Remote Desktop intermittently freezes

“Hello everyone. I used Windows 10 machine to remote access at work for a long time. However, I found the Microsoft Remote Desktop freezing from time to time after the update. There’s no RDP error appearing on my PC, and the issue remains still even though I shut down and reboot the PC. What can I do now?”

3 solutions for Remote Desktop freezing

It is said that the issue is because the RDP protocol has lost some of its resilience to packets getting lost or out-of-order. Moreover, this may be triggered by the bug in Windows 10 that is unable to switch between TCP and UDP protocol seamlessly. Therefore, what we should do is prevent UDP and switch to TCP. Here we introduce 3 solutions to tell you how to fix Remote Desktop freezing on Windows 11, 10, 8... which are unfreezing RDP by running CMD, using Registry Editor, and Group Policy to disable UDP.

Solution 1. Unfreeze RDP by running CMD

Step 1. Search “CMD” in the search box and then right-click the option and choose “Run as Administrator”.
