Several Windows 11 users have reported that they are having problems connecting to Remote Desktop (RDP) after the installation of 22H2 update. More specifically, they report that they are either unable to connect to the remote computer with error code 0x10b, or the remote connection drops after a while.

The aforementioned remote desktop connection issues do not occur when connecting from computers running Windows 10/8/7, or Windows 11 version 21H2, and this means that they are due to a bug in Windows 11 version 22H2.

This guide contains several methods to fix the following issues with remote desktop on Windows 11 22H2:

• RemoteApp and Desktop Connections hang on «Loading the virtual machine».
• Windows 11 22H2 breaks the Remote Desktop Connection.

How to Fix Windows 11 22H2 Remote Desktop Connection problems.

Method 1. Prevent Remote Desktop Client to connect through UDP.

Remote desktop connection problems in Windows 11 22H2 are due to a bug in the Remote Desktop client (mstsc.exe), which tries to connect to the remote computer over a UDP port instead of TCP. So, the way to solve the problem is to prevent the RDP client from using the UDP protocol to connect to the remote computer and use only the TCP port. To do that, use one of the ways below:

Way 1. Disable UDP Port in RDP Client through Registry.

To disable the UDP protocol in Remote Desktop client using Registry, create the fClientDisableUDP DWORD and set it’s value data to 1 at the following registry location:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client

To do that:

1. Restart the client PC, or terminate the «mstsc.exe» process using Task Manager.

2. Open Command Prompt as Administrator.

3. In command prompt, copy and paste the following command:

REG ADD «HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client» /v fClientDisableUDP /t REG_DWORD /d 1 /f

4. Restart you PC and then try to connect to the remote computer using remote desktop. *

* Note: If you want to undo this change an to re-enable the UDP on RDP on the future, navigate to the above mentioned registry location and delete the fClientDisableUDP DWORD value.

Way 2. Turn Off the UDP Port in RDP in Group Policy.
