FAQ
Will cleanup make Windows faster?
It can help when the C drive is nearly full, but cleanup is mainly about restoring free space and update reliability.
Should I use one-click cleanup?
Use review-first cleanup. One-click deletion is risky if it includes Downloads, personal folders, browser profiles, or system components.
