Will this give me more FPS?
It can, but anyone who promises a number is guessing. Q8Booster cuts background contention and applies the settings Windows provides for games. How much that shows up as frames depends on your hardware and your game, so the app measures instead of promising.
Can it get my game account banned?
It never reads or writes any game's memory, files or process, and it injects no code and installs no hooks or kernel driver. Those are what anti-cheat looks for. It only changes Windows settings, with your permission.
What if something goes wrong?
Every change is journaled with its original value before it's applied, so Restore Center can put it back exactly. A change interrupted by a crash or power cut is repaired the next time the app starts. Restoring never needs a licence.
Does it disable Windows Defender or UAC?
No, and it refuses to. Switching off security to make a number look better is what makes most “optimisers” dangerous. Security reports Defender, Firewall, whether this sign-in is an administrator, whether the approval prompt is on, whether the system drive is encrypted, and whether SmartScreen is on. A button opens the Windows page that owns the reading. There is no switch here that weakens any of them.
How often is it updated?
Often. Version 1.0 shipped on 4 September and 1.6 on 13 September. The app checks for a new build when it starts and installs it when you press the button, never while a game is running.
What leaves my PC?
By default, only a licence check: your key and an anonymous device fingerprint. No telemetry unless you opt in. Subtitles and screen reading run on your own processor, and no audio or image leaves the machine.
Why does Windows warn me when I install it?
The installer isn't code-signed yet, so SmartScreen has no publisher record for it. Check the SHA-256 on the download page if you want certainty. The warning goes away once the certificate is in place.
Can I move my licence to another PC?
Yes. A key covers one PC at a time: release it from Account on the old PC and activate it on the new one. Settings can also export your language, appearance and game profiles.
