Use borderless fullscreen windows; exclusive fullscreen is not supported.
Remote Apps supports borderless fullscreen windows. In a game’s or application’s display settings, choose Borderless, Fullscreen windowed, or the equivalent option. The application remains a window that can be captured and presented through Apps.
Exclusive fullscreen is not supported. In this mode, the application takes exclusive control of the display through its swap chain instead of behaving as a composited desktop window. If entering fullscreen loses the image or produces unexpected behavior, return to windowed or borderless mode.
Maximizing an ordinary window is different from fullscreen: maximizing respects the taskbar’s working area. See Integration.
