I use VPC with Windows 2000 on an almost daily basis. It works great. Well as you know, MS released some security updates to Windows, so of course, I downloaded them. Once windows did it's restart, it went into an infinite loop of restarts. I wathced windows restart over and over and over again. I finally had to "pull the plug" on it so to speak. After doing so, I started it up, and now it appears to be running as expected, but I wanted to give a warning to people to remind you to back up before applying this update.
