I don't know about this specific package, but I'm distrustful of any software that promises to make things better with a button click. I've never seen them make things better, but I have seen them make things worse, even from respected companies.
Good default action for a modern O/S is to do nothing. They do a pretty good job of taking care of themselves. If you run into problems, or think there's a way to make it better, do it manually. That way you know what's going on, and can fix it if you screw something up.
