This is an unique technique for XP, which could improve the performance significantly by tweaking the prefetcher. Recommended hardware: PIII 800 or higher, 512M RAM or more.
- run “regedit”;
- goto [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management\PrefetchParameters\EnablePrefetcher];
- Set the value to either 0-Disable, 1-App launch prefetch, 2-Boot Prefetch, 3-Both (“3″ is recommended).
- reboot.

Note: This switch will only work with some programs. Others will return a message saying the program in the target box is invalid. Just remove the switch.
Changing prefetch settings is a bad idea. The default and optimal value for “EnablePrefetcher” is 3. Changing this will impair either boot or application launch times or both. It is based on a flawed understanding of how prefetch works.
