CleanGeek clears the caches, temporary files and Windows Update leftovers that build up on a Windows PC, and shows you what is installed and what starts up with the machine.
Two steps, always. Scanning measures and changes nothing; cleaning removes only what you have ticked. Nothing is ticked for you except caches and temporary files, and every item says in plain English what it is, what you lose, and whether it rebuilds itself.
There is no registry cleaner. That is deliberate - it is the part of every other cleaner that breaks machines and has never been shown to make one faster.
No telemetry, no account, no bundled offers, no paid tier. GPL-3.0 open source.
Requires Windows 10 or 11 (64-bit). Self-contained installer, .NET 8 bundled.
