Microsoft launched an emergency out-of-band update to the Windows Server series of server systems recently. This out-of-band update mainly addresses performance rather than potential security issues.
According to Microsoft’s official blog, this out-of-band update fixes remote desktop performance problems, including but not limited to a black screen or severe freezes after connecting.
Affected operating systems include Windows Server 2012 R2, 2016, 2019, 2022, 2012, and earlier versions will no longer be supported and will no longer be updated.
The updates released this time only support Windows Server 2012 R2 and Windows Server 2019, and other version updates will be released one after another.
“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.”
At present, Windows Server 2012 R2 and Windows Server 2019 have received out-of-band updates, and other versions need to wait temporarily.
Special attention is that the above out-of-band updates are optional update types and will not appear in the system check update, so download and installation will not be performed automatically.
The company that wants to install must manually download the out-of-band update package and then manually install it. After installation, please restart the system as prompted to make the update take effect and then test the remote desktop performance.
