Kleaner for Windows

Kleaner scans your drives, explains what takes up the space and cleans what is safe: caches, temporary files, leftovers of uninstalled programs and old project folders. Every large file and folder gets a verdict (safe to clean, clean with its own tool, uninstall, breaks something, your files, system or unknown) saying what it is and what happens if you delete it. With no rule, the verdict is "unknown": Kleaner never guesses.

Your own files only go to the Recycle Bin and can be restored from the log. Permanent deletion is limited to a public list of caches, nothing is ticked in advance, and you can preview the exact list of files before cleaning. It also handles duplicates, startup programs, broken shortcuts, preinstalled apps (for your account only), a read-only health check-up and a restore point before heavy cleanups.

No telemetry, no account, no ads, and it never cleans the registry. Available in 8 languages, as a portable exe, an installer or via Scoop.
