Windows Server 2022 RDP Connection Issue After KB5122882

Some Windows Server 2022 VPSs may experience Remote Desktop connection problems after installing Microsoft update KB5122882, which updates Windows Server 2022 to build 20348.5622.

You may see errors such as:

The two computers couldn't connect in the amount of time allotted.

In some cases, RDP may also report that the password is incorrect even though the same password works through VNC or console access.

Restarting the VPS may make RDP work again temporarily, but the issue can return.

Based on our testing, rolling Windows Server 2022 back from build 20348.5622 to the previous build 20348.5499 resolves the issue on affected systems.

How to Fix the RDP Issue

Access your VPS.
If RDP is still working, you can connect normally.
If RDP is not working, use the VNC or console option from your client area.
Download the NovaRDP fix tool:

Download Windows Server 2022 RDP Fix Tool
Copy the downloaded Fix-RDP-Server2022-KB5122882-v2.bat file inside your Windows VPS.
Double-click the file.
Windows may ask for Administrator permission. Click Yes.
The tool will automatically check whether KB5122882 / build 20348.5622 is installed.

If the update is not installed, the tool will make no changes.

If the update is installed, the tool will begin removing it.
Wait for the process to finish.

Do not close the window while the update is being removed. The process may take several minutes depending on the VPS.
Once you see:
```
Rollback command completed successfully.
```
the update has been removed successfully.
You will then see:
```
Press ENTER to reboot now.
```
Press Enter to reboot the VPS.
During reboot, Windows may display messages such as:
```
Working on updates
```
or:
```
Getting Windows ready
```
This is normal while Windows completes the rollback. Do not force power off the VPS during this process.
Once Windows starts again, try connecting through RDP.

Expected Windows Version After Rollback

After the rollback, Windows Server 2022 should return to build:

20348.5499

Will This Delete My Data?

No. The tool does not reinstall Windows, format your VPS, or delete your files.

It only removes the affected Windows cumulative update and temporarily prevents it from reinstalling automatically.

Important

This fix is intended for affected Windows Server 2022 systems running KB5122882 / build 20348.5622.

If the affected update is not installed, the tool will detect this automatically and make no changes.
