Point.

I found what happened:
http://msdn.microsoft.com/en-us/library/windows/desktop/dn302074%28v=vs.85%29.aspx

Given that we are unable to provide and change manifests on the fly for
thousands of executables, we will have to hack our way along in future
because all upcoming versions of Windows will return a wrong OS version
number.

Why isn't there at least an additional non-manifest way to claim
compatibility with the current OS? :(
