Whitebox

Whitebox cleans junk, finds what's eating your disk, tames startup apps and keeps an eye on your PC, in one fast, native app.

Windows cleaners tend to come with upsells, bundled extras and a habit of phoning home. Whitebox has none of that: no accounts, no telemetry, and the only network call is a daily check for a new version.

It's careful by default. Browser history, cookies and saved passwords are never touched, files in use are skipped, and anything bigger than a cache goes to the Recycle Bin, so it can come back.
