1.3.3 Enhanced RemoteApp
Enhanced RemoteApp is a graphics presentation mode supported by RDP 8.1 that leverages the Remote Desktop Protocol: Graphics Pipeline Extension ([MS-RDPEGFX] section 1.3) to remote only the contents of the windows running in a RAIL session (see [MS-RDPEGFX] section 1.5 for implementation requirements). This implies that the desktop background is not remoted and a client that supports Enhanced RemoteApp will always have access to the complete contents of a RAIL window, even if the window is obscured on the server.
