When I open Windows Explorer it uses up all CPU

And ?
What OS?
Does it settle down to normal levels once windows has fully loaded?
Have you made any recent changes?

Windows XP, SP3. On an older (2002) Gateway Laptop. I have not downloaded any software lately, except Norton PC Checkup--which found nothing on my computer causing problems. I have run Malware and the full Norton virus check. Nothing shows problems.

Whenever I open Windows Explorer, it uses 85-95% CPU, essentially using all CPU as other programs need some. This started just recently, but weeks after I downloaded Norton PC Checkup.

Norton + XP = WORLD OF HURT!!

Serious dump that as your FIRST option..

There's some useful maintenance tips here: https://www.askmehelpdesk.com/comput...rs-233870.html

Slightly out of date, but you get the idea..

PC checkup is a total cpu/memory hog. Curlyben is right

I use this disk optimizer which runs in background, and perfect for older pc's
