Prefetch Applications to make them load quicker

If you have lots of RAM like I do then you can prefetch a number of applications by using the /prefetch:1 switch. This will load the application into your RAM for MUCH faster startup times. Be careful on how many programs you do this with because it'll eat up your RAM if you do it too much.
