Hi, My suggestion is to handle the case when the newer OS will be installed in the guest as well.
Please look at version helper API - http://msdn.microsoft.com/en-us/library/windows/desktop/dn424972(v=vs.85).aspx <http://msdn.microsoft.com/en-us/library/windows/desktop/dn424972(v=vs.85).aspx> and keep in mind that the usual GetVersion and GetVersionEx (that returned major, minor versions and build number) will be deprecated or changed after Windows 8.1.
