Every tweak is a real setting, and every setting has an undo
22 modules write genuine Windows state — process priority, gaming task scheduling, the power plan, the TCP stack, timer resolution. Each module restores the exact keys it touched, and a System Restore point is taken before the heavy passes. The free tier is the toolbox, not a trial with a countdown.
