    The registry entries, shown in the post.
    I see. So the updated ucode in BIOS causes an update to the registry which tells it that KB100347 is unnecessary. So some people don't even get that update.
    The BIOS/UEFI update doesn't change anything in the registry.
    Without being a Microsoft engineer, I think that in clients, regardless of the existence of the registry entries, you will be updated if your current μcode is older than the one included in the Microsoft update. But again to be on the safe side, just add the two registry entries.
    I didn't have them, since I never used the Microsoft μcode, as hp is very fast in BIOS updates, but I did add them. They don't harm anything.

    Point is you should have them, otherwise the fixes are not automatic nor controllable. The OS updates should set the registry entries, hence why tools like InSpectre could 'disable' the mitigations.

    Exactly as you said, "The OS updates should set the registry entries".
    If someone (me for instance) has never run the Microsoft updates, he doesn't have them and should add them.

    I'll just go ahead and download it back on from the Windows Update Catalog if you all think that is a good idea. It says "last updated 5/18" which is confusing but this is the right one.

    These uCode updates are not OS patches. They should only contain the uCode (newer version of the .dll) they do not contain registry settings.

    Plus the patches are only effective if the OS code is updated. You can change the registry settings all you like but you can't activate a patch if it isn't present.

    e.g. If you do not have 17134.228 or higher you can't enable against L1TF.

    The Powershell script will tell you if the uCode is sufficient (Hardware), it will also tell you if the registry switch and the cumulative update is active (OS).

    So I'm at 17134.254 does that mean I don't need KB100347 since I'm already at a higher level?

    it will also tell you if the registry switch and the cumulative update is active (OS)
    The Powershell script (I assume you are talking about the second one ddelo posted; I won't understand that output.

    To understand the output, of the Microsoft script, read this document

    Thanks. I went ahead and reinstalled KB100347 since winactive recommended it be on there anyway and said it doesn't interfere with present updates unless it is newer. Hopefully registry entries are set properly. I don't understand the registry switch being active and hopefully this did not mess up anything since I installed KB4346783 earlier and that is a more recent update than this. Should I uninstall/reinstall KB4346783 to put them back in chronological order?

    Side Question: Do cumulative updates build off each other? If I were to not install one but then install the one after would that include all the fixes from the previous update or would I not be able to install it because the previous was never installed?

    Why don't you check them and tell us if they are installed and with what values?

    Yes you should.

    That's what cumulative means. They include all previous ones.
    If there are prerequisites by an update, it's stated clearly which one it is.

    You've just hit the definition of Cumulative Update on the head almost.

    The latest update contains all the fixes since 17134.1 (base version 1803) to date. You don't need interim OS patches.

    Run the PowerShell script as @ddelo says; that tells you if everything is OK

    Edit: looks like we cross-posted
