Results vary
Speed, freed space, and usability depend on the device, Windows version, installed software, and the actions selected by the user. Identical results are not guaranteed.
Responsibility for files
Users decide which files to remove or move. Review folder contents and back up important documents before making changes.
Do not delete unfamiliar system files, drivers, work projects, or personal data simply because they use significant space.
Security and faults
If a computer overheats, a drive makes unusual sounds, Windows reports errors, malware is suspected, or important data becomes inaccessible, stop cleanup activity and seek qualified support.
