When I'm going from fullscreen to windowed mode in XNA the window does not use the default windows theme but the old "non-aero" style. I'm using Windows 8, don't know the new terms for the different themes.
I tried this solution: XNA losing title bar theme on fullscreen->windowed transition, but it doesn't seem to work, at least not on Windows 8.
How do I make sure the default theme is always used? Doesn't have to be a XNA specific solution.
