Is it dangerous? Can I mess up my registry? I don't really want to fix all issues unless I'm pretty much guaranteed it won't mess anything up. It finds the following issues:
Missing Shared DLL
Unused File Extension
Invalid Default Icon
ActiveX/Com Issue
Open With Application Issue
Application Paths Issue
Help File Issue
Installer/Uninstaller Reference Issue
Old Start Menu Key
Missing MUI/Shortcut Reference
When you choose to fix issues you are offered the option to back them up.
If you say yes, you can save them in your documents and then in the unlikely event of there being a problem afterwards, just double-click on the backup and select merge. They will be restored.
OK, I've just done that and everything seems to be OK. Does that mean no damage has been done or after a few reboots can problems start to happen?
ccleaner doesn't as a rule create damage after an issues scan!
I have never had any problems with mine. If you keep your backup for a week or so and then you could delete it if you see no problems (which I doubt you will)
OK thanks for the advice Hazel
