This happened after I had to use my PC's 360GB HD I used over two Years ago after my newer 500GB HD had problems and now won't even boot up. Because this 360GB HD is so old and I hadn't used it in so long, I updated it to the newest Windows XP. After that, it seemed to be OK and I even ran Scans with SuperAntiVirus, Malwarebytes and McAfee. Everything seems to be clean now, but that Update message started coming out.
When it first popped up, I would restart the PC to see if it would solve the problem. But, NADA. It says it's installing "1 of 1 Update". It restarts, and that pop up comes out AGAIN!!
Like I said, this 360GB HD is the older one, sometimes the Taskbar doesn't come out when I boot up with it. Maybe that's part of the Problem? I have to use this HD because I can't seem to fix the 500GB HD. And, as I type this........guess what just popped up......yeah...It warns me that it will restart automatically unless I select to restart later...huh....
Anyway, I have Windows XP Media Edition on a Dell XPS PC. Anymore info you need, just ask.
Thanks.
