how to optimize windows prefetch?
i have windows XP sp2.
my problem is that whenever i run/execute any program it takes time to start. whenever i delete my prefetch cache the programs start-up faster but after some time they become sluggish!
is there any way i can optimize my prefetch cache?
i found a great article about it here

basically you goto c:\windows\prefetch and delete all the files, the next reboot will be slow. but after that itll be fast =) but after a while itll get slow again.
to fix it open regedit and navigate to the key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
Under this key you should see a value named: EnablePrefetcher
It has 4 possible values:
0 - Disabled : The prefetch system is turned off.
1 - Application : The prefetch only caches applications.
2 - Boot : The prefetch only caches boot system files.
3 - All : The prefetch caches boot, and application files.
set it to 2 and reboot, your boot times will be much faster =)
one draw back is that applications will take slightly longer to start
