    Mysterious win update KB4033637


    My Windows 10 Pro (release 1607) automatically installed a patch today (KB4033637). There is no KB article for this patch and if you google it, you wouldn't find anything. What the hell is going on with Microsoft?..this is a kind of a bug or something because my winver shows build 14393.1593 still the same from August 8th. *Start *BSOD *Busted

    Windows 10 Update KB4033637

    The best explanation I can offer today, it has something to do with upgrade to W10 V1703 and privacy settings confirmation - but it's a guess, based on my observations (kind of obscurity theory ;-) so far). See the following post:

    KB4033637 fails to update

    AFAIK the update is not available for offline installation. It's not in Microsoft Update Cataloge

    The best explanation I can offer today, what this update do, is contained within the following post: Windows 10 V1607: Mysterious
    Update KB4033637


    If the update installation fails, something in Windows 10 is broken (perhaps third party antivirus tools are blocking).

    This is the second time I've posted this week about poor software QA from MS. The update installed on two of my PCs and referenced this link https://support.microsoft.com/en-us/help/4033637

    Don't MS software engineers take the elementary step of installing their updates then following through Windows Update to see what is reported?

    You can find downloads for KB4033637's .cab file on a few third-party sites (and even a few sites with links to get them direct from Microsoft's servers) but no official Microsoft link is available, even on the Update Catalog.

    The clues that it was for the compatibility appraiser were in the names of the .dlls and .exe it contains, particularly the appraiser.dll and compattelrunner.exe. Now confirmed by the long overdue KB article:
    A 'feature update' is what Microsoft call a new release of Windows, meaning the Creators Update and (soon) the Fall Creators Update.
     
  12. roy111 Win User
    So it is an update for another update, right?

    Mysterious win update KB4033637

    It's an update to 1607's compatibility appraiser, that's part of the mechanism that determines if and when you see the Creators Update appear in your Windows Update.

    Creators is really an upgrade to version 1703, you won't see it in windows update if there are compatibility issues with your specific hardware or software. If your system isn't compatible yet it won't be delivered to you until (like the Broadcom issue) a fix has been put in place. It may also be assessing your compatibility for the upcoming 1709 Fall Creators Update.

    EDIT: coming 17th October...
    Windows 10 Fall Creators Update coming October 17th 2017
