The COMODO Registry Cleaner was designed to be a tool developed to fix errors and optimize the performance of the Windows registry. This tool is very careful with the registry and never deletes a registry entry if this could harm your system. For safety reasons, COMODO Registry Cleaner makes automatic backup before cleaning the registry entries.

COMODO Registry Cleaner removes items from the Windows Registry which are no longer in use or are unwanted on the system. Such items may include information left by software that has otherwise been removed from the computer. It is possible that these persistent items may interfere with performance or have other negative impacts.
