The Microsoft Application Virtualization (App-V) platform is now available for use with the Windows 7 Beta.
"We've been listening to customers who want to see us support Windows 7 early so they can move ahead with their application testing in preparation for their enterprise deployments. Today, we are pleased to announce the immediate availability of App-V 4.5 CU1 for the Windows 7 Beta," said Microsoft in a blog.
Microsoft said: "As you know, we have a high bar for application compatibility between Windows Vista and Windows 7, so you might be wondering why we need an update of App-V specific to Windows 7.
"Application virtualisation is in a small class of applications that have very deep interactions specific to a Windows release - in App-V's case it is redirecting the registry, file-system and component calls. So as we update Windows, we will continue to require new versions of App-V."
All subscribers of the Microsoft Desktop Optimization Pack (MDOP) can register to download the update from Microsoft Connect.
App-V 4.5 CU1 contains a small number of improvements such as instant access or removal of applications assigned to end-users.
