I have been using Registry Patrol since 2007 but I have never experienced the problems you are having. Here's the key, I have used every registry program there is and I finally figured out that, you need to very careful about what you let the program take out. After using System Mechanic my computer crashed and I lost everything because of failing to back up.Although making it sound as though a child can use them, these programs need to be used by someone with an amount of computer savvy because they are basically all the same.
