Free Registry Cleaner is a recently successful application designed to clean the system registry from unnecessary entries. In addition to its main purpose, the tool also offers a quick registry search function, a disk cleaning module for unnecessary files, and process management managers for installed applications on the system and programs running with the Windows state. In addition, the authors have equipped Free Registry Cleaner with the option of creating automatic security copies of deleted entries from the registry, thus enabling their subsequent recovery in the event of possible errors during use of the system.

Free Registry Cleaner also offers the option to exclude scanning of batches of registry indicated by the user.
