Microsoft MED-V (Microsoft Enterprise Desktop Virtualization) is a virtualization tool similar to MS Virtual PC, but it allows you to work with virtualized programs “transparently”, i.e. without a window into which another OS is crammed, in which a window of the desired program opens. MED-V will also be able to deploy and manage images for MS VPCs in the enterprise network. Now you can download the beta version, and the release version of MED-V v1.0 will be provided in the Microsoft Desktop Optimization Pack bundle, available for Software Assurance subscribers.
It seems to me that the Sun Virtual Box also has the ability to work "transparently".
To download the MED-V beta, you need to have a Windows Live ID account and you will need to fill out a short questionnaire.

I do not want to build Predictions of myself, but it seems to me that Microsoft, despite the fact that Windows 7 has already performed well in terms of compatibility, is going to radically change the principles of building Windows. In this case, someday there will be a completely different Windows (Unix? Singularity?), For which the built-in virtual machine with the “medvedev” inside will provide compatibility with the old software.
It should be noted that MED-V is being developed for virtualization using only different Windows as a guest OS, like MS VPC, but I have to note that Debian works well in my Virtual PC 2007.
