I just got done installing Vista x86 SP1 via DVD. After the install, the first thing I did was run microsoft update. After the updates, the computer went through configuration stages 1-3 as expected and rebooted. Once it rebooted, it went back to the configuration stage 3 screen and finished to 100%, again as respected, but then rebooted again. It then continued this cycle, always returning to configuration stage 3 then rebooting. Since I just got done installing, I decided to reinstall and try again just to see if it was a fluke. Same thing. So now I reinstalled again but didn't do updates. I am betting it probably has to do with the latest cumulative security updates, but I really have no idea. I am probably going to try the updates again minus anything recent and then try to install each of the new ones manually to try to narrow it down. Any thoughts? Thanks for your time.
