another way to tweak boot time

*Warning* - Changing Registry setting is tricky and could crash your system. Use the following tweak at your own risk, always back up first before modifying anything in the Registry.

Start , run, type "Regedit"

Follow this string :-
HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Control -> SessionManager -> MemoryManagement -> PrefetchParameters.

Then look at the Prefetch 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.

*Tip - run bootvis and record the boot time before applying this tweak.
