This update applies to Microsoft Virtual PC 2004. You must have a validly licensed copy of Microsoft Virtual PC 2004 installed on your computer in order to install Service Pack 1 for Virtual PC 2004.

Important: You must shut down or turn off all guest operating systems before installing SP1. This ensures that there are no virtual machines in a saved state. This is important because saved states are not compatible between SP1 and all previous versions of Virtual PC 2004.

Service Pack 1 includes an updated version of Virtual Machine Additions. You should update the version of Virtual Machine Additions on all virtual machines where Virtual Machine Additions is installed. For more information, see "Installing Virtual Machine Additions" in Virtual PC Help.
