On the MDOP blog there is an announcement of new releases of both APP-V (which runs applications in a Virtualized “bubble” so they don’t clash with each other) and MED-V (which runs a centrally managed virtualized OS)
App-V 4.6 can be accessed immediately via MDOP 2010. Existing MDOP customers can download MDOP 2010 at the Microsoft Volume Licensing Site (MVLS). For evaluation, MDOP 2010 can be downloaded from MSDN and TechNet.
App-V 4.6 for RDS (formerly App-V for Terminal Services) is on the Microsoft.com/downloads site.
MED-V 1.0 SP1 Release Candidate is available for immediate download and evaluation from the Microsoft Connect site.
The major points App-V 4.6 is now compatible with 64-bit Windows client and server platforms, enabling IT to take advantage of x64 for client hardware refresh AND also deploy App-V to Windows Server 2008 R2 using remote desktop with scale advantages that come from 64 bit. The springboard site has a Q&A on App-V
MED-V adds support for Windows 7 (32bit and 64bit) – this is what large organizations should be using to deliver similar functionality to XP-Mode but with central management.
