Microsoft Enterprise Desktop Virtualization (MED-V), is a component of the Microsoft Desktop Optimization Pack (MDOP) for Software Assurance customers. It allows administrators to provide a virtualized desktop image to users and manage them from a central console. The upcoming Service Pack 1 for MED-V will expand support for Windows 7 (both 32 and 64-bit) as a host platform. Considering most large companies held off on upgrading to Windows Vista and opted to wait for Windows 7, this technology will help boost the migration since they can do so and run older programs that may no longer be supported or have not been certified for Windows 7.
In V1 SP1, MED-V continues to employ Virtual PC 2007 as the virtualization engine but unlike the consumer “Windows XP Mode” it does not require hardware-assisted virtualization like Intel VT or an AMD-V to be present in the processor. This allows even those with lower end or older processors to take advantage of enterprise desktop virtualization.
Microsoft has put together a screencast demonstrating running a MED-V workspace using a V1 SP1 client in the Windows 7 environment.
