This policy setting prioritizes the H.264/AVC 444 graphics mode for non-RemoteFX vGPU scenarios. When you use this setting on the RDP server, the server will use H.264/AVC 444 as the codec in an RDP 10 connection where both the client and server can use H.264/AVC 444. Counter Measure: Configure this setting depending on your organizations requirements. Potential Impact: The server will use H.264/AVC 444 as the codec in an RDP 10 connection where both the client and server can use H.264/AVC 444. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Remote Session Environment\Prioritize H.264/AVC 444 graphics mode for Remote Desktop Connections (2) REG: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services!AVC444ModePreferred
