Ok, I've been using this for about a month now and it works pretty well. It has its problems, but for making your system run faster, you can't beat it with a stick.
Its called GameBooster by iobit and I have come to use it constantly as I'm sure you will also.
It closes all the processes you don't need before you start your FS. When your done, it turns them all back on.
