The program will speed up your computer, prevent crashes and generally does a good job in tuning up your computer. It has all sorts of helpful features. But I found out that instead of fixing shortcuts, it removed a lot of them causing me a lot of work in replacing them. So if you are going to use that program, do yourself a favor and uncheck the fix shortcuts option. I removed the program from my system to avoid coming up with anymore unpleasant surprises.
