FAQ

Why is less space freed than the analysis showed?

Files can change after analysis, remain in use or be protected. The final result counts only files actually removed. Close applications and analyze again to inspect what remains. See Troubleshooting.

Can I undo a cleanup?

There is no cleanup undo in SystemCleaner. Review the category explanations and restore needed Recycle Bin files before cleanup. Windows can rebuild caches, but deleted crash dumps and personal files in the Recycle Bin are not restored this way.

Why is the Recycle Bin not selected?

Its contents may still be useful. Selecting it explicitly asks you to confirm permanent deletion. See Cleanup categories.

Why did the program ask to restart as administrator?

You selected a protected location. The existing scan is discarded on restart; analyze again in the elevated session. See Administrator rights.

Why does Windows.old remain?

Some files are protected by Windows beyond ordinary administrator access. SystemCleaner reports those files as not removable.

Why are caches back after cleanup?

Windows and applications recreate caches during normal use. Their reappearance does not mean the previous cleanup failed.
