I just spent way too long helping a friend of my wife with her WinXP box. She said it's gotten significantly slower the past couple of months. She's had it a couple of years. (Must have gotten it when XP was still fairly new.)
I followed the directions on the [link|http://twiki.iwethey.org/twiki/bin/view/Know/WinXPLockdown|WinXPLockdown] page, and after downloading everything -- btw next time I download at work and burn a disk, damn but AOL is slow -- I started installing. Norton started popping up every time I ran another scan. Finally got all the rest installed and Norton turned off. The last of the full-system scans was still running when I left, but it still felt really slow -- 15-20 seconds to open a menu the first time, etc.
How do I identify what's making performance suck so much? I already ran all the scans and only found a few things to nuke. Do I just have to go through the process list and google each of them one-by-one to see if they need to be there?
