Windows Optimizer-QA.bat

Windows debloat/optimization script customized for a laptop QA Test Engineer/Devops workflow

Usage

Run as Administrator. Menu:

1. System + user tweaks (default, 10s timeout)
2. User tweaks only
3. Exit

Log: optimus-<computername>.log (script folder)

OS Support

• Windows 11 (build ≥22000) — full support
• Windows 10 (build ≥10240) — full support
• Windows 7 / older — warns and prompts Y/N; AppX/Edge-policy/WindowsAI sections silently no-op (keys/packages don't exist), core service/registry/explorer tweaks still apply

What it does

• Creates a System Restore point (falls back to HKLM/HKCU .reg export if restore fails)
• Chassis-aware: enables hibernation on laptops, disables on desktops
• Restores legacy F8 boot menu
• Tunes pagefile based on installed RAM (skips if ≥32GB, uses auto-managed)
• SvcHost split threshold set per installed RAM
• Sets ~150 non-essential services to manual/disabled, core services forced to auto
• Registry: network throttling off, IRP stack size, shutdown timeout, long path support, telemetry/DiagTrack off, Edge background/ads/telemetry off, Recall off, Office telemetry off
• Removes Copilot, Bing Search app, Widgets (AppX + provisioning, all users)
• Per-user (HKCU + all local profiles + Default profile via hive load/unload): Explorer tweaks, ads/suggestions off, sticky keys off, Office logging off

QA-specific deviations from stock script

Item	Stock	This build	Why
ssh-agent	disabled	left alone	needed for git/test-server SSH
XblAuthManager/XblGameSave/XboxNetApiSvc	manual	disabled	not gaming-focused
Gaming Tweaks menu (option 3, desktop-only HAGS/power-plan/GPU P-state)	present	removed	irrelevant on this laptop; chassis check already no-ops desktop tweaks
WinRM, Hyper-V vmic* services	manual	unchanged	required for automation/VM-based testing
Windows Defender	untouched	untouched	unchanged

Safety

• Admin elevation is auto-requested (UAC prompt)
• Restore point created before any changes; if it fails, registry hives are exported to script folder as .reg backups
• Reboot prompted at end (Y/N, defaults to N after 10s)

Rollback

Import the .reg backups (if created) or use System Restore to the pre-script checkpoint.
