EzRegistryCleaner enables you to take a back-up of the computer registry before fixing it. As soon as your current registry is scanned and Ezregistrycleaner displays you the diagnostic results, the back-up will be made automatically.
Please see General Settings for more information regarding automatic registry back-up.
At any point you could restore a computer registry settings to an earlier date. Simply click on the Restore tab on the navigation -panel to show you a list of back-up data files available for restoration.
