Windows 11 may experience issues with Remote Desktop (RDP) connections, such as disconnections, lag, or failure to establish a connection. These problems are often related to the UDP protocol. This article explains how to disable UDP to resolve RDP connection issues.
This method disables UDP connections by modifying the Windows Registry.
Press Windows + R to open the Run dialog.
Type regedit and press Enter.
Navigate to the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client
Right-click and select New > DWORD (32-bit) Value.
Name the new value fClientDisableUDP.
Double-click on it and set the Value Data to 1.
Click OK to save the changes.
Restart your computer.
If your computer is part of a domain environment or you want to use the Local Group Policy Editor, follow this method.
Press Windows + R, type gpedit.msc, and press Enter.
Navigate to the following path:
Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client
Locate the setting Turn Off UDP On Client.
Double-click on it and select Enabled.
Click Apply and OK to save the changes.
Restart your computer.
By using one of these methods, you can disable UDP connections. If your system is part of a domain, using GPO is a more centralized and permanent solution. However, if you are working on a standalone computer, the Registry method will suffice.
Note: After applying these changes, your RDP connections may be slower since they will rely solely on TCP.
