I've used CC cleaner for years and aggressively set it to clean most everything except certain web browser folders like cookies and download history.
Also over the years, I've always made sure Restore Point is activated and getting created.
But about 90% of the time I need to restore a Point, the restoration fails. I'm not trying to rollback a windows update. Usually a corrupt profile.
Someone suggested that CC cleaner by default is deleting everything in the user_name\appdata\local\temp folder which is needed to create a usable Restore Point.
Same tech said fine to clean the c:\temp folder or even the c:\windows\temp folder.
