XP Pro SP2, Intel 3.3 cpu, 1 gig ram. My automatic updating stopped working. I had it set to notify me of new updates, and I downloaded and installed what I wanted. Now I get no notifications. If I go to the Windows download site the option I select is download critical updates. This brings up a window telling me that my computer is being checked to see if all the needed files for downloading are on my machine. I am told that they are missing and that I can download and install them by clicking on the provided button. I then see messages saying that the download is progressing, and when I get to 100% a new message tells me that the files are being registered. So far so good. Unfortunately, I am returned to the window saying my computer must be checked, and we go around again. In my investigations to date, the only suggestion I found (in several places) is update my display driver. I have not yet done so because my screen presents no problems. Anybody out there have experience with something like this? Thanks. esmo
