2021-05 Cumulative Update for Windows Server 2019 for x64-based Systems (KB5003171): Not Applicable
2021-05 Cumulative Update for Windows Server 2019 for x64-based Systems (KB5003171) is downloaded in WSUS and approved for installation. It is showing not applicable. I have tons of Windows Server 2019 servers.

Prerequisite:
You must install the May 11, 2021 servicing stack update (SSU) (https://support.microsoft.com/en-us/topic/kb5003243-servicing-stack-update-for-windows-10-version-1809-may-11-2021-0941fe82-b9f4-40fb-845d-63e70c1f9242) or later before installing the latest cumulative update (LCU). SSUs improve the reliability of the update process to mitigate potential issues while installing the LCU and applying Microsoft security fixes. For general information about SSUs, see https://docs.microsoft.com/en-us/windows/deployment/update/servicing-stack-updates and https://support.microsoft.com/en-us/topic/servicing-stack-updates-ssu-frequently-asked-questions-06b62771-1cb0-368c-09cf-87c4efc4f2fe.
Interesting. I'm seeing the same issue where my 2019 servers are showing this update as "Not Applicable" when checking against my Wsus. However if I check against MS update servers, it does label the update as needed, and doesn't flag the servicing stack update you mentioned.
Also, if this is true about the order, that adds a lot of complexity into people's GPO settings for updates as GPOs only allow us one 1 designated time to install updates, not two. I would have expected that before the roll ups when there were a ton of updates per month.
I'll update if I can find out anything else.
Looks like if I approve both the servicing stack update and the cumulative update, they both get installed by clients when checking for updates, even if the cumulative doesn't show as needed in the Wsus console. So just approve both as normal!
