Microsoft has released updates to fix a bug that was previously impacting the Windows Server Update Services (also known as WSUS). The company detailed on the Windows Health Dashboard that the issue prevented the distribution of updates to client devices running Windows 11 version 22H2 as well as Windows Server 2022.

Windows Server Update Services is a service that lets IT admins manage the deployment of updates and patches for products (such as Microsoft Office, Exchange Server, and SQL Server). The service downloads updates from Microsoft’s servers and distributes them to client devices on the corporate network. It helps organizations to reduce bandwidth usage and improve network security and stability.

“Updates released February 14, 2023 or later might not be offered from some Windows Server Update Services (WSUS) servers to Windows 11, version 22H2. The updates will download to the WSUS server but might not propagate further to client devices,” Microsoft explained. “This issue is caused by the accidental removal of required Unified Update Platform (UUP) MIME types during the upgrade to Windows Server 2022 from a previous version of Windows Server.”

According to Microsoft, the issue only impacts WSUS servers running Windows Server 2022 that have been upgraded from Windows Server 2019/Windows Server 2016. However, the company confirmed that the bug doesn’t affect Microsoft Configuration Manager.

Microsoft has also provided a temporary fix for customers who haven’t installed the July 2023 Patch Tuesday updates on their machines. The company recommends IT admins to re-add the missing UUP MIME types via PowerShell commands.

  • & $Env:WinDir\system32\inetsrv\appcmd.exe set config /section:staticContent /+”[fileExtension=’.msu’,mimeType=’application/octet-stream’]”
  • & $Env:WinDir\system32\inetsrv\appcmd.exe set config /section:staticContent /+”[fileExtension=’.wim’,mimeType=’application/x-ms-wim’]”
