I have tried almost all of the system utility programs, and there have only been a couple that I actually liked. Personally I do use Registry Mechanic, but I also used Fix-It Utilities for a while. The one main aspect I love about Fix-It Utilities is the user interface, it is extremely easy to use and navigate through. Now some of the other ones you would probably need a treasure map in order to find where you would need to go just to clean out your hard drive, and on here it is not like that at all. Some of my favorite utilies that Fix-It offers, that  I feel are superior to other programs are the  Internet optimizer and  the hard drive cleaner. All in all, I feel this is absolutely great program and out of all the utility program it is the easiest to navigate through.
