I just installed XP SP2 and have noticed a slowdown in
speed, especially during bootup and going from one user
to another user. Is there anything I can do to speed it
back up to where it was before installing SP2?
It can take several days and 3 or 4 reboots for it to speed up. First
defrag. The boot prefetch will kick in after the 3 rd reboot. It takes
several days for the prefetch folder to be rebuilt. And the in built
optimization kicks in every 3 days. After that defrag again. If the
system is still slow after some days try some clean boot troubleshooting
to see what may be hanging up on startup. A program may need to be
uninstalled / reinstalled:
