Inspect gaming, privacy and maintenance changes. Keep previous values for supported settings and compare the outcome.
Compare PC Tweaker plansMake deliberate changes. Keep what works. Review Windows settings for gaming, privacy and everyday use. See what each tweak changes, save its previous state and restore supported settings when you need to. Start free. No account required.
Optional one-time tip, €1 per coffee. Your download is free. Stripe may show the amount in your local currency.
PC Tweaker installers are code-signed. Our signed Windows installers identify Aurelio Avila as the publisher. Older downloads may be unsigned; check the file's Digital Signatures tab. SmartScreen may still show a warning for a new release.

Changes this website only. The app screenshot stays the same.
Judge a change by repeated runs: frame-time spikes, 1% lows and consistency. Results depend on your hardware, drivers and game. Record the conditions and the previous setting alongside your results.
Use these notes for your baseline and your changed run. Keep conditions comparable and change one setting at a time.
| Check | For both runs |
|---|---|
| Workload | Game and version, scene or benchmark, resolution and graphics settings. |
| System | Windows and driver versions, power mode and background activity. |
| Change | Setting name, previous value, new value and whether restoration is available. |
| Results | Repeated runs: frame times, average FPS, 1% lows and available temperatures. |
Keep a change only when its benefit repeats under comparable conditions. If it makes things worse, restore the supported setting and check the outcome. A health score describes configuration; it does not measure FPS.
See the settings and observations behind your health score, including startup apps, power configuration and security status. It is a configuration summary, not an FPS benchmark.
Compare the facts behind your previous and current scores. When startup apps or settings change, see the difference. When the evidence is unchanged, there is no reason to invent a problem.
Read the registry path, value type and setting written by a tweak. For other operations, inspect the commands involved. Decide with the details in front of you.
Supported settings save their previous state before a change. Restore an individual tweak or review Restore All. Restoring settings does not recover permanently deleted caches or replace a full system backup.
Monitor available temperatures, utilization, VRAM, fan speed and power readings. Unsupported sensors are identified. Use readings during a real workload to understand heat and load together.
Diagnose DPC/ISR latencyInspect your driver inventory and install available updates through Windows Update. Check the device and update details before proceeding; a newer driver is not automatically a faster one.
Use supported hardware controls to balance noise, temperature and power. Review the limits your device exposes and return to its stock profile. Higher limits can mean more heat and noise.
Check CPU, memory, storage and available tweaks. Review your selection before applying changes. An inactive tweak is an option to consider, not proof that your PC is broken.
Review power plans, startup delay and foreground scheduling settings. Compare under the same workload, then retain only the changes that help your machine.
Use Game Sessions to apply a gaming preset when a supported game starts and restore its supported settings afterward. Review hardware scheduling and input options individually.
Compare Game Sessions steeringReview supported advertising, tracking and diagnostic settings. Availability varies by Windows edition. Check password exposure using a hash-prefix lookup; your full password is not sent.
Review privacy and recoveryCompare supported TCP congestion settings and restore the previous configuration. TCP tuning does not control every download on your network or guarantee lower latency in UDP-based games.
On supported dual-die Ryzen X3D processors, inspect the cache topology and test game placement on the cache-equipped die. Single-die chips do not need this adjustment. Compare before keeping it.
Check X3D topology and parkingReview large files, duplicates and supported drive tools. Cleanup explains what can be restored and what is deleted permanently. Removing shader caches can cause rebuilding and temporary stutter.
Adjust file extensions, taskbar options, appearance and other supported interface settings. Choose your app language and theme while keeping the controls close at hand.
The Audio section lists every sound device with the format Windows really uses, then points out what gets in the way. Each change is recorded and can be restored with one click.
Each output and microphone with its connection, sample rate, bit depth and channels, whether effects and spatial sound are on, and whether Equalizer APO, the free third-party equalizer, is active or bypassed.
A Bluetooth headset stuck in call mode because an app is using its microphone. A default microphone that is muted or very quiet. PC Tweaker explains each finding and never changes your microphone on its own.
“Don't lower my game during calls”: by default Windows lowers every other sound by 80% while a call app uses the microphone. “Fix Bluetooth volume control” turns off Absolute Volume when Bluetooth volume does not respond, stays too low or jumps.
Keep HDMI audio or the sound chip awake on mains power, keep USB audio powered, or restart an audio device. Can help when the start of a sound is cut off, you hear a pop, or a device drops out after silence.
Measures how long each driver keeps the processor busy, against Microsoft's limits (DPC 100 µs, ISR 25 µs), grouped by the hardware it serves. A driver past the limit is a suspect, not proven; the check needs administrator approval.
Run a scan and inspect available settings. Note your hardware, game settings and current performance before changing anything.
Read each tweak's effect and trade-offs. Apply your selection; operations that need administrator access request Windows approval.
Repeat the same scene or task under comparable conditions. Look at consistency and frame-time spikes alongside average FPS. Pro adds Game Sessions for repeatable session setup.
Restore supported settings that do not improve your experience. Check the outcome of each restore. Cleanup and repair operations have their own recovery limits.
Windows settings, software removal and driver reviews belong to different workflows. Start with what you need to do.
