I have just read your #2353190 post about KB5001205, the latest 1909 SSU, which was released March 25. My latest 1909 SSU, KB4601395 (2021-02), is supposed to be superseded by this mentioned latest SSU, according to the MS Catalog.
I have checked the bulletin on SSU KB50001205 and it says the update is available through Windows Update and will be downloaded and installed automatically.
Shouldn’t I be seeing it by now? I have GP=2 notify download/install, but NO download button for it has appeared. The asterisked remark about managed settings says “We’ll ask you to download updates, except when updates are required to keep Windows running smoothly. In that case, we’ll automatically (my bold-face) download those updates.” I have checked “Installed Updates” and it’s not been installed automatically (on its own, behind the scenes).
I should add that SSU KB5001205 is supposed to address the problems with installing KB4535680 (2021-01), which was supposed to address the Secure Boot Security Feature Bypass Vulnerability (CVE-2020-0689) and which I hid in January.
Given these aspects of 1909’s latest SSU KB5001205, should I be downloading and installing it instead of SSU KB50000908 — thereby a) fixing the Secure Boot problems with KB4535680; and b) satisfying the need for the correct SSU for KB5001648 to fix the printer problems?
