Microsoft says some WSUS servers upgraded to Windows Server 2022 may fail to push Windows 11, version 22H2 updates released on this month’s Patch Tuesday to endpoints in enterprise environments .

This known issue only affects WSUS servers upgraded from Windows Server 2016 or Windows Server 2019.

Microsoft Configuration Manager (part of Microsoft Endpoint Manager) is not affected by this issue.

“Updates will be downloaded to the WSUS server but may not propagate further to client devices. Affected WSUS servers are only those running Windows Server 2022 that have been upgraded from Windows Server 2016 or Windows Server 2019” , Microsoft said.

As Redmond further explains, these issues result from the accidental deletion of .msu and .wim MIME types during the upgrade process to Windows Server 2022.

“This issue is caused by the accidental removal of the required Unified Update Platform (UUP) MIME types when upgrading to Windows Server 2022 from a previous version of Windows Server,” added the society.

“This issue may affect security updates or feature updates for Windows 11, version 22H2.”

Microsoft is working on a fix for this known issue and will provide more information with a future update.

How to Fix Affected WSUS Servers

Until a fix is ​​available, Microsoft is providing administrators of affected WSUS servers with an interim fix requiring them to re-add inadvertently deleted UUP MIME types.

The procedure for manually adding these Unified Update Platform file types requires administrators to follow these steps:

  • On your Windows Server installation, open Server Manager.
  • Select Internet Information Services (IIS) in the left column.
  • Right click on your server in the server list.
  • Select Internet Information Services (IIS) Manager.
  • Select your server from the list of connections on the left side of the window that opens.
  • In the center pane, scroll down and double-click MIME-type.
  • On the right, select Add.
  • Create a MIME type with extension “.wim” and MIME type “application/x-ms-wim”.
  • Select Add Again.
  • Create a MIME type with the “.msu” extension and the “application/octet-stream” MIME type. See the following picture.
Add the MIME type .wim
Adding the .wim MIME type using the Internet Services Manager (Microsoft)

Administrators can also add missing file extensions using the following PowerShell commands (each line can be selected by double-clicking):

& $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"]"
