  • Mysterious Windows 8.1 patch KB 4039871 making the rounds

    Posted on August 26, 2017 at 07:03 CDT by • Comment in the Forums

    I have no idea what it is, but there are reports of a new patch delivered on Friday night, called

    2017-08 Preview of Monthly Quality Rollup for Windows 8.1 for x64-based Systems (KB4039871)

    Reportedly, it is marked important but optional. There is no KB article as yet, no entry in the list of Windows 8.1 updates, and nothing in the Microsoft Update Catalog.

    Günter Born reports that one of his readers said four of his eight Windows 8.1 systems were updated overnight. His guess is that this undocumented update fixes a bug in the Rollup Preview for September, KB 4034663, which is also officially called the ” 2017-08 Preview of Monthly Quality Rollup for Windows 8.1 for x64-based Systems (KB4034663) .”

    There’s a confirming report from Japanese language site Winveg. That may be significant because the original 2017-08 Rollup Preview, KB 4034663, has a known bug “Japanese IME may hang in certain scenarios.”

    Of course, I recommend that you avoid it like the plague – let the other beta testers iron out problems with Microsoft’s patches, especially Previews like this one.
