The CCleaner Professional Registry section is devoted to verify the integrity of Windows Registry, the file containing the system configuration. CCleaner Professional scans the registry for more than a dozen types of errors and provides the ability to save a backup copy before carrying out a repair.

CCleaner Professional’s tool menu contains more specific utilities, such as a quick uninstaller, a list of the programs that start when you launch Windows, and a restore point manager.

Unlike the free version, CCleaner Professional includes automatic updates and monitoring functions that allow you improve your system in real time by eliminating unnecessary files, cleaning the cache, or deleting temporary files. Also, you can decide whether you want to be notified prior to deletion or let CCleaner Professional take care of everything automatically.
