TweakNow RegCleaner is almost a must-have tool for Windows that has been installed on your PC for months.

The Windows registry contains application paths, reference directories, uninstall data, programs and actions performed when the operating system starts, improper uninstalls, program flaws, virus passages (even if deleted), etc.

TweakNow RegCleaner digs into the Windows registry to detect errors and problems in each line so that you can safely remove them.

The program itself will warn you of lines that can be safely removed or lines that are more dangerous. Also, TweakNow RegCleaner backs up your registry every time you delete it, so you can undo your changes.
