Emergency Windows Server update fixes Remote Desktop issues

Microsoft has released an emergency out-of-band update to address a Windows Server bug leading to Remote Desktop connection and performance issues.

Microsoft is releasing Out-of-band (OOB) updates today, January 4, 2022, to resolve issues in which Windows Server might experience a black screen, slow sign in, or general slowness, the company explains.

You might also be unable to use Remote Desktop to reach the server. In some circumstances, the server might stop responding.

Affected platforms include Windows Server 2022, Windows Server 2019, Windows Server 2016, and Windows Server 2012 R2.

The updates that address this issue are not available from Windows Update and will not install automatically on affected systems.

You can get the standalone KB5010196 update package for Windows Server 2019 using the instructions available in this knowledgebase article.

You can also download the update from the Microsoft Update Catalog. Enterprise admins can import this update into Windows Server Update Services (WSUS) manually using the instructions available in the Microsoft Update Catalog.

KB5010196 is a cumulative update, so you will not have to deploy previous Windows Server updates before installing it.
