CPU usage 100% after installing SP2 on XP PRO

[jesuran]

Ive got this issue where after installing just XP PRO, usage was
normal. After upgrading to SP2, usage is always shown as 100% but the
CPU runs fine. No lag or anything like that. Drives seem to be fine,
no problems there. Got any ideas/suggestions, let me know!

Open event viewer & see what/where the problem(s) are in the OS...

I use an old graphic editor called LViewPro v2. And every CPU monitor
will show it pegged when it opens up a graphic file. But no noticeable
performance difference is noted.

I also never had any good luck with the SP2 upgrade. Every computer I
tried it on, always ran slower afterwards. Oddly enough, if you use a
Windows XP install with SP2 included, they work fine.

Hello,

Check which process is hogging the CPU in Task Manager - Processes tab.
