36 real Windows tweaks — registry, power plan, services, scheduler priorities. Every single one snapshotted before it touches your system. One click to apply. One click to undo.
Numbers below are from our own recorded, published benchmark — same machine, same match type, before and after applying PC Tweaker's gaming preset. No synthetic scores. No cherry-picked peaks.
Before any tweak writes a single registry value, its previous state is captured. Revert one tweak, or all 36 at once with Restore All. This is the entire premise of the app — optimization you can walk back from.
Live CPU / RAM / disk telemetry, plus a list of everything not yet optimized. Fix all of it behind a single UAC prompt.
Scheduler priority, High Performance plan, startup-app delay removal, CPU power throttling off.
HAGS, GPU priority, input-lag reduction — and a Turbo preset that auto-applies when your game launches, auto-reverts when it closes.
Advertising ID, tracking, Cortana, diagnostic data — off. Plus a k-anonymity password breach check.
Duplicate finder by content hash, large-file hunter, S.M.A.R.T. drive health, SSD-safe TRIM. Deletions go to the Recycle Bin — never permanent.
Dark mode, file extensions, taskbar cleanup, transparency off. 5 languages, 12 themes. English by default.
// most "PC optimizers" are theater. // fake progress bars over fake work. We don't sell placebo. Every tweak reads and writes the real registry, the real power plan, the real services — and snapshots the previous value first, full stop. // if it can't be undone, it doesn't ship.
Live system readout — CPU, memory, disk — and a precise list of every optimization not yet active. You see exactly what will change before anything does.
Every selected tweak batches behind a single UAC prompt — not one popup per toggle. Each previous value is snapshotted before it's written.
Game Sessions detects your game launching, applies the Turbo preset automatically, and reverts it the moment you close. Peak state only when it matters.
Changed your mind? Restore one tweak or the entire system to its original state in one click. Cleanup deletions live in the Recycle Bin, not the void.
Every tweak snapshots the original value before changing it, and everything can be reverted — individually or all at once with Restore All. Cleanup operations move files to the Recycle Bin, never delete permanently. That reversibility is the core design constraint of the entire app.
PC Tweaker changes Windows settings only — registry values, power plans, service states. It never touches game files, injects into processes, or modifies memory. It's system configuration, the same category as changing settings in Control Panel.
28 of the 36 tweaks, the Scan, the rollback engine, the RAM cleaner, and the startup manager — free forever, no account needed. Pro (€9.99/month or €59/year) unlocks the advanced set: Turbo Gaming, Game Sessions, duplicate/large file finders, drive optimization, and a few power-user tweaks.
The tweaks themselves never send data anywhere. The optional account exists solely to sync your Pro status between installs. The password breach check uses k-anonymity — your password never leaves your machine in full. The code is open source under MIT; verify it yourself.
The installer isn't Authenticode-signed yet, so SmartScreen shows a warning on first run: click "More info" → "Run anyway". Prefer zero prompts? Install via winget: winget install AurelioAvila.PCTweaker
