Clean Prefetch Data (To Increase Speed)

The prefetch directory can get full of junk and obsolete links which can slow down your
computer noticeably. I would suggest that you do this once a month or so to improve the
speed. Do not follow this on a daily basis as prefetching of most commonly used programs
will speed up the execution of those programs. To perform this trick go to
C:\windows\prefetch, and delete everything and reboot.
