How to Fix Windows 11 RDP Black Screen After Windows Update

Posted on In 评论: Views:

After a Windows Update, RDP on Windows 11 might stop working correctly. Symptoms include a black screen upon connection, no visible mouse or interface, and an automatic disconnection after about a minute. This forces users to return to the local machine to investigate the issue.

Troubleshooting the Issue

Checking the RDP settings and firewall configurations revealed no issues. Given that black screen problems are common on Linux systems and often related to drivers, it was suspected that the NIC driver might be causing the issue.

Since the connection succeeded but disconnected after one minute, the wireless NIC was identified as a possible culprit.

Initially, the energy-saving option to "allow the computer to turn off this device to save power" in the wireless NIC settings was disabled, but the problem persisted.

In Device Manager, it was discovered that the NIC driver had recently been updated:

The NIC in question was Realtek 8811CU Wireless LAN 802.11ac USB NIC with a driver version of 1030.44.1014.2024.

Solution: Rolling Back the NIC Driver

The issue was resolved by rolling back the NIC driver to the previous version 1030.38.712.2019. After doing this, the Remote Desktop (mstsc) started functioning normally again, with no black screen.

Steps to Roll Back the NIC Driver

  1. Open Device Manager.

  2. Expand the Network adapters category.

  3. Right-click on the NIC (Realtek 8811CU Wireless LAN 802.11ac USB NIC) and select Properties.

  4. Go to the Driver tab.

  5. Click on Roll Back Driver and follow the on-screen instructions.

  6. Restart your computer to apply the changes.

  7. Test RDP to ensure the issue is resolved.

By following these steps, the RDP black screen issue caused by the NIC driver update can be effectively fixed.
