The software program scans the Registry for various errors like links that are pointing to deleted files, font locations and pretty much everything coming up as an error in the Registry. Those entries that are found are later on displayed in a list. The user can check individual entries or clean them all in one go.

The Registry Cleaner is automatically creating a backup before cleaning the Registry. That way it is possible to restore the Registry to a state before the cleaning took place. The Windows XP and Vista Registry cleaner comes with another option called compact which compacts the Registry to reduce it’s size.

It is recommended to compact the Registry after cleaning it for maximum performance gain. A smaller Registry can reduce system start and overall system performance.

Comodo Registry Cleaner is compatible to Windows XP and Windows Vista and supports both 32-bit and 64-bit editions of the operating systems.
