Hi,
I have such problem on WSUS classifications I have enabled "Updates, Upgrades" and products I have "Windows 10, version 1903 and later, but all my windows 10 computers have max version 19041.1682 so it is windows 21h1, when I do on client computers check for any new updates it give me that computer is up to date, the same is on WSUS side it shows for that computer 100% installed:

Now when I do on this computer check updates from Microsoft online, then it immediately finding 21H2 update and start to install, then on wsus computer is visible with version 19044.1706.
Why my WSUS do not offer 21H2 upgrade?

    Do they have the latest SSU installed?
    https://www.catalog.update.microsoft.com/Search.aspx?q=KB4577266

    Try installing this manually on one of the systems, restart, and check for updates. Then see with the approvals process (https://www.ajtek.ca/wsus/how-to-setup-manage-and-maintain-wsus-part-6-selecting-your-test-systems-the-approvals-process/) if anything is marked as NEEDED now.

    And google led me astray.

    Microsoft combined SSU/LCU in December 2020 for Win 2004

    You should have the latest SSU if you have a recent (May) CU installed.

    Take one of the systems that is not picking up the feature upgrade
    Delete it from the WSUS console
    Run the client side script on it (https://www.ajtek.ca/wsus/client-machines-not-reporting-to-wsus-properly/)
    It should populate back into WSUS. Let it be for 1 hour and check back - has the system reported in?
    Now, go to the computer and see what updates it is claiming it needs.

    All my computers have installed all cummulative packages from may.
    This is the only solutions to run script on computers side? I have to many workstations to do IT manualny. I don't understand why all updates are installing every month but not this 21h2 upgrde. I don't even have a failed installation status for this upgrade IT means that there have not even been attempts to install this upgrade.
