Is there a way to fix Windows 11 24H2 updates (this time KG5053598) breaking our RDP functionality for remote apps?

This surely will degrade responsiveness of RDP, but the only thing is going to work is to set "Use TCP only" for "Select RDP transport protocols" (located in Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Connections) group policy on server's side, and after applying it perform in elevated PowerShell window restart-service -Name TermService -Force (either reboot the whole server)

Hello,

Try to disable the UDP RDP option for the client by configuring the group policy or the registry key.

1. Group Policy Editor Tweak: • Open the Group Policy Editor and navigate to: • Computer Configuration → Administrative Templates → Windows Components → Remote Desktop Services → Remote Desktop Connection Client • Locate the “Turn Off UDP On Client” setting. • Double-click the setting, select “Enabled,” click “Apply,” then “OK.” • Restart your computer.
2. Registry Editor Adjustment: • Open the Registry Editor and navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client • If the DWORD fClientDisableUDP does not exist, create it by right-clicking in the right panel, selecting New → DWORD (32-bit) Value, and naming it fClientDisableUDP. • Set its value to 1. • Click OK and restart your PC.

Have a nice day.

Best Regards,

Hania Lian
