Well, I ran the Repair thingy. AND EVERYTHING APPEARS TO BE NORMAL. No more "My Documents" folder within My Documents folder YAY! But Windows after deleting the system files and reinstalling the good ones from the CD, insisted on installing itself.

Why was that necessary? I mean I hadn't uninstalled Windows. It announced at 1 point that Windows would restart in 15 seconds, and I quick took the CD out because I mean, since Windows hadn't been deleted, why would it need the disk to start up? Then I got a screen indicating Windows was about to be installed and setup would complete in about 39 minutes. And there was also an INSERT DISC pop-up that said "insert XP disc and click OK." I hit "Cancel" and got another popup reading:
"FATAL ERROR: An error has been encountered that prevents set-up from continuing. One of the components Windows needs to continue setup could not be installed. Operation cancelled by user." Here I used the X to get that pop-up to go away and boot started. Then an announcement saying Setup was being restarted and to please insert the XP CD.

So I put the XP CD back in and prayed that the process of reinstall in this instance would not end up wiping out all my desktop shortcuts and programs, or change my firewall back to Windows firewall. Or substitute Windows video and sound drivers for the audio and video soundcards I'd added. Clearly I needn't have worried but I never quite feel comfortable with Windows and myself when I attempt cures I've never done before. Too easy to make some innocent mistake and have to reformat and start from scratch. It took me 8-16 hours the last time I had to reformat to get everything back to normal. But the first time is always the scary one. Next time I need to repair, if ever, no problem!

I sure have benefitted from joining Techzonez. Thanks everyone especially moderators!
