Every change we make, listed before you pay
The reason PC optimizers have the reputation they do is that almost none of them will tell you what they actually change. A tool that rewrites your system but hides which settings it touched — or cannot put them back — is asking for trust it has not earned. So here is the entire catalogue: all 127 optimizations, what each one does, and which ones cost you something.
Nothing hidden
All 127 listed here, free and paid alike.
All reversible
Every tweak can be rolled back individually.
Outside your games
No injection, no game files touched.

24 of these are free
You can apply them, measure the difference on your own hardware, and roll them back if you disagree — before deciding whether the remaining 103 are worth paying for. Most of what is here you could also do by hand; our guides explain how. What the tool adds is doing it in one click and putting it back after every Windows update.
