The September 2022 preview release is listed in Windows Server Update Services
IT administrators who utilize Windows Server Update Services (WSUS) might notice that the Windows September 2022 preview update, known as the ‘C’ release, is listed among the updates available from WSUS. This listing is an error. Preview updates are generally available for manual importing via the Microsoft Update Catalog and Windows Updates.
This issue might also affect the installation of the September 2022 Cumulative Update Preview for .NET Framework, which is also generally available via Windows Update and Microsoft Update Catalog…
Workaround: The Windows September 2022 preview release was made available via Microsoft Update Catalog. We recommend IT administrators to use this release channel moving forward.
Please note: In environments where WSUS is configured to auto-approve updates and also auto-decline superseded content, the Windows September 2022 Security update may subsequently be auto-declined and auto-expired from the client view..
