The gamer's ultimate Windows 11 tune-up & repair kit — by Carl Prewitt Jr.

---

You just got a new gaming PC. You built it, or you tore it out of the box. And before you've even installed your first game, you're staring down the same chore every single time: rip out the pre-installed bloatware, shut off the telemetry and the AI nagging, kill the junk background services that cause stutter, tune the network so your shots actually register, flip on the performance power plan, check your RAM is running its XMP/EXPO profile... an hour or two of tedious, error-prone clicking before the machine is actually yours.

PitCrew does all of it in one window — and when something breaks six months later, it turns into your own diagnostic bay: it reads your crash logs, decodes your blue screens into plain English, checks your drive health, and fixes stuck Windows Update, all without you touching a command line.

It's built for gamers, but it's genuinely for everyone. And every single thing it does is reversible — it starts in a safe simulation mode, backs your system up before it touches anything, and can undo its own changes with one click.

What it does

🧹 Debloat	Strip preloaded junk (TikTok, promos, Copilot/Recall, legacy apps) at the system-image level so it stays gone.
🎯 Tune for gaming	Nagle's Algorithm off, RSS/RSC tuned, network throttle removed, "Ultimate Performance" power plan unlocked.
🩺 Diagnose	One read-only scan with a plain-English verdict: crash history, blue-screen decode, drive SMART health, and whether your RAM's XMP/EXPO is actually on.
🔧 Repair	Repair corrupted Windows files (DISM + SFC), find & fix disk errors (chkdsk), reclaim GB with a deep clean, reset a broken Windows Update, back up all your drivers, and a Safe-Mode cleanup cycle.
↩️ Undo anything	Restore point + registry backups before every run, and a one-click Undo Last Live Run.

Two profiles out of the box — Hardcore Gamer (maximum aggression) and Standard User (keeps everyday features) — and you can check or uncheck any individual item before you run it.

Quick start

1. Download the latest PitCrew-vX.Y.Z.zip from the Releases page. No installer bloat, no compiling — it's ready to run.
2. Right-click the ZIP → Properties → check "Unblock" → OK, then extract it anywhere. (Windows marks files downloaded from the internet; unblocking once saves you clicks later.)
3. Double-click Install-PitCrew.cmd to add Desktop + Start-Menu shortcuts — or just double-click Launch-PitCrew.cmd to run it right out of the folder.
4. Accept the UAC prompt. PitCrew needs administrator rights to change services and system settings. It asks once, at launch.
5. It opens in DRY RUN. Pick a profile, look over the pre-checked items, hit Execute Selected, and read the console. Nothing has changed yet — dry run only simulates.
6. Happy with the plan? Flip the DRY RUN switch off and run it for real. Changed your mind afterward? Undo Last Live Run.

Works on the PowerShell that's already built into Windows 11 (5.1) and on PowerShell 7. No runtime to install.

Your safety net

PitCrew is a power tool, so it's built like one — with guardrails on every edge:

• Dry run is the default. Your first click simulates and logs every would-be change with its current value. You decide when to go live.
• It backs up before it touches anything. Every live run creates a Windows System Restore point and exports the affected registry areas as .reg files into Backups\.
• One-click undo. Every registry value, service, scheduled task, network setting, power plan, boot flag, and file it changes is recorded — Undo Last Live Run replays it all in reverse.
• Critical things are protected in code. Windows Defender, the Store, Xbox/Game Pass, your GPU/audio drivers, codecs, and core system services cannot be removed or disabled, no matter what — the protection is hard-coded, not a setting.
• Nothing is hidden. No compiled .exe, no bundled third-party programs, no silent downloads. It's all plain-text PowerShell you (or anyone) can read.

⚠️ Please read this before you flip off Dry Run

The honest version: PitCrew is built so it won't break your PC — everything is reversible, critical components are protected, and it never deletes your personal files. But it does change real Windows settings, and if you turn something off without knowing what it is, you might surprise yourself. Here's the stuff worth knowing:

• Your antivirus or Windows SmartScreen might warn you about it — that's expected. PitCrew is an unsigned PowerShell tool that edits the registry, disables services, and can touch boot settings. Security software watches for exactly those behaviors, so it may show an "unknown publisher" notice or a caution flag. That does not mean it's malware — the entire source is right here for you (or your techy friend) to read. If Windows blocks it, click More info → Run anyway, or unblock the ZIP as described in Quick Start.
• Some toggles change how your PC behaves (all reversible): turning off Print Spooler stops printing until you undo it; turning off Windows Search makes file search slower; removing an app you actually use means reinstalling it (free) from the Store. Read each item's description — they're written in plain English and flagged with warnings where it matters.
• On a laptop, the "Ultimate Performance" power plan trades battery life for speed. Great on a desktop; expect more heat and drain on a laptop.
• The Safe-Mode and recovery features are the advanced corner. They reboot your PC (save your work first) and are meant for fixing a sick machine. They're designed to return you to a normal boot automatically — but if you're not sure what Safe Mode is, leave those for when you actually need them, or have someone who knows walk you through it.
• Good habit, not PitCrew-specific: keep your important files backed up. You should anyway. 🙂

Bottom line: start in Dry Run, read the descriptions, and you're on safe ground. The guardrails are there precisely so a first-timer can explore without wrecking anything.

Feature tour

🧹 Debloat & Telemetry

• Removes preloaded apps at the provisioned-image level (Remove-AppxProvisionedPackage), so a bloat app doesn't silently reappear when Windows creates a new user profile.
• Suppresses diagnostic telemetry, the advertising ID, app-suggestion re-installs, Copilot, and Recall via the same enterprise Group-Policy keys IT departments use.
• Disables the Compatibility Appraiser and CEIP scheduled tasks that spike your disk at idle.
• Forces Game Mode on and (Hardcore profile) turns off the Xbox Game Bar overlay and background recording — a known cause of input lag and V-Sync conflicts.
• Hardens background services (DiagTrack, Windows Search, Print Spooler, MapsBroker, Bluetooth Audio Gateway, Remote Registry) with the live state of each shown right on the row.

🎯 Network & OS Tuning

• Nagle's Algorithm off on every active adapter — small packets (your inputs) send instantly instead of being batched, killing up to 300 ms of artificial delay.
• RSC off / RSS on, TCP receive auto-tuning to Normal, and the network throttling index cap removed.
• DNS flush and an opt-in Winsock reset for a clean network stack.
• Unlocks Windows' hidden "Ultimate Performance" power plan so your CPU stops downclocking between frames. Undo restores your previous plan and deletes the copy.

🩺 Diagnostics & Repair

Diagnose:

• Run Full Scan (read-only, changes nothing) — leads with a plain-English "what to do next" verdict, then: stability events (unexpected reboots, service and app crashes), blue-screen bugcheck codes decoded into plain English with a likely cause (GPU / RAM / driver / hardware) — no debugger download required — plus DCOM 10016 events, drive SMART health, and per-stick RAM speed vs rated so you instantly see if XMP/EXPO is off.
• Check Disk — a safe online chkdsk /scan for file-system errors (no reboot).

Repair & clean:

• Repair System Files — one button runs DISM /RestoreHealth then SFC /scannow, the canonical fix for a corrupted Windows. It only restores known-good files; it never deletes your data.
• Schedule Disk Repair — sets a full chkdsk /f /r to run on next reboot for deeper file-system and bad-sector repair.
• Deep Clean — reclaims real GB the safe way: Windows component-store cleanup, update and Delivery-Optimization caches, and Windows.old if present. Never touches your documents, downloads, or Recycle Bin. No snake-oil registry cleaner — those give no real benefit on modern Windows and risk breaking things.
• Reset Windows Update — the standard fix for stuck updates, fully reversible.
• Back Up All Drivers — pnputil export of every third-party driver so a reformat doesn't leave you hunting for chipset and network drivers.

🔧 WinRE & Offline

• Safe-Mode repair cycle — clears locked temp files and runs an integrity check from Safe Mode, then returns you to normal Windows. It uses a self-deleting launcher and removes its own boot flag first, so a normal boot is guaranteed.
• Temp & cache purge — transient locations only, never your documents or Recycle Bin.
• Recovery-image backup, WinPE prerequisite check, and a transparent, undoable post-format hook.

For PC repair techs (and anyone charging for a fix)

PitCrew is MIT licensed, which means you can use it commercially — including running it on clients' machines as part of a paid cleanup, tune-up, or repair service. That's exactly what it's good at: walk into a job, run a Full Scan to show the customer what's wrong, debloat and tune in one pass, and hand back a faster machine — with a restore point in place if they ever want to revert. The tool is free and open; your time and expertise are what you charge for.

How it's built (why you can trust it)

• 100% PowerShell + a WPF interface. No compiled code to hide behind — what you see is what runs.
• Config-driven. Every app, tweak, and service it targets lives in readable Config\*.json files, not buried in code.
• Native tools only. It calls tools that already ship with Windows (pnputil, bcdedit, reagentc, sfc, netsh, powercfg, reg). It downloads nothing.
• Layered structure: Run-Suite.ps1 (the shell) → Modules\*.psm1 (the logic) → Config\*.json (the targets). Read any layer top to bottom.

FAQ

Is it safe for a normal, non-technical person? Yes, with common sense: leave Dry Run on for your first pass, read the item descriptions, and stick to a profile's defaults. Nothing it does is permanent or unprotected. The one area to be cautious with is the Safe-Mode / recovery tab — that's for fixing a broken PC, not everyday use.

Will it delete my games, files, or documents? No. It targets Windows bloat, settings, services, and temp/cache files only. Your personal data, games, and installed programs are never touched.

My antivirus flagged it. Is it a virus? No. See the warning section above — security software reacts to any tool that edits the registry and services, which is most of what a tune-up tool does. The source is fully readable; nothing is downloaded or hidden.

Can I undo everything? System tweaks, services, network settings, the power plan, and boot flags: yes, via Undo Last Live Run. Removed Store apps come back with a free Store reinstall (Windows has no reliable API to restore them in place). A Winsock reset is the one clearly-flagged exception that a reboot finalizes.

Does it work on Windows 10? It's built and tested for Windows 11. Much of it will work on Windows 10, but that isn't officially supported.

Requirements

• Windows 11 (64-bit)
• Administrator access (it asks at launch)
• PowerShell 5.1 (built into Windows) or PowerShell 7
