Some CC selections are obvious to me, but may not be to others. There are some that I *think* I understand, but obviously don't.
So how about making it easy for people to find out?
At the bottom of the Cleaner and Registry sections, add a one-liner explanation of what each item means or does. Tell the user, What does this selection do? What are the implications of cleaning this particular item? What can or can't I do afterwards?
Operation: If I click on, say, Temporary Internet Files, then a one-liner description would appear across at the bottom of the screen.
I am suggesting this because after running CC yesterday, it completely scrambled my custom grouping of icons on my desktop: I am a busy user, so I have about 120 icons in all. Now their groupings are lost, and I have to spend time finding which has gone where.
Which item do I have to uncheck to stop this happening? I haven't a clue, and I can't find it in the online help either.
Assuming you haven't selected any option in the "Cleaner" section which has been unchecked by default I think I'd blame it on the Registry Cleaner.
Long answer short, I'd recommend you don't use the Registry Cleaner unless you are certain about what you are fixing and even if you are, always make a backup.
