AMUST Registry Cleaner is a system utility designed to help you keep a clean and operational Windows Registry.

Cleaning up the Registry every once in a while is highly recommended, because installing and uninstalling programs may fill it with invalid data, and that may cause your computer to run slow or even crash.

That's why you may find this utility helpful. It can clean up, back-up, or undo cleaning up the Registry very fast. When scanning for problems, the program will search the following categories: Components Subsystem, Internet Explorer, Shared Components, Control Panel, Microsoft Office, File associations, as well as System and User MRU Lists.

After the scanning task completes, you can choose which problems you want repaired and fix them. Keeping a backup of the Registry is always a smart thing to do, because some applications may behave strange after a clean up operation. You can set the program to perform a registry backup before each scan.

Another tool you can use is the 'Registry Compact' tool, which can boost your system performance, is the defragmenting the registry.
Scanning for errors, compacting, and backing up the registry can be scheduled to run whenever you want to.
