CCleaner tops our list of free registry cleaners for several good reasons. Besides the fact that it’s completely free and works with all versions of Windows, two other things stand out.
Is it a bad idea to use CCleaner?
First, I've never had CCleaner cause a problem in the Windows registry, which some less well-executed registry repair tools do on a regular basis. And second, because it's optionally available in a portable format (i.e., it doesn't need to be installed).

The latest version of CCleaner works with Windows 11 and Windows 10, as well as older Windows operating systems such as Windows 8 and Windows 7. It also works on all versions of Windows 2008 and 2012 Server.
