You should update your Windows OS, the Device Drivers and the RPD software.

It may sound unrelated, but sometimes, graphics card drivers tend to create a conflict with the CredentialUIBroker.exe file and trigger the Remote Desktop error on Windows. Therefore, it’s suggested that you definitely update the graphics drivers to the latest version to get rid of the error.

3] Replace the EXE file with a fresh copy

If the SFC and the DISM scan fail to fix the error, which is unlikely in our opinion, you may consider replacing the CredentialUIBroker.exe with a fresh copy. For this, you can copy the file from another healthy system, paste it into the System32 folder, and replace the old file.

You can also download the EXE file from a trusted source.

4] Remove saved credentials

If the error states that the RDP server doesn’t allow saved credentials as the server isn’t completely verified, it could indicate a bad/expired certificate. In this case, remove your saved credentials and the error should be fixed.

5] Additional troubleshooting methods

Run a virus scan on your PC using the built-in Windows Security or use third-party antivirus software from a reputable company.
disable the firewall temporarily to check if that’s blocking the process.
Perform a clean boot to remove any third-party application interferences and see if that helps.
Check if your PC’s BIOS needs an update.

How do I fix the Remote Desktop error?

To fix the remote desktop error, the first thing you should check is if the operating system (OS) configuration is correct. If the OS is fine, you can then check if the network connection is working fine, or if the firewall is blocking the application. Also, check if the remote desktop settings are correct. At the same time, make sure that access to the remote desktop is enabled and that you are using valid user credentials.

Why won’t my credentials work in RDP?

If your credentials are not working on the remote desktop (RDP), it could be possible that the network profile is set to public. This means that your computer is protected at public hotspots and it will block any incoming connections.
