If you’ve been wondering about your Win10 version 1803 or 1709 patches, you aren’t alone. Looks like we have a completely new Windows patching rabbit hole.

Let's start with the latest version of Windows. In the past 15 days, we’ve had four cumulative updates for Win10 version 1803:

  • KB 4457128 — The Sept. 11 Patch Tuesday cumulative update included a host of security fixes that brought 1803 up to build 17134.285.
  • KB 4464218 — The Monday, Sept. 17, cumulative update fixed a bug in all of Microsoft’s Win10 1803 patches since late July, which blew away Microsoft Intune. Build 17134.286. I have no idea why Microsoft released the fix on a Monday instead of a Tuesday.
  • KB 4458469 — The Thursday, Sept. 20, dump of dozens of bug fixes brought the build number up to 17134.219. For reasons as yet unexplained, Microsoft stopped pushing KB 4458469 late on Sept. 20 or early Sept. 21, although it remained available for manual download. We never did figure out if the patches were doled out to “seekers” — those who had the temerity to click “Check for updates” — or if they somehow made it into the ecosystem through less nefarious means.
  • A different (but identically numbered) KB 4458469 was released yesterday, Sept. 26. Let’s call it KB 4458469 v2. It brings 1803 up to build 17134.320.

What is this new KB 4458469?

Apparently, KB 4458469 v2 is a Wednesday fix for a botched Thursday kitchen-sink cumulative update, which followed a Monday cumulative update that specifically fixed a bug introduced in the Patch Tuesday patch. Got that?
