    How to force RDP to use UDP Windows 11?

    I am working on optimizing my RDP connections.

    I want to force RDP to use UDP for most of the traffic.

    In gpedit.msc I have the override to "Use either UDP or TCP".

    When I Wireshark the traffic I only see TCP activity between the host and client.

    Thoughts to force Windows 11 RDP to actually use UDP?

    In theory, max LAN speed is 54 Mbps.

    Can't get UDP to work with RDP 8.0 on Win7 client - Win10 Host


    We (me and a fellow worker) have just started using remote desktop to work. I have been using NetSupport Manager for almost 10 years but just switched to Windows 10 on virtual PC at work and discovered that remote desktop performance with UDP is leaving NetSupport Manager in the dust, performance wise.

    I have opened the UDP port for my PC and use in UDP mode since Friday. I just cloned the virtual PC for my fellow worker and adjusted his user. I connect to this PC and UDP is enabled. But he is on Windows 7 x64 and he is not able to obtain the UDP enabled.

    Yes, he installed the updates for RDP 8.0 and it shows it.

    But UDP is still not working.

    I tried to update to RDP 8.1 but it says this:

    Any idea ? I suggested to upgrade to Windows 10 but I would rather find a solution for Windows 7 since it is supposed to work.

    How to force RDP to use UDP Windows 11?

    Not seeing that option in my Windows 11 or Windows 10.

    So, I did a regedit and added the according DWord and value.

    I can confirm RDP UDP from guest OS Windows 11 to host Windows 10.

    Thoughts to force UDP to third-party clients?

    Playing around with Microsoft RDP app for iOS and Remmina? Did Wireshark and those two seem to be still stuck in TCP.

    I almost have it next to perfect to streaming HD movies, but not quite there yet.
