@dragonmew : Programs can be somewhat be very similar to IOBit, but I do think that some other programs are better developed than it. You should always use these types of programs with caution. CCEnhancer has never messed up anyone's system, I've checked for reports around the web and have seen nothing.
You seem to be the only one having issues with programs that others aren't. There might be some other factors that come into play if you're the only one having the issues, but you honestly can't expect everything to be perfect.
I can still only recommend CCleaner + CCEnhancer because it is one of the safest options available. The program cleans only what is necessary, you really don't need all of those tweaks that IOBit has that claims to speedup your PC.
It's always smart to make backups of everything, so you can restore everything with ease if something happens to go wrong.
