Vista - Microsoft pushes business users to start Windows 7 upgrades now.

Windows 7’s consumer launch is just over a month away. But there’s no reason business users should delay their Windows 7 deployment plans, according to the company.
To accentuate its point, Microsoft is rolling out the new version of the Microsoft Desktop Optimization Pack (MDOP) — a bunch of deployment-focused tools available to its volume licensees with Software Assurance contracts — months earlier than expected. Instead of holding up the new MDOP release until early 2010, as it originally planned, Microsoft is going to ship MDOP 2009 R2 at the end of October 2009 and then provide the updated MED-V virtualization tool to business users via a service pack once it is available in early 2010.
(MED-V is the application-virtualization software based on the Kidaro technology Microsoft acquired in 2008.)
