A comment, if not a solution
1) Metro apps suck mooseballs.
2) RDP worlks just fine, but Local windows 7x maching thinks it's some kind of app that, even in full screen mode, when I mouse to the edge the whole RDP desktop 'slides' to one side, and Windows 8.1 on the local computer peeks it's head out from behind. Fail.
Maybe there's a way to turn that off, but WTF- I don't have an (another) hour to chase it down.
Not at all helpful to you, thank you for letting me vent.
