Remote Desktop is a feature that allows you to access and control other computers remotely through the internet network. This feature is very useful for various purposes, such as working from home, providing technical assistance, or managing servers.
However, some Windows 11 users are experiencing issues with Remote Desktop after updating the operating system. This issue causes Remote Desktop to not connect or to disconnect unexpectedly.
In this article, we will explain what causes Remote Desktop issues on Windows 11 and how to solve them. We’ll also give you some tips to improve Remote Desktop performance and security. Keep reading this article until the end to find out more.
What Causes Remote Desktop Issues on Windows 11?
Before we understand how to solve Remote Desktop issues, it is important to know what factors can cause this problem. Some common reasons include:
- Incorrect Network Configuration: Improper network configuration can be at the root of the problem. This includes incorrect firewall settings or changes to the router.
- Incomplete System Update: If the Windows 11 22H2 update is not installed correctly, it may affect Remote Desktop functionality.
- Outdated Device Drivers: Outdated hardware drivers or incompatible with Windows 11 22H2 can cause issues.
- Application Compatibility Issues: Some third-party applications may not be compatible with Windows updates, which can interfere with Remote Desktop.
According to Microsoft, the Remote Desktop issue on Windows 11 was caused by a bug in the Remote Desktop client that made it only try UDP connections and not try TCP connections. UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) are two protocols used to send data over a network. UDP is faster but less reliable, whereas TCP is slower but more reliable.
UDP connections are typically used to send audio and video data that require high speeds, while TCP connections are used to send text data and commands that require high reliability. If a UDP connection fails or is blocked by the firewall, the Remote Desktop client should try a TCP connection as an alternative. However, due to the bug, the Remote Desktop client doesn’t do that and just keeps trying unsuccessful UDP connections.
How Do I Solve Remote Desktop Issues on Windows 11?
To solve the Remote Desktop problem on Windows 11, there are several solutions that you can try. Here are some of them:
Solution 1: Turn Off UDP Connection on Remote Desktop Client
The first solution you can try is to turn off UDP connections on the Remote Desktop client. This way, you’ll force the Remote Desktop client to use TCP-only connections, which will most likely work. To do this, you need to change the registry settings on the computer that you want to use to remotely access another computer. Here are the steps:
- Open “Run” by pressing (WIN + R) on your keyboard.
- Type “regedit” and press Enter to open the “Registry Editor”.
- Inside the “Registry Editor”, navigate to the following location:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client
- If you do not see the “Client” folder, right-click on the “Terminal Services” folder and select “New > Key”. Name the new folder “Client”.
- Right-click on the “Client” folder and select “New > DWORD (32-bit) Value”. Name the new value “fClientDisableUDP”.
- Double-click on the value “fClientDisableUDP” and change the data to “1”.
- Close the “Registry Editor” and restart your computer.
