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Over time, however, the Windows Registry accumulates outdated configuration information and settings, including traces of obsolete programs.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.
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
NOTE: If you have any issues after cleaning your registry with any software, then it is recommended you recover your registry backup file
