Wise Registry Cleaner is a freeware tool that lets you clean registry junks, repair Windows errors, and keeps your PC at peak performance.

The Windows registry keeps growing when you use Windows, and the obsolete items get accumulated in the registry, which eventually lead to performance degradation and even system crash. Wise Registry Cleaner incidentally scans the Windows registry and finds errors & residual items in the registry and then cleans or defrags them. By fixing these residual and corrupted items in Windows registry, your system will run faster and more stable.


The Wise Registry Cleaner automatically backed up the Registry before any cleaning is performed. You can use it to restore the registry to the previous point, in case you encounter some system problem. You can also create a full registry backup or system backup manually with this freeware at any time before making any major system or network configuration changes on your PC.

Also when you run this software for the first time, it offers you create a registry backup.

From the main interface, you can set Wise Registry Cleaner to clean the registry on a daily, weekly, monthly, on idle or at log on, schedule according to your own need. Wise Registry Cleaner will automatically clean up the registry in the background when the scheduled time is up.

cleaning-scheduleFrom the settings, you can also create a ‘Clean with 1-click’ icon and place it on the desktop. With this feature, you can clean up the registry by just clicking the icon without opening Wise Registry Cleaner.


Other than cleaning up and defragging the windows registry, the Wise Registry Cleaner can also optimize relevant system settings to improve both system speed and internet speed. After one-click optimization, you will notice some improvement in your PC’s performance.

In the main screen of Wise Registry Cleaner, you can find three types of scanning: fast, deep and custom scan. In ‘fast scan’, the tool will remove only those entries which are safe to delete. The “Deep Scan” is for advanced users and will scan your whole system registry files. In custom, you can specify, which you want to scan and which you want to exclude.

Custom areas of the registry can be scanned for things such as invalid file extensions, obsolete startup program entries, invalid software paths, and more.

Exclusions are allowed, so you can tell Wise Registry Cleaner to avoid cleaning any registry items with specific words in them.
