The Windows registry is a database in Windows used to store information your computer needs to run properly. It controls applications, user settings, and hardware devices. The registry is constantly being referenced by programs while they run. The Windows registry is a vital part of Windows. If it's damaged your registry can cause your whole system to become corrupted. Old, unused registry entries can slow down your computer and hurt its performance.

Registry Cleaner scans the Windows registry and finds incorrect or obsolete information in the registry. After Registry Cleaner fixes these problems, your system will run faster and error free. The backup/restore function lets you backup your whole Windows Registry in case you need to go back to the way things were before.
