Could somebody tell me: Is the latest Win10 1809 cumulative update, KB 4495667, forced or optional?
There’s a kind of unwritten rule that the first cumulative update each month gets pushed onto Win10 machines, and the second is an “optional” update — meaning you have to intentionally click on “Check for updates” (or download and install it) in order to get it going.
That’s considered acceptable behavior because the second updates are, traditionally, non-security updates. There’s no urgency in installing them. You only get bit if you’re a sucker, er, seeker and click Check for updates.
When the latest Win10 1809 cumulative update, KB 4495667, rolled out yesterday, it included the standard first-Tuesday admonition:
Install this update
This update will be downloaded and installed automatically from Windows Update.
I thought it was odd at the time, and fretted about warning people with an AskWoody Alert. Then shortly after the KB article appeared, @abbodi86 eased my fears and said it was for seekers only. I checked the KB article and it had been modified to say:
Install this update
To download and install this update, go to Settings > Update & Security > Windows Update and select Check for updates.
… which is the common “optional” non-security patch warning. That’s what the KB article says at the moment. Somebody slipped in a change to the KB article without mentioning it. Happens all the time. Since Google doesn’t cache KB articles, there was no way for me to verify the before-and-after contents.
But then Susan Bradley got hit.
@msftsecresponse https://t.co/8OvPkFV06U is this an out of band update otherwise why are you pushing it out to non seekers? The documentation says that it will only be installed if you check for updates. I didn't check, you pushed it. I'm in CA not impacted by Japanese era pic.twitter.com/dLIzQ7s6f9

The behavior Susan saw corresponds to the first version of the KB article, not the second version. Susan’s in California and doesn’t work with Japanese-era dating. Understand that this is the “second second” Win10 1809 cumulative update for April — it’s the latest patch for Win10 1809, not the stopgap issued on May 1, KB 4501835.
So which is it, Microsoft? Will the KB 4495667 patch get pushed onto Win10 1809 machines that aren’t actively blocking patches? Or did somebody screw up big time?
Again?
