Windows 11 KB5053598 Update: RDP Disconnections and BSOD Issues

KB5053598, released March 11, 2025, aimed to address security vulnerabilities and introduce new features. However, it has introduced significant problems, including disrupted remote desktop connections and system crashes. These issues can severely impact productivity and data access. Here's how to address them:

Resolving KB5053598 RDP Disconnection Problems

Solution 1: Disable UDP on the Client

This workaround forces Remote Desktop clients to use TCP instead of UDP.

1. Open the Local Group Policy Editor (search for "Edit group policy").
2. Navigate to: Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client.
3. Double-click "Turn Off UDP On Client," select "Enabled," and click "Apply" and "OK."

Solution 2: Specify RDP for the Security Layer

While intended for enhanced security, selecting RDP as the security layer has proven helpful in stabilizing RDP connections.

1. Open the Local Group Policy Editor.
2. Go to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Security.
3. Double-click "Require use of specific security layer for remote (RDP) connections," enable it, and choose "RDP" for "Security Layer."

4. Click "Apply" and "OK."

Solution 3: Modify the Registry (fClientDisableUDP)

Creating or modifying a registry value can resolve the issue.

1. Open Registry Editor.
2. Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client.
3. If fClientDisableUDP doesn't exist, create a new DWORD (32-bit) Value and name it fClientDisableUDP.
4. Set its value data to 1 and click "OK." Restart your computer.

Solution 4: Uninstall KB5053598

As a last resort, uninstall the update and temporarily pause Windows updates. Go to Settings > Windows Update > Update history > Uninstall updates. Select KB5053598 and uninstall it. You can also pause updates within the Windows Update settings.

Addressing KB5053598 BSOD Errors

Solution 1: Safe Mode

If you encounter a BSOD, boot into Safe Mode to access your files and uninstall the update. To enter Safe Mode, repeatedly restart your computer until the "Automatic Repair" screen appears. Choose "Advanced options" > "Troubleshoot" > "Advanced options" > "Startup Settings" > "Restart," then press F5.

Solution 2: Clean Install

If Safe Mode is inaccessible, a clean Windows installation might be necessary. Before doing this, back up your data using a tool like MiniTool ShadowMaker or MiniTool Power Data Recovery (bootable edition required for unbootable systems). Create Windows installation media on a working computer, connect it to the affected PC, and follow the on-screen instructions to perform a clean installation.

Conclusion

These solutions aim to resolve RDP disconnection and BSOD issues caused by KB5053598. Remember to back up your data before attempting major troubleshooting steps like a clean install.
