Microsoft Windows OS will create a new registry entry for every new program you install. The entry may contain the path to shared DLL, dependent components, license information, browser objects, etc.

If you uninstall the program, the OS may not remove its corresponding registry entry. As the time passes by, you may install and remove a lot of applications and the registry will have a lot of orphan entries due to which the computer’s performance will degrade.

This happens because the OS will process each and every entry in the registry. When it finds an orphan entry, the OS will not be able to process it. Thus, time is wasted by the OS in finding and processing it.

To prevent this issue, Windows registry should be optimized on a regular basis. A free program that allows you to do the same is Wise Registry Cleaner, a small application that allows you to defragment the Windows registry and remove orphan entries from it.

Once you install and run it, Wise Cleaner will recommend you to back up the Windows registry. The program has a function for the same. The backup will be saved to an unknown location of your computer in a compressed file. You don’t have to search for the backup. Restore option in Wise Reg Cleaner will display a list of backups and it allows you to restore or remove the same.

Wise Registry Cleaner features the below 3 tools:

Deep Scan: This function in Wise Cleaner will check each and every entry in the registry. It functions in the same way as the fast scan tool.
