By default, Windows does not enable RemoteFX to ensure backward compatibility. However, for optimal performance when using a WebClient RDP, it is recommended that you enable RemoteFX on the server machines that allow it.
To enable RemoteFX on a remote machine, a number of options must be enabled.
Here is the procedure to follow on the remote machine:
Launch the Windows run command Windows+R.
Run:
gpedit.msc
Enable:
Computer Configuration/Administrative Templates/Windows Components/Remote Desktop Services/Remote Desktop Session Host/Remote Session Environment/RemoteFX for Windows Server 2008 R2/Configure RemoteFX
Enable:
Computer Configuration/Administrative Templates/Windows Components/Remote Desktop Services/Remote Desktop Session Host/Remote Session Environment/Enable RemoteFX encoding for RemoteFX clients designed for Windows Server 2008 R2 SP1
Enable:
Computer Configuration/Administrative Templates/Windows Components/Remote Desktop Services/Remote Desktop Session Host/Remote Session Environment/Limit maximum color depth
Restart the remote machine.
