Security News > 2023 > February > Microsoft: Some WSUS servers might not offer Windows 11 22H2 updates
Microsoft says that some WSUS servers upgraded to Windows Server 2022 might fail to push Windows 11, version 22H2 updates released during this month's Patch Tuesday to endpoints across enterprise environments.
This known issue only affects WSUS servers upgraded from Windows Server 2016 or Windows Server 2019.
"The updates will download to the WSUS server but might not propagate further to client devices. Affected WSUS servers are only those running Windows Server 2022 which have been upgraded from Windows Server 2016 or Windows Server 2019," Microsoft said.
"This issue is caused by the accidental removal of required Unified Update Platform MIME types during the upgrade to Windows Server 2022 from a previous version of Windows Server," the company added.
"This issue might affect security updates or feature updates for Windows 11, version 22H2.".
Until a fix is available, Microsoft provides admins with impacted WSUS servers a temporary fix requiring them to re-add the inadvertently removed UUP MIME types.
