256986 Description of the Microsoft Windows Registry
If you shut down a computer that is hosting a Microsoft Virtual Server 2005 guest computer, the guest computer state is not saved. For example, the guest computer state is not saved when you shut down the host computer locally, remotely, or by a restart after you apply a software update.
Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To resolve this issue, modify both a Virtual Server 2005 property, and a Windows registry value, on the host computer.
