I have Windows XP Professional with SP1. When I run a Windows update, the Express Install and Custom Install screen is display. No matter which, option I choose, the next screen displays "Windows Update is looking for available updates" with the green bar moving from left to right. The PC sticks on this screen, constantly searching I presume. I updated to SP2 (from a CD), then ran a Windows Update, which gives the same results. Any views/solutions anyone?
