Download TweakNow RegCleaner Free for Windows

This excellent freeware utility makes the potentially daunting prospect of cleaning your Windows Registry safe and simple. The interface is spare and straightforward, and most users will probably only need the Scan and Remove buttons.

The settings are configured for immediate use, although you may exclude some Registry branches and references to removable drives from the scan. The default Beginner mode only displays items marked safe to remove, and the Expert mode makes clear which ones aren’t. In case something goes wrong after deletion, you can quickly restore the removed keys.

In our tests, the utility found and removed hundreds of junk entries in minutes, making it a worthy download for almost any home user, especially those who are less technically inclined.
