Hi guys you must try this hack in xp.
Warning - changing Registry setting is dangerous and might crash your system. Use the following suggestions on your own risk.
start “Regedit” (if u dont know how then u should’nt be doing this).
Follow this string :-
HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Control -> SessionManager
-> MemoryManagement -> PrefetchParameters.
Then look at the EnablePrefetcher string and change the value from 3 to 5. it doesn’t matter if you keep it Hexadecimal or Decimal.
Close registry and restart WindowsXP; it should load up between 5-15 seconds (or even
more) faster. If u get success spread the word and help others.
Let us all know how you go with your boot up speed mines gone from 30 secs to 8 secs.
Got this from another forum and it works a treat…
