CCleaner is one of the most recommended freeware Registry Cleaners available for Windows. However a recent forum post by my MVP colleague and TWCF Mod Ramesh shows that use of CCleaner is likely to break the Windows 7 right click context menu.
Specifically, CCleaner will recommend you delete some registry entries relating to ‘Turn On BitLocker’ context menu for Drives. If you choose to go ahead and delete them, you will find that this context menu item deleted.
BitLocker Drive Encryption is full disk encryption feature of Windows 7 and Windows Vista. It is available in Enterprise and Ultimate editions only. In Windows 7, the feature has been re-invented and offers a handy ‘Turn On BitLocker’ context menu for Drives including USB storage devices.
Some Registry Cleaner programs don’t recognize the valid context menu and wipe the ‘Turn On BitLocker’ menu.
Adds Security MVP & TWCF Mod, Corrine :
The current version of CCleaner is v 2.23.993 but I just tested it on Windows 7 with the same results. I also don’t recall all registry items being pre-checked in the past with CCleaner. You will find that registry cleaners are not recommended by security experts on the well-known security forums. We have seen registry cleaners do much more damage than good.
Nevertheless, if you have used CCleaner and find that your ‘Turn On BitLocker’ context menu item has gone missing, you can download this registry fix by Ramesh and apply it.
So how safe really are, Registry Optimizers & Cleaners, in general? We have a discussion going on here. What do you feel? Do you use any? Feel free to comment below or at the forum thread.
UPDATE: The problem appears to have been fixed in its latest version.
