I have used many registry cleaner utilities but no one is merely stand near the perfect optimizer when i start using this amazing cleaner, my computer works like new all the registry related problems are solved i am glad i have such important utility. you should give it a try it,s not free though works much better then ccleaner
I use CC Cleaner and found it works really well but you should always run a couple different programs as one program will never catch all the issues.
