Using CCleaner to Clean the Registry

CCleaner also lets you clean the Windows Registry, a database which stores configuration information, hardware and software settings on your system. Every time you alter system configuration information, install software or perform other routine tasks, these changes are reflected and stored in the Windows Registry.

Over time, however, the Windows Registry accumulates outdated configuration information and settings, including traces of obsolete programs. The CCleaner Registry option lets you scan and remove such information, improving the overall function and speed of your system, as well as protecting your digital privacy and security.

TIP: A scan of the Windows Registry should be performed at least monthly, if not weekly.

  • Open CCleaner

  • Click on the Registry tab on the left menu and then click on Scan for Issues

    NOTE:  Advise not to change any of the settings that are ticked unless you are confident with the changes you are making!

  • CCleaner will then perform a scan of your registry and you should then see a list which resembles something like the image below, click on Fix selected Issues… to continue

     

  • As a precautionary measure before you begin fixing the Windows Registry, you will be prompted to save a backup file of your registry. I highly recommend that you let CCleaner do a backup.

    Then if a problem occurs after the Windows Registry has been cleaned, you can restore the Windows Registry to its original state using this backup file.

    So when prompted Do you want to back up the registry before making changes?  Click Yes

    Then for Save As, the default location in Documents and filename should be fine for majority of people, no need to change, click Save to continue

  • Next CCleaner will show you the registry issues where you can either go through one at a time and click on Fix Issue, or the easier way is to click on Fix All Selected Issues

  • Once all your Registry issues are fixed, click Close to complete the cleaning process

    The Windows Registry has now been successfully cleaned

NOTE: If you have any issues after cleaning your registry with any software, then it is recommended you recover your registry backup file
