🆕 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 audio-latency.yml: audio endpoint effects disabled on all capture and render devices (AGC/NoiseSuppression via PKEY_AudioEndpoint_Disable_SysFx). Reduces audio processing latency. Effects can be re-enabled per-device in Sound Settings.
✨ 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.

✨ 58 improvements

🆕 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).

✨ 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
