Here are some common workarounds for issues that may be causing your computer to freeze with Windows 11:

Insufficient system resources: Close any unnecessary programs and background processes, and consider upgrading your RAM or CPU.
Conflicting software or driver issues: Uninstall any recently installed software or drivers that may be causing conflicts, and check for updates for your existing software and drivers.
Overheating or hardware failure: Clean the dust out of the fans and vents to improve airflow and prevent overheating, and check for any signs of hardware failure, such as strange noises or smells.
Outdated or corrupted operating system files: Run the Windows troubleshooter, check for and install any pending updates, and check for and repair any corrupted files using the built-in utility such as the “sfc /scannow” command in the command prompt.
Malware or virus infections: Run a full system scan with a reputable antivirus program, and remove any detected threats.
Power supply problems: Check that your power supply is functioning correctly, and ensure that your computer is plugged into a working outlet or surge protector.

If your computer continues to freeze or you are unable to resolve the issue using these workarounds, it may be helpful to contact the manufacturer or a professional for further assistance.

Terminate the Remote Desktop Using Windows Task Manager

To terminate a Remote Desktop session using the Windows Task Manager, follow these steps:

Press the “CTRL” + “ALT” + “DELETE” keys on your keyboard.
Click on “Task Manager” from the options that appear.
Click on the “Users” tab.
Locate the Remote Desktop session you want to terminate and select it.
Click on “End Task” button, it will end the remote desktop session.

Alternatively, you can also use the command line to end a Remote Desktop session. Open the command prompt and type “query session” to view a list of active sessions. Then type “logoff sessionid” (where sessionid is the ID of the session you want to end) to end the specific session.

It is worth noting that if you have a Remote Desktop session running in full screen mode, you may have to press the “CTRL” + “ALT” + “PAUSE” keys to access the task manager.

If you are trying to close a Remote Desktop session on a remote computer, you will need to have administrator access to that computer in order to end the session.

Enable the Turn Off UDP On Client Policy

To enable the “Turn off UDP on client” policy on a Windows computer, you will need to use the Group Policy Editor. Here are the steps to do this:

Press the “Windows” key + “R” to open the Run dialog.
Type “gpedit.msc” and press Enter. This will open the Group Policy Editor.
Navigate to “Computer Configuration” > “Administrative Templates” > “Windows Components” > “Remote Desktop Services” > “Remote Desktop Session Host” > “Connections”
Double click on the “Configure transport settings” policy to open it.
Select “Enabled” and check the “Use only TCP” option.
Click “Apply” and then “OK” to save the changes.

This will disable the use of UDP for Remote Desktop connections on the client computer. By default, Remote Desktop uses both TCP and UDP protocols to transfer data. UDP provides a faster and more efficient way to transfer data but it is less reliable than TCP, turning off UDP will make the connection more reliable but it could cause some lag.

After making this change, you may need to reboot your computer for the changes to take effect.

It is worth noting that this setting only applies to Remote Desktop connections to the client computer, it will not affect other network connections on the computer.

Restart Device Manager for Frozen OS
