Of course, the first thing we did to make sure that our Windows XP installation was completely up to date is we turned auto-updates on. One problem with VMs is that if you don't use them for a while, they don't update while their "asleep." So, if you suddenly need on that you haven't used for a while, you might be slowed down by a series of Windows updates that have to take place first before you can safely begin computing. Maybe someone will figure out how to fix that problem. Be sure to check out ZDNet's other Virtual PC 2007 image gallery that shows the VPC '07 user interface.
