Hi, I have been getting tons of complaints today about user's PC's restarting out of the blue today at my work. They say that it just restarted for no reason. Well, I downloaded the Intel monitor prog. to see if the temps were over... and they were fine. Finally, I remembered yesterday that my pc's at home all download like 6 windows critical updates yesterday and checked out the windows update on the user's pcs. It turns out that since we have automatic updating turned on, and it is set to do it at random times during the day for each person, that the update that they were getting automatically restarts the computer, no questions asked about IF you want to shut down, it just does it. I mean, it usually at leasts asks if you want to restart the computer. I have had people say that they got up to go get some coffee and came back and the computer was restarted. This is the first time I have ever seen it do this and it is a major pain. Has anyone else had this problem today or yesterday?? Microsoft should be ashamed. All the PC's are XP Pro SP1 and a few are 2000Pro SP4.
