App-V : Updated OS VALUE XML Tag References and Supported Client Versions
I was trying to test applications that were sequenced for windows XP on Windows 7 . The problem was that I needed to update the OS VALUE XML in the config file .
I came across an article from Steve Thomas , Senior Support Escalation Engineer at Microsoft with a great list of OS VALUE XML tags linked to the operating systems witch I have used below. You can see the full post at : http://blogs.technet.com/softgrid/archive/2009/10/29/updated-os-value-xml-tag-reference-and-supported-client-versions.aspx
The following table lists the supported OS VALUE element options and the minimum supported client versions for Microsoft SoftGrid and Microsoft Application Virtualization. This element defines the required operating system. If there are more than one OS element in a particular IMPLEMENTATION tag, it is implied that the software package works with each. If none are present then it is assumed to run on all operating systems:

Hope it helps ,
