These files are used to optimize both booth and application launch times. Prefetch does not preload applications, or any portion of them at boot time. Application prefetch files are referenced only after application launch has been initiated. Checking the last access time stamps on these files will show this to be true. Unused or rarely used entries will have virtually no impact on performance. In any event the folder is self cleaning after 128 entries.The Task Scheduler service MUST be enabled and set to Automatic for proper prefetch operation. Disabling this service can lead to severe performance degradation over time.References: http://home.comcast.net/~SupportCD/XPMyths.html Also check the references on this page.

NOTHING faster than a clean os vs 3+ year old one. there is A HUGE difference no matter anyone says. i been using computers for a long time and build, sell, and fix them. the best tip i can give is reinstall the os fully updated.
