I check Task Manager many times each day, if there was a misbehaving program or unfamiliar file I would simply get rid of it and fix this problem. But the only cpu hogs I see are web sites...anyway, that's not the problem here, the explorer menus open/find folders very very slowly whether I'm on the internet or not. And that wouldn't explain the very long bootup times I'm experiencing.
The problem with a clean install is the many many hours I'd have to spend re-installing and setting up the many many programs I use. I'm already doing that on a 2nd boot installation on this computer, and eventually I'll reach the point where this corrupted installation becomes moot. But for now, I'd really like to find away to fix the two problems I've mentioned. It would be great to have a boot logging program that lists the boot time for each file as it loads...like XPbootlog, which unfortunately won't run in Windows 2000.
And I'd like be able to figure out what goes on when I try to open a folder and it takes forever...why is it so hard for explorer to find a folder and open it, is explorer.exe corrupted or is there something wrong with the mechanism by which it searches for the folder?
And my original question, can I just re-install Windows 2000 over the existing installation? That would be easy to do if it would still keep all the original associations.
