Windows XP Prefetch Parameters Tips

Prefetching (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. This tips allows you to select which components will make use of the prefetch parameters. 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 below. Clear the cache and repeat for each setting.

1. Enter Registry Editor (Run then type regedit then hit Enter button).
2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\Memory Management\PrefetchParameters
3. On right panel, choose 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.
4. Close Registry Editor window and restart your computer.
