• Once again, KB 4023057 gets pushed out to all Win10 versions — and you don’t want it

    I just switched off the metered connection on my production machine, and what to my wondering eyes should appear…

    KB 4023057 “Update to Windows 10, versions 1507, 1511, 1607, 1703, and 1709 for update reliability” isn’t available in the Microsoft Update Catalog.  Per the KB article

    Only certain builds of Windows 10, versions 1507, 1511, 1607, 1703, and 1709 require this update. Devices that are running those builds automatically get the update downloaded and installed through Windows Update.

    This update is also offered directly to Windows Update Client for some devices that have not installed the most recent updates. This update is not offered through the Microsoft Update Catalog.

    We’ve seen a patch with the same KB number numerous times in the history of Win10. @ch100 explained it thusly:

    KB4023057 was and still is one of the most weird and unexplained updates in the recent times. This update has never been offered to WSUS, but only to Windows Update. This would indicate that it meant for unmanaged end-users and unmanaged small business users…

    This patch may be harmless, but why it was released and where it actually applies, it is still a mystery.

    The KB article was updated on Sept 6.

    My recommendation: Fuhgeddaboutit. When you’re good and ready to upgrade to 1803 (or 1809, or — in my case — 1709), let Windows figure out what it needs to pull you into the borg.

    UPDATE: Günter Born has a detailed description.
