBoot=1). hiberfil.sys at ~20% of RAM instead of 40-75%. Eliminates black screen with spinner before logon, without sacrificing too much disk space.
🪛 FIX MSA Login Chain: NoGenTicket HKCU+HKLM set to 0 (was 1). Half-disabled Microsoft Account chain (TokenBroker/wlidsvc ON but NoGenTicket/CloudExperienceHost/Provisioning tasks OFF) broke login for MSA users without local password. Restored coherent MSA support.
🪛 FIX CloudExperienceHostOOBE AutoLogger: removed forced Start=0 (telemetry.yml). Required for MSA OOBE login flow.
🪛 FIX Scheduled Tasks MSA: Provisioning\Logon, CloudExperienceHost\CreateObjectTask, AccountHealth\RecoverabilityToastTask no longer disabled (FINALIZE5.CMD). Required for MSA login/recovery.
🪛 FIX GlobalTimerResolutionRequests comment clarified in FINALIZE1.CMD: enables NtSetTimerResolution API (does NOT set 0.5ms itself — that's done by SetTimerResolution.exe).
🪛 FIX LexBoosT Defender Manager: VBS/HVCI, hypervisor, LSA RunAsPPL, and VulnerableDriverBlocklist removed from Optimized script (CreateOptimizeScript). Optimized mode now ONLY disables Defender features — all boot-critical security features (VBS, HVCI, hypervisor, LSA, driver blocklist) are preserved. Zero conflict with playbook VBS=ON policy.
🪛 FIX LexBoosT Defender Manager: Smart App Control (VerifiedAndReputableTrustModeEnabled, SmartLockerMode, SMARTLOCKER, VerifiedAndReputablePolicyState) removed from BOTH Optimized and Default scripts. SAC is a one-time OOBE decision — forcing it in either direction is irreversible without Windows reinstall. PUAProtection kept (independent feature).
🪛 FIX LexBoosT Defender Manager: Safe Mode reboot flow hardened — user is asked for restart confirmation BEFORE bcdedit /set safeboot is written. If user cancels, the RunOnce script entry is cleaned up (reg delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce) so next manual boot stays normal. Previously safeboot was written before the dialog, making "No" misleading.
🪛 FIX VBS settings: Defender Manager "Optimized" incompatibility warning removed — no longer applicable since Optimized does not touch VBS/HVCI. (vbs.yml removed — VBS settings now managed by LexBoosT Defender Manager)
✨ IMPROVEMENT GPUTweaks: ApplyTweak now checks WriteDwordValue return value. If registry write fails, the key is skipped (continue) and not added to backup — prevents silent failures where backup is saved but value was never written.
✨ IMPROVEMENT TimerControl: TimerDefaultValue changed from 5200 (0.520ms) to 5000 (0.500ms). Default timer resolution now matches the minimum value (TimerMinValue=5000).
✨ IMPROVEMENT FINALIZE1.CMD: GlobalTimerResolutionRequests registry key no longer forced by playbook. Timer resolution is now configured exclusively via TimerControl app — playbook stays neutral, user controls everything from the TimerControl UI.
✨ IMPROVEMENT Force Timer Resolution.xml: default --resolution argument updated from 5200 to 5000 in the scheduled task template.
✨ IMPROVEMENT GPUTweaks: Revert now restores original registry values instead of deleting everything. Original state persisted to C:\ProgramData\LexBoosTOS\GPUTweaks\<vendor>\<tweak>.json before Apply.
🪛 FIX TimerControl: unified schtasks /delete path (removed double backslash). DisableTimerResolution now checks task deletion result and returns warning on failure instead of silent "success".
✨ IMPROVEMENT TimerControl: StopMonitoring no longer hardcodes 0.5080ms — queries actual timer resolution via NtQueryTimerResolution.
✨ IMPROVEMENT TimerControl: DisableButton_Click now checks for Error/Failed in result before showing Success dialog.
✨ IMPROVEMENT Added Themed Terminal in option in AME.
🪛 FIX SYSTEM_TWEAKS.PS1: SearchIndexer.exe, RuntimeBroker.exe, backgroundTaskHost.exe, and sihost.exe CpuPriorityClass raised to 3 (Normal) to fix empty Start Menu search results on Windows 11 25H2/26H2.
🪛 FIX Laptop detected: skipping max refresh-rate enforcement. Set your preferred refresh rate manually in Settings or GPU driver panel.
🪛 FIX gaming.yml: removed tearing/VSync-breaking keys (AllowTearing=1, QueuedPresentLimit=1, DisableBoostedVSyncVirtualization=1, GameDVR_FSEBehaviorMode=2). Fixes broken FPS limiters, V-Sync and screen tearing reported by users.
🪛 FIX dwm.yml: removed UseCopyOnPresent=1 and reduced DWM tweaking (DWM_MAX_BUFFER_AGE, DWM_TRIPLE_BUFFER, OverlayMinFPS removed). Restores stable DWM presentation.
🪛 FIX GPUTweaks: removed 'Disable MPO' tweak and MPO mention from Low Latency Tweaks. MPO/OverlayTestMode is a Windows-wide tweak and is out of scope for a GPU-vendor-only utility.
🪛 FIX GPUTweaks .nip profiles: VRR/G-SYNC and Vertical Sync values aligned between standard and G-SYNC profiles. Standard profile keeps application-controlled VSync; G-SYNC profile keeps VSync ON + Smooth V-Sync.
✨ IMPROVEMENT GPUTweaks: NVIDIA FTS keys now written to both `HKLM\SYSTEM\CurrentControlSet\Services\nvlddmkm\FTS` and `\Parameters\FTS` for compatibility with old and new NVIDIA drivers (post-581.15 moved FTS).
✨ IMPROVEMENT GPUTweaks: RmGpsPsEnablePerCpuCoreDpc now written to five locations (GraphicsDrivers, nvlddmkm, nvlddmkm\NVAPI, nvlddmkm\Global\NVTweak, GraphicsDrivers\Power) per community reference scripts.
✨ IMPROVEMENT Updates LexBoosT Todo List Manager, LexBoosT Ram Cleaner Pro and LexBoosT Desktop Icons Toggle: Removal of the application's minimize button and the Close button puts the application in the notification area.
✨ IMPROVEMENT Update LexBoosT Tools Launcher to v2.4: Allows you to launch the application in the notification area, search for automatic updates at startup or depending on the time you give it. The Close button also puts the application in the notification area.
🪛 FIX Revert ifeo changes.
🪛 FIX GPUTweaks: Added NVIDIA Control Panel download button.
✨ IMPROVEMENT LexBoosT Discord Debloater: "Debloat" button replaced by "Optimize": settings.json tweaks (SKIP_HOST_UPDATE, HW accel/auto-start deactivation), keep-list module (core/modules/utils/voice), cleaning caches/logs/crashpad, deletion of old app-* versions, deactivation of Windows startup, IFEO CpuPriorityClass=3 (Above Normal).
✨ IMPROVEMENT BCD optimizations: Set-BcdOptimizations rewritten with per-CPU conditional logic. Applies disabledynamictick=yes, deletes useplatformclock/useplatformtick, plus disableelamdrivers, isolatedcontext No, nx optin, bootmenupolicy Legacy.

🆕 2 new features

✨ IMPROVEMENT DEVICES.PS1 Set-DesktopPowerOptimizations: added hibernation policy reinforcement (AllowHibernate=0, HibernateChecksummingEnabled=0, EnableMinimalHiberFile=0, HiberFileSizePercent=0, ForceHibernateDisabled=1). DisableIdleStatesAtBoot=2 prevents deep idle during boot. SleepStudy directory permissions blocked (icacls remove SYSTEM/Administrators). DMA remapping compatibility disabled across all services to reduce IOMMU overhead. All desktop-only (skipped on laptops via Get-CachedLaptopStatus).
✨ IMPROVEMENT DEVICES.PS1 Set-DrivesConfiguration: enables disk write cache (UserWriteCacheSetting=1) and marks cache as power-protected (CacheIsPowerProtected=1) on all enumerated disk drives. Safe for laptops (battery acts as power protection).
✨ IMPROVEMENT DEVICES.PS1 Set-DrivesConfiguration: NTFS optimizations — USN change journal disabled (reduce disk writes), NTFS metadata in non-paged pool (enablenonpagedntfs=1, faster access), disk quotas disabled on C:, extended characters in 8.3 names allowed (allowextchar=1).
✨ IMPROVEMENT power.yml: PlatformRoleOverride=0 added — lets Windows auto-detect desktop/mobile platform role correctly, preventing mistaken mobile power policies on desktop.
✨ IMPROVEMENT gaming.yml GPU Scheduler: 6 keys added to ControlSet001\GraphicsDrivers\Scheduler — AdjustWorkerThreadPriority=0, AudioDgAutoBoostPriority=0, AutoSyncToCPUPriority=0, ForegroundPriorityBoost=0, FrameServerAutoBoostPriority=0, QueuedPresentLimit=1. Reduces GPU scheduling overhead and render queue latency.
✨ IMPROVEMENT gaming.yml GPU Drivers: DisableVersionMismatchCheck=1 (skip driver version mismatch rejection), DisableBoostedVSyncVirtualization=1 (reduce VSync buffering overhead). Both in ControlSet001 for next-boot persistence.
✨ IMPROVEMENT dwm-optimization.yml Advanced Visual & Latency: 9 keys added — AnimationsShiftKey=0, ParallelModePolicy=1 (simultaneous surface composition), EnableBloom=0, EnableCpuClipping=0 (GPU-side clipping), EnableMegaRects=0, ForceDesktopTreeFullDirty=0, GammaBlendPencil=1, GammaBlendWithFP16=1 (FP16 precision blending), MousewheelAnimationDurationMs=100 (snappier scroll).
✨ IMPROVEMENT advanced-system-optimization.yml: FeatureSettings=1 enables memory management feature flags. NtfsDisableVolsnapHints=1 disables VSS snapshot hints to reduce disk I/O stutters during gaming. Executive worker threads zeroed (AdditionalCriticalWorkerThreads, AdditionalDelayedWorkerThreads, TickcountRolloverDelay, KernelWorkerTestFlags) — no extra threads above kernel defaults.
✨ IMPROVEMENT telemetry.yml: WTDS telemetry data service disabled (ServiceEnabled=0). Performance diagnostic tracing disabled at kernel level (DisableDiagnosticTracing=1).
✨ IMPROVEMENT privacy.yml: End-of-Service notifications disabled (DiscontinueEOS=1). Auto-removal of unused language packs blocked (BlockCleanupOfUnusedPreinstalledLangPacks=1). Push notification toasts disabled globally (ToastEnabled=0, HKCU).
✨ IMPROVEMENT cloud-content.yml: online tips in Explorer disabled (AllowOnlineTips=0). Automatic device metadata download blocked (PreventDeviceMetadataFromNetwork=1).
✨ IMPROVEMENT ceip.yml: Visual Studio 2017 Software Quality Metrics telemetry opted out (VSCommon SQM OptIn=0).

✨ IMPROVEMENT explorer.yml: UseCompactMode enabled (1) — compact mode in File Explorer for denser file listing. Auto-scan and auto-voice accessibility triggers disabled (selfscan=0, selfvoice=0) — prevents accidental Narrator activation during gaming.
✨ IMPROVEMENT DISM-FEATURES.PS1: 2 features disabled — WindowsMediaPlayer. 2 capabilities removed — App.StepsRecorder (Steps Recorder), Media.WindowsMediaPlayer (WMP legacy). Reserved Storage disabled (frees ~7 GB). New Remove-Capability helper function added alongside existing Update-Feature.
✨ IMPROVEMENT win-settings.yml SettingSync: 7 keys added — HKCU SyncPolicy=5 (master switch), 5 per-category Groups disabled (Accessibility, BrowserSettings, Credentials, Personalization, Windows), HKLM DisableSyncOnPaidNetwork=1. Complements existing HKLM Disable*Sync policies and disabled SettingSync scheduled tasks.
🪛 FIX Fix URL for chocolatey installation.
🪛 FIX Fix ps1, bat, cmd, vbscript in New on context menu.
🆕 NEW MAX-REFRESH-RATE.PS1: new Devices script that scans all connected displays (\\.\DISPLAY1 through \\.\DISPLAY10) and sets each display to its maximum supported refresh rate while preserving native resolution, bit depth, position and orientation. Uses EnumDisplaySettings to enumerate modes and ChangeDisplaySettingsEx with CDS_TEST + CDS_UPDATEREGISTRY. Multi-monitor ready (each display optimized independently). Added to devices-scripts.yml playbook phase. PowerShell 5.1 compatible, no admin required.
🆕 NEW LexBoosT-v3.0-dark.theme: added missing Crosshair (precision-select.cur) and IBeam (text-select.cur) cursor roles — all 15 Colloid cursors now mapped in theme.
🪛 FIX ONED.CMD: unregisters FileSyncShell*.dll before deleting AppData\Local\Microsoft\OneDrive folder to prevent locked-DLL leftover shell extensions after OneDrive removal.
🪛 FIX EDGE.PS1 Uninstall-EdgeUpdate: per-user Cleanup now deletes AppData\Local\Microsoft\EdgeUpdate folders, removes HKCU Run key "Microsoft Edge Update" for all user hives, and unregisters MicrosoftEdgeUpdate* scheduled tasks. Switch statement fixed to route "EdgeUpdate" mode (was hitting default/Invalid mode).
🪛 FIX FINALIZE5.CMD USO_UxBroker: replaced schtasks /Change /Disable with PowerShell Disable-ScheduledTask (COM API, bypasses protection on system tasks where schtasks.exe silently fails).
🪛 FIX DISM-FEATURES.PS1: added Internet-Explorer-Optional-amd64 to disabled features (removes IE from Windows Features, safe on Win11 where already retired).
🪛 FIX drivers.yml: removed all ExcludeWUDriversInQualityUpdate entries (HKLM Policies, HKLM UX\Settings, HKCU Policies) — delegated to LexBoosT GPU Tweaks. Fixes "Partial" state on LexBoosT GPU Tweaks System Tweaks button after playbook installation.
🪛 FIX WIPE_STARTMENU.PS1: fixed registry path resolution — replaced $hive.Name (returns bare "HKEY_USERS\S-...") with $hive.PSPath (returns "Microsoft.PowerShell.Core\Registry::HKEY_USERS\S-..."). The bare path caused Get-ItemProperty to silently fail, skipping all user hive processing (CloudStore tilegrid clearing, start.bin deletion, layout file copying). The wipe appeared to do nothing despite exiting cleanly.
🪛 FIX FILE_ASSOCIATIONS.PS1: fixed missing .bat, .cmd, .reg entries in New context menu — added parent extension keys (.bat, .cmd, .reg) to $regKeys before their ShellNew subkeys (were only creating subkeys, silently failing when parent didn't exist). Added default ProgID values (batfile, cmdfile, regfile) and PerceivedType removal for all 5 extensions (.bat, .cmd, .ps1, .reg, .vbs) to prevent Windows 10/11 from suppressing ShellNew entries.
🪛 FIX FINALIZE2.CMD Audio Tweaks: MMCSS Audio/ProAudio tasks deprioritized — Priority 8→1, GPU Priority 8→1, SFIO Priority High→Normal, Background Only True→False. Audio no longer steals CPU/GPU resources from games, fixing FPS drops when sound is active in Overwatch and other competitive FPS titles.
🪛 FIX audio-latency.yml: GPU Priority 8→1, SFIO Priority High→Normal. Aligned with FINALIZE2.CMD to prevent audio/render resource contention.
✨ IMPROVEMENT gaming.yml: Games MMCSS Priority 6→8 (max, beats audio at 1). SystemResponsiveness 14%→10% — more CPU available for games, absolute safe minimum for audio.
🪛 FIX gaming.yml: DisableCoInstallers 1→0 — no longer breaks Realtek/Creative audio drivers. Broken audio drivers were causing CPU overload and FPS drops in games.
🪛 FIX LexBoosT Toolbox: all tools now launch as Administrator by default — fixes issues where certain tweaks and scripts would silently fail due to insufficient privileges.
🪛 FIX LexBoosT Packages Manager: application now auto-restarts after module installation to ensure all changes are properly applied.

🆕 16 new features

💥 5 breaking changes

🪛 FIX DEVICES.PS1 Set-DrivesConfiguration hang fixed: replaced Get-PhysicalDisk -SerialNumber (can hang on some NVMe/SSD) with DeviceId-based lookup. Playbook no longer freezes at "Configuring Drive Optimizations".
🪛 FIX HKCU registry propagation fixed: replaced all HKEY_CURRENT_USER\ with HKCU\ in mouse-keyboard.yml (2 occurrences) and explorer.yml (1 occurrence). APPLYDUHIVE.PS1 pattern-matches HKCU* — the long form was silently skipped, causing mouse/keyboard settings to be missing from the registry after installation.
🪛 FIX APPLYDUHIVE.PS1 Get-UserProfilesOffline bug fixed: replaced return with continue inside ForEach-Object pipeline. return was terminating the entire pipeline at the first built-in profile (Default/Public), preventing all subsequent user profiles from being discovered and processed.
✨ IMPROVEMENT APPLYDUHIVE.PS1 now scans .CMD and .PS1 scripts for HKCU paths: previously only YAML files were scanned, causing ~45 HKCU values from FINALIZE1-3.CMD (notifications, accessibility, DeviceAccess, ContentDeliveryManager, etc.) and ~10 from VISUAL.PS1/OPTIMIZE-MOUSESMOOTHINGCURVES.PS1/ICONS_DESK.PS1 to be missing from Default User hive. Regex-based extraction covers both HKCU\ and HKEY_CURRENT_USER\ formats.
🪛 FIX IFEO priority conflicts fixed: aligned ifeo.yml with system-process-performance-optimization.yml — sihost.exe CpuPriority 1→2 (Normal, fixes Win11 taskbar lag), IoPriority 0→2 (Normal), ctfmon.exe CpuPriority 5→2 (Normal), csrss.exe CpuPriority 3→4 (Above Normal).
🪛 FIX NVIDIA EnableGR535 duplicate removed from gaming.yml: already handled by GPUTweaks (FTS Tweaks). GPUTweaks is now the single source of truth for all GPU driver tweaks (NVIDIA/AMD/Intel).
🪛 FIX Privacy Location conflict fixed: ConsentStore location set to Allow (was Deny→Allow→Deny due to duplicate entries). Apps requiring location access now work correctly.
🪛 FIX InkWorkspace conflict fixed: AllowWindowsInkWorkspace set to 1 in FINALIZE3.CMD (was 0, conflicting with explorer.yml). Preserves stylus/pen compatibility.
✨ IMPROVEMENT BCD x2apicpolicy enable: added to DEVICES.PS1 Set-BcdOptimizations. Improves interrupt routing on modern CPUs (Intel 12th+, AMD Zen 3+).
✨ IMPROVEMENT BCD useplatformtick yes (AMD): added to DEVICES.PS1 Set-BcdOptimizations. Forces TSC as tick source on AMD CPUs for better timer precision.
🪛 FIX LSO/RSC alignment: DEVICES.PS1 network settings aligned with YAML — *LsoV1IPv4, *LsoV2IPv4, *LsoV2IPv6 set to 0 (disabled), *RscIPv4, *RscIPv6, *UdpRsc, ForceRscEnabled set to 0 (disabled), ReceiveSegmentCoalescing set to Disabled. Consistent low-latency network configuration across all sources.
🪛 FIX Dead code removed: crash-control.yml deleted (FINALIZE3.CMD covers same values), DisablePageCombining removed from advanced-system-optimization.yml (FINALIZE4.CMD covers via Disable-MMAgent), ExcludeWUDriversInQualityUpdate duplicate removed from updates.yml (already in drivers.yml), Crash Control/NoDriveTypeAutoRun/NoAutorun duplicates removed from FINALIZE3.CMD (already in YAML).
✨ IMPROVEMENT DirectStorage 1.2+ optimizations: EnableDirectStorage=1, EnableOptimizations=1 in gaming.yml. Faster game loading on NVMe Gen4+ drives.
✨ IMPROVEMENT VRR for windowed apps: VRRForWindowedApps=1 in gaming.yml. Enables Variable Refresh Rate for borderless/windowed games (Windows 11 25H2+).
✨ IMPROVEMENT Auto HDR enhancements: AutoHDREnabled=1, AutoHDRIntensity=2 in gaming.yml. Improved automatic HDR quality (Windows 11 25H2+).
🪛 FIX DEVICES.PS1 HiberbootEnabled duplicate removed: HiberbootEnabled=0 removed from additional-performance-optimization.yml (DEVICES.PS1 Set-HibernationSettings covers it). Policies delete and SleepStudyEnabled kept (not in DEVICES.PS1).
🪛 FIX DEVICES.PS1 USB Selective Suspend bug fixed: powercfg value corrected from 1 (enabled) to 0 (disabled) for USB Selective Suspend Setting (GUID 48e6b7a6-50f5-4782-a5d4-53bb8f07e226).
✨ IMPROVEMENT DEVICES.PS1 core parking refactored: new Set-CoreParkingDisabled helper function replaces 3 identical code blocks (Intel/AMD X3D single-CCD/AMD). ~24 lines of duplicated code eliminated.
✨ IMPROVEMENT DEVICES.PS1 system detection cached: new Get-CachedLaptopStatus and Get-CachedVMStatus functions cache WMI/CIM results. 9 Test-Laptop calls and 1 Test-VM call replaced — reduces redundant hardware queries.
🆕 NEW Pre-Installation Backup: System snapshot created before any modifications (system restore point, targeted registry export from YAML configs, service state, AppX snapshot, BCD export). Backup saved to %ProgramData%\LexBoosTOS\Backup with timestamped manifest.
🆕 NEW Rollback System: ROLLBACK.ps1 restores BCD, targeted registry keys, and service startup types from pre-installation backup. "Restore LexBoosT OS Backup" context menu added to desktop.
🆕 NEW Custom OS Detection: 24 custom Windows builds (AtlasOS, ReviOS, Tiny11, Ghost Spectre, etc.) detected via ProductName, EditionID, OEM info, folder paths, and registry keys. Installation aborted with error message if detected — prevents catastrophic playbook conflicts.
🆕 NEW AppX Snapshot Before/After: APPX-REMOVER.ps1 now saves pre-removal package list, post-removal list, and generates a diff report of removed packages in C:\Windows\LexBoosTOS\Logs.
🆕 NEW System Configuration Log: Writes Windows version, architecture, CPU, RAM, and user info to C:\Windows\LexBoosTOS\Logs\lexboost-system-config.txt for support/debug.
🆕 NEW Active Setup Stubs Cleanup: CLEANUP-ACTIVE-SETUP.ps1 clears StubPath entries and Run keys for browsers (Brave, Chrome, Edge, Firefox, Opera, Vivaldi, Zen) and OneDrive — prevents first-logon popups.
🆕 NEW ConsentStore Full Lockdown: 32 capabilities set to Deny (activity, appointments, bluetooth, calendar, callHistory, cellularData, chat, contacts, email, eyeTracker, gazeInput, generativeAI, humanPresence, humanInterfaceDevice, location, motion, notifications, passkeys, phoneCall, phoneCallHistory, radios, spatialPerception, backgroundSpatialPerception, tasks, trustedDevices, userAccountInformation, userDataTasks, userNotificationListener, voiceActivation, wifiData, wifiDirect). Applied to HKLM, HKCU\.DEFAULT, and all live user SIDs via PowerShell. Webcam and microphone remain Allow.
🆕 NEW Offline NTUSER.DAT Processing: APPLYDUHIVE.ps1 now scans all C:\Users\ profiles, loads each NTUSER.DAT, applies HKCU settings, and unloads — previously only processed Default user.
🆕 NEW Disable Windows Transparency: New option in AME — "Disable Windows Transparency" under Visual options. Sets EnableTransparency=0 (HKCU\Themes\Personalize) to remove acrylic/blur effects on taskbar, Start menu, and window borders for a clean opaque look.
🆕 NEW Windows Update Granular Policies: AUPowerManagement=0 (no wake for updates), DeferFeatureUpdates=1 + 365 days, AUOptions=2 (notify before download), ExcludeWUDriversInQualityUpdate=1, TargetReleaseVersion=1.
✨ IMPROVEMENT DWM Optimization centralized: 60 registry keys consolidated from 5 files into 1 (registry\system\dwm-optimization.yml), sourced from verified community tweaks. Gain: unified DWM tuning, zero redundancy.
✨ IMPROVEMENT DWM Categories: Reorganized from A→K to sequential A→I. New Category B (Buffer & Sync) added; Schedule (E), Flip Model (F), MPO (G), Visual (H), MMCSS (I) renumbered accordingly.
✨ IMPROVEMENT DWM Rendering Pipeline: disabled legacy rendering modes (DisallowNonDrawListRendering), caching (DisableDrawListCaching, EnableEffectCaching), and image processing (EnableImageProcessing). Enabled copy-on-present, scanout caching, virtual surface flattening, surface discard on minimize, and Advanced Direct Flip. Gain: lighter desktop compositing, ~1-3ms faster frame delivery.
✨ IMPROVEMENT DWM Buffer & Sync: buffer age set to 1 frame (DWM_MAX_BUFFER_AGE/DWM_MAXIMUM_BUFFER_AGE), triple buffering enabled (DWM_TRIPLE_BUFFER). Gain: tear-free desktop on all display types.
✨ IMPROVEMENT DWM Telemetry Disabled: all DWM diagnostic, debug, and animation tracking turned off (5 telemetry keys). Gain: zero DWM background logging, ~10-30% lighter dwm.exe CPU usage.
✨ IMPROVEMENT DWM Advanced Composition: disabled primitive reordering, resample overrides, front buffer render checks, overlay auto-qualification, and extended composition filters. Enabled common supersets, dirty expression optimization, and resize optimization. Gain: consistent frame pacing, no micro-stutters from partial updates.
✨ IMPROVEMENT DWM Schedule & Frame Control: frame timing offsets minimized, schedule intervals zeroed. Gain: no background interruptions, tighter frame timing.
✨ IMPROVEMENT DWM Flip Model & Present: Independent Flip fully enabled (HKLM + HKCU), MaxQueuedPresentBuffers set to 2, FrameLatency set to 1 frame. Gain: maximum flip model coverage, lower input lag (16ms at 60Hz vs 33ms).
✨ IMPROVEMENT DWM MPO/Overlays: overlay test mode deleted, OverlayMinFPS set to 0 for dynamic overlay switching. Gain: fix MPO flickering/stuttering in games.
✨ IMPROVEMENT DWM Visual & Animations: thumbnail hibernation turned off (AlwaysHibernateThumbnails=0). Gain: saved GPU memory.
🪛 FIX DWM Corrections: License activation popups (DisableSpecificPopups, DisableExpirationPopups, HideBalloonNotification, DontAskAgain, LicenseInterval) removed from DWM config — these are license-related, not DWM. HighColor set to 1 (30-bit 10bpc HDR preserved). EnableDesktopOverlays set to 1 (Discord/Steam/VLC overlays functional). MegaRects (EnableMegaRects, MegaRectSize, MegaRectSearchCount) removed — Windows manages partial redraw by default.
✨ IMPROVEMENT MMCSS Scheduling consolidated into gaming.yml: SystemProfile root, Games task, and Window Manager task all in one file. Window Manager GPU Priority lowered from 8 to 6 (avoids conflict with Games=8). Window Manager Clock Rate lowered from 10000 to 2000 (avoids CPU overhead). dwm-optimization.yml MMCSS section removed.
🪛 FIX AllowTelemetry consolidated: 5 paths → 1 (HKLM\SOFTWARE\Policies\Microsoft\Windows\DataCollection only). MaxTelemetryAllowed duplicates removed.
🪛 FIX Paint AI keys consolidated: nonstandard CurrentVersion\Policies\Paint removed, only GP path Policies\Microsoft\Paint kept.
🪛 FIX AllowUseDirectFlip removed from gaming.yml (redundant with DisableIndependentFlip in dwm-optimization.yml).
🆕 NEW IFEO (Image File Execution Options): Added CPU priority tuning for 4 processes — MoUsoCoreWorker.exe (High), spoolsv.exe (High), RuntimeBroker.exe (Idle), backgroundTaskHost.exe (Idle). Reduces background CPU contention from Windows Update scan worker and UWP broker during gaming.
🆕 NEW Taskbar: Emoji/Touch Keyboard button now visible in notification area (TipbandDesiredVisibility=1). Quick access to emoji panel without Win+. shortcut.
✨ IMPROVEMENT Timer Precision: TimeBroker forced to highest resolution (13 keys — hardware timer, clock steering, force precision, disable sleep idle). Task Scheduler optimized (17 keys — real-time scheduling, prevent throttling, disable background tasks during gaming, minimum quantum size). Packet Scheduler timer resolution forced. Explorer resource-aware timers disabled. TSC sync policy set to enhanced. Gain: system-wide microsecond timer accuracy, fewer timer-induced micro-stutters, ~1-5ms reduced scheduling jitter.
✨ IMPROVEMENT Dynamic Tick fully disabled: bcdedit + registry kernel + tick duration limits (max/min = 1000). DISABLE_DYNAMIC_TICK environment variable removed (redundant with kernel key). Gain: no tick merging, consistent timer interrupt rate, lower DPC/ISR latency variance.
🪛 FIX MaxDynamicTickDurationSize removed (0xFFFFFFFF = 4 billion was an absurd value for a kernel parameter).
✨ IMPROVEMENT DistributeTimers removed: prevents timer distribution across cores. Gain: reduced cross-core timer migration overhead.
✨ IMPROVEMENT USB Low Latency: XHCI and HUB3 controllers set to LowLatencyMode + ForceFullSpeed. USB audio always-on + isochronous transfer + minimum latency. USB hubs: aggressive suspend disabled, power down prevented. HID USB idle disabled. Gain: lower USB peripheral latency, stable audio on USB DACs/headsets, faster mouse/keyboard response. (DisableLegacyUSBSupport and DisableZeroLengthControlTransfers skipped to preserve Xbox Wireless Adapter / USB 2.0 dongle compatibility.)
✨ IMPROVEMENT USB I/O Queue Tuning: IoQueueWorkItem set to 0xa on xusb22, USBXHCI, and usbhub drivers. Gain: optimized work item queue depth for gaming peripherals.
✨ IMPROVEMENT Disable ESP padding (potentially reduces latency on some UEFI systems).
✨ IMPROVEMENT Defender Optimization: scheduled scans disabled, catch-up scans disabled, scan only when idle, restore point before scan disabled, IOAV download scanning disabled, scan-on-realtime-enable skipped, signature updates reduced to every 24h, common paths/extensions/processes excluded (exe/dll/sys/log/game formats). Gain: less msmpeng.exe CPU/disk I/O during gaming, fewer hard pagefaults from real-time scanning.
✨ IMPROVEMENT Disable WMI AutoLoggers: 27 additional ETW trace sessions (DefenderApi/Audit, ReadyBoot, Tpm, FaceTel, Holographic, TCPIP, Spooler, WiFiDriver×4, WMI_Traces, Setup, OOBE, FilterMgr, etc.) — 41 total autologgers disabled. Gain: further CPU/disk I/O reduction from stopped kernel trace sessions.
🪛 FIX WMI Autologger ControlSet001 → CurrentControlSet: all 14 entries in telemetry.yml and 2 in disable-AI-programs.yml now use CurrentControlSet (survives boot from alternate control set).
✨ IMPROVEMENT Adjust CPU/I/O priorities: fontdrvhost.exe/lsass.exe/sihost.exe/sppsvc.exe → Idle, csrss.exe → Normal/High I/O, ctfmon.exe/SearchIndexer.exe → High — reduces CPU contention from background services.
✨ IMPROVEMENT Disable CrossDeviceResume.exe via debugger trick (auto-kill on launch) — prevents cross-device resume overhead.
✨ IMPROVEMENT Scheduled Tasks: Disable 54 additional background tasks (SysMain, WaaSMedic, Kernel, ReFS, USB notifications, Flighting, Containers, AppData, Input sync×4, Chkdsk, PerformanceTrace, UpdateOrchestrator×4, Feedback×2, ExploitGuard, BitLocker×2, CloudRestore, SettingSync×2, WinINet, InstallService×3, etc.) + delete 5 (EdgeUpdate, MARE, USO_UxBroker, DeviceDirectoryClient). Gain: fewer background CPU/disk wake-ups, leaner task scheduler.
✨ IMPROVEMENT Security & Convenience: LowRiskFileTypes (no SmartScreen for common formats), disable Open File security warning (Zones\3), disable File History, hide disconnected/hidden audio devices. Gain: fewer prompts, cleaner audio panel.
✨ IMPROVEMENT Tips & Nags: Additional AllowOnlineTips disables (PolicyManager + System), disable App Archiving, disable background disk layout optimization (EnableAutoLayout). Gain: zero suggestions, no disk activity from auto-layout.
✨ IMPROVEMENT File Explorer: Remove Gallery/Home/Network namespace pinned folders, disable BAM window hinting throttling, disable account notifications in Start. Gain: cleaner Explorer, fewer background Graph calls.
✨ IMPROVEMENT Kernel & Power: Disable timer coalescing (REG_BINARY), device power management on all Enum bus devices, StorPort NVMe idle power, USB LPM, power telemetry/watchdogs (FxAccounting, DeepIoCoalescing, MSDisabled, PowerWatchdog×5, Sleepstudy, EnergyEstimation, ThermalTelemetry, StandbyConnectivity, HibernateDefault, CS compliance, PEP constraints). Gain: lower DPC/ISR latency, higher sustained clocks.
✨ IMPROVEMENT Session Manager: Disable kernel telemetry (WerUserReporting, WatsonReporting, IoBoosting tracking), disable Config Manager self-healing/virtualization/fast-boot/bugcheck-recovery, disable I/O counters & crash dump driver, enable mutant auto-boost & interrupt steering. Gain: leaner kernel path, fewer deferred calls.
✨ IMPROVEMENT NDIS: Boost receive worker thread priority to 31, disable watchdog/re-enumeration BSOD, disable NBL tracking & debug logging, disable NIC power saver & NAPs (desktop only). Gain: lower network stack latency.
✨ IMPROVEMENT Input: Disable touch palm rejection delay zones, disable raw mouse throttling timers. Gain: reduced input latency.
✨ IMPROVEMENT Desktop-only guard: All power management disables (USB LPM, NVMe idle, NDIS suspend, kernel parking/serialization) skipped on laptops via chassis/battery detection. Gain: preserves battery life on portables.
✨ IMPROVEMENT Improved LexBoosT OS Wallpaper.
✨ IMPROVEMENT Reativate GameBar\GameDVR. (On Ryzen 9 X3D CPUs (7950X3D/9950X3D), Game Bar is required for proper core parking. It helps Windows direct games to the 3D V-Cache cores. Disabling it can cause a 5-10% performance loss in games.)
✨ IMPROVEMENT CPU-aware core parking: core unparking (CPMINCORES, registry visibility, ValueMax) now applied only on Intel, AMD single-CCD X3D, and AMD non-X3D. Skipped on AMD dual-CCD X3D (Ryzen 9 7950X3D/9950X3D) where Game Bar manages parking for the 3D V-Cache CCD. Prevents performance loss on high-end X3D CPUs.
🪛 FIX AMD 3D V-Cache detection enhanced: now matches known models (5800X3D, 7800X3D, 7900X3D, 7950X3D, 9800X3D, 9900X3D, 9950X3D) in addition to "X3D" pattern match.
🪛 FIX Intel hybrid detection expanded: now matches Core Ultra 200+ (Arrow Lake) and Core Ultra 100+ (Meteor Lake, Lunar Lake) in addition to 12th-14th gen.
🪛 FIX TSX detection hardened: Intel Haswell/Broadwell/Skylake CPUs correctly identified as vulnerable to CVE-2019-11135 (TSX Async Abort). DisableTsx=1 applied on vulnerable CPUs, DisableTsx=0 only on fixed CPUs.
✨ IMPROVEMENT CPU-aware C-States: enabled only on AMD dual-CCD X3D (required for core parking), disabled on all other CPUs to eliminate idle state transition latency. Deep C-States visibility in Power Options follows the same rule.
✨ IMPROVEMENT Intel-only tweaks consolidated with CPU detection: TSX enable, Intel hybrid scheduling GUID visibility, HeteroMultiClassParkingEnabled, Intel chipset update. Non-Intel CPUs skip these entirely.
✨ IMPROVEMENT Dynamic tick (bcdedit disabledynamictick) applied on all CPUs except AMD dual-CCD X3D, where dynamic tick must remain active for proper core scheduling.
🪛 FIX BCD x2apicpolicy enable removed (can prevent boot on systems without BIOS x2APIC support — requires CMOS reset to recover).
🪛 FIX BCD pciexpress forcedisable removed (disables ASPM globally — causes data corruption on some NVMe drives and battery drain on laptops).
🪛 FIX BCD useplatformclock no now applied only on Intel CPUs (AMD requires HPET for TSC calibration — avoids stutters/audio crackling on Ryzen).
🪛 FIX DEVICES.cmd: critical devices (System Timer, System CMOS/real time clock, Motherboard resources, ACPI Processor Aggregator) removed from auto-disable list — prevents BSOD/boot failures.
🆕 NEW Core parking and hybrid scheduling tweaks with per-CPU logic.
✨ IMPROVEMENT Per-CPU clock tick scheduling and forced parking request now skipped on AMD dual-CCD X3D — preserves Windows CCD coordination for 3D V-Cache scheduling.
🆕 NEW Auto detect AMD chipsets and install drivers (detects laptop/desktop chipsets, downloads and installs latest version). (Option in Installation)
🆕 NEW UTC hardware clock option for Linux dual-boot (Option in Installation).
🆕 NEW New Program: LexBoosT Hyper-V Manager.
🪛 FIX LexBoosT Packages Manager — Search with multi-word queries now properly quoted (e.g., "visual studio" is treated as a single phrase instead of being split into separate search terms for Winget/Chocolatey).
✨ IMPROVEMENT LexBoosT Packages Manager — Silent mode checkbox added to the update selection dialog (checked by default). Updates can now be installed silently like regular package installations.
✨ IMPROVEMENT LexBoosT Tools Launcher: Better accessibility. Cleaner Launcher.
💥 BREAKING Removing the return of the old Windows 25h2 Start Menu (no longer works).
🆕 NEW File Explorer: remove "Previous Versions" tab from file, folder, and drive property sheets. Cleaner properties dialog.
🆕 NEW Privacy: disable lock screen camera access (NoLockScreenCamera). Prevents camera activation from the lock screen.
✨ IMPROVEMENT Improved LexBoosT Devices Cleanup. Now use DevManView for better accurency.
✨ IMPROVEMENT Scheduled Tasks: Added 21 missing tasks to FINALIZE5.cmd (Disabled instead of Deleted, safer approach).
✨ IMPROVEMENT Services: Reorganized services.yml — sorted alphabetically within each category, grouped by startup type (Automatic/Manual/Disabled), and all services now have descriptive comments aligned to a uniform column for readability.
🪛 FIX PlugPlay service corrected: changed from Manual (3) back to Automatic (2) — critical boot-start service for hardware enumeration.
🪛 FIX ClipSVC duplicate entry removed (was listed twice: change + start, now single change entry).
🪛 FIX TrustedInstaller comment clarified: Manual (3) is the Windows default (trigger-start via WU/DISM), correctly preserved.
🪛 FIX webthreatdefsvc comment clarified: keep Automatic while Defender is active.
🪛 FIX LexBoosT Easy Move User Folders — AppData folder movement was broken (checkbox display name "⚠ AppData" didn't match the dictionary key "AppData"). Fixed by storing the real folder name in CheckBox.Tag. Fixed Documents folder junction point creation by safely deleting only empty subdirectories. Added same-path protection to prevent data loss when source and destination are identical.
✨ IMPROVEMENT BCD Optimizations refactored: all bcdedit commands consolidated into Set-BcdOptimizations function in DEVICES.ps1 with per-CPU conditional logic. Core optimizations (5-level paging off, firstmegabytepolicy UseAll, stale entry cleanup) applied unconditionally. Timer/scheduling optimizations (disabledynamictick yes, useplatformclock/USEplatformtick no on Intel only, tscsyncpolicy enhanced) skipped on AMD 3D V-Cache dual-CCD (>8 cores) to preserve Windows CCD coordination for proper core scheduling.
🪛 FIX APPX-REMOVER.ps1: TokenManipulator kernel handle leak fixed (Marshal.FreeHGlobal → CloseHandle). 32-bit WOW6432Node registry paths added for AppX cleanup. $removedCount now verified before increment.
🪛 FIX APPX-REMOVER.ps1: wildcard path protection added — package cleanup skipped if $packageFamilyName is empty/null. SystemApps path check now rejects junction/symlink targets.
🪛 FIX Set-RegistryValue in DEVICES.ps1: all registry types (DWORD, String, QWORD, MultiString, ExpandString, Binary) now explicitly handled; MultiString values properly cast to [string[]].
🪛 FIX RUNTIMES.ps1: VC++ detection refactored — uses registry view (x64→native, x86→WOW6432Node) instead of fragile DisplayName string matching. Winget install now verified via Test-CommandAvailable. DirectX detection expanded to 6 DLLs, logic relaxed (any DLL found = installed).
🪛 FIX EDGE.ps1: $env:windir="" now wrapped in try/finally — windir restored on all code paths (previously commented out restoration line, left windir empty on early returns).
🪛 FIX DisableCoInstallers warning added: documents that it breaks Realtek/Creative audio drivers and specialty hardware.
🪛 FIX SystemResponsiveness raised from 10 to 14 (safe minimum for audio — prevents crackling on DAC/USB devices).
🪛 FIX DWM FrameLatency lowered from 2 to 1 (reduces input lag from 33ms to 16ms at 60Hz).
🪛 FIX Games task Clock Rate kept at 10000 (gaming benefits), Window Manager Clock Rate lowered to 2000 (avoids CPU overhead).
✨ IMPROVEMENT Disable Find My Device (Disable location-based device tracking by Microsoft).
✨ IMPROVEMENT Disable WAP Push Service (Disable WAP Push Message routing service used for telemetry).
✨ IMPROVEMENT WPAD — disable auto-proxy discovery (prevents MITM attacks)
🪛 FIX The OneDrive uninstall script now finds and deletes all scheduled tasks whose name starts with OneDrive.
✨ IMPROVEMENT Skip the installation of VCredist if they are already installed on the system.
🪛 FIX DEVICES-TWEAKER-AUTO.PS1 — xHCI IMOD was skipped because USB controllers don't have the "Interrupt Management" registry key by default, so they never entered $Devices. C# ApplyImod now called unconditionally (does its own SetupDi detection).
💥 BREAKING Delete Disable Devices in AME. Now you use LexBoosT Devices Cleanup for Enable/Disable devices. (Program updated for this case)
🪛 FIX Intel & Realtek Network Settings: perf keywords (*InterruptModeration, *RSS, *FlowControl, *PacketCoalescing, etc.) now applied on laptops too (were desktop-only). Removed duplicate keys between perf/power blocks. Added missing *PacketCoalescing=0. Fixed *ReceiveBuffers conflict (1024 vs 512), *ModernStandbyWoLMagicPacket prefix, invalid *SSIdleTimeout=0. Settings split: common perf / vendor-specific perf (always) / power management (desktop only).
✨ IMPROVEMENT Update nvidiaProfileInspector to 3.0.1.13
