See my point below about ALPN. You need to advertise support for HTTP/2 in the TLS ClientHello and this logic is contained (on a Microsoft platform) in schannel.dll.
Microsoft first added ALPN to SChannel in 8.1 and RARELY updates this library outside of OS releases, so that's (at least one reason) why you won't see on Windows 8/2012 Server.
