This past week has seen a bizarre turn of events for those who are using the most recent version of Windows 10, the Anniversary Update, version 1607.

On Friday, Dec. 9, Microsoft released a cumulative update for version 1607. As I described last Friday, cumulative update KB 3201845 brings Windows 10 version 1607 up to build 14393.479. I installed it through Windows Update on two Win10 1607 machines (see screenshot).


But for reasons unknown, Microsoft didn't update its official Windows 10 update history page to mention the new version. KB 3201845 was, and is, available for download from the Microsoft Update Catalog. But the associated KB article was pulled down last night. Going to the KB location brings up a "This page doesn't exist" notification.

When KB 3201845 was first released, many of us wondered why Microsoft would push out a cumulative update just a few days before Patch Tuesday (or the "B Week Tuesday" in Microsoft-speak). It doesn't make any sense, even though KB 3201845 has been around in the Windows Insider Preview Release ring since Nov. 30.

Now, it appears references to the patch have simply been swept away.

KB 3201845 has a bad rap. Many "news" sites report that it causes the "Wi-Fi doesn't have a valid IP configuration" internet disconnect bug when, in fact, the patch has nothing to do with the bug. I see reports even today that the patch caused IP addresses to be reassigned to 196.x.x.x, but that isn't the case.

What happened to KB 3201845? I doubt that we'll ever know. But tomorrow expect a Patch Tuesday cumulative update for version 1607 that will obviate the need for KB 3201845.

Let's see how history is re-written.

As for the internet disconnect bug -- I still don't have any idea what caused it, or why Win10 1607 machines suddenly started spontaneously disconnecting on Dec. 7. Microsoft has posted a banner on every page saying "If you are experiencing issues connecting to the internet we recommend you restart your PC," but there's been no mention of why or how the problem started, and when or if it will be fixed.
