How To ALter Prefetch parameters

**************************************************************************

Pre-fetching (the reading of system boot files into a cache for faster loading) is a
commonly overlooked component that can have a significant impact on system boot
time.

To see which files are gathered using each setting, clear the prefetch cache
located at C:\Windows\Prefetch and then enable one of the settings listed in this hack.
Clear the cache and repeat for each setting.

Set the Registry key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\
Memory Management\PrefetchParameters\EnablePrefetcher to 0 to disable
prefetching, 1 to prefetch application launch files, 2 to prefetch boot files, or 3 to
prefetch as many files as possible.
