What exactly does KB2952664 do?

Yep a person could be set on Automatic download and install updates

And as long as the magic Give me Recommended updates the same as Important updates box is Unchecked they would not be facing win-10 auto installing

Yea M$ has gone out of their way coming up with lame reasons why they have offered win-10 this way = no doubt :)

Using an excuse like M$ is receiving feedback that people can't find win-10 lol

Again you have to wonder whom M$ is receiving this feedback from = The blind :D

It's NOT just knowingly accepts it.

1. They HAVE put some sucker downloads in important updates.
2. They had a security update for IE that included some nagware.
3. I understand that they had a popup, if you unwittingly included one of their downloads, that offered to "upgrade" you, with ONLY an OK box.  NO "GET THE H OUT OF THERE" button.  So how many people would've known to either check the X in the corner, or kill it with task manager?
4. I used a work computer somewhere (not my regular work), and there was an icon in the system area that I thought was "display desktop".  It started to set up Win10!  Luckily I was able to cancel it!
5. I always used to accept ALL security updates and most others; occasionally checking if the name wasn't clear.  MOST of these sucker installs do NOT tell you that it is setting you up to install Win10; you can only google EVERY DAM ONE and see what you can find on it, generally not from microsoft.  So now I'm far behind in updates because I'm too busy to look up every one, and I can't even trust them with the security updates.  Tell me that is not underhanded at best.

This is NOT set up to trip up idiot users who don't deserve their job, it is microsoft making every effort to trap everyone.

I've said this before, I NEVER update operating systems -- I generally buy a new one in sufficient time to get the latest then.  I'm even way behind on that because I have no idea if I'll get one with Win10, or one upgraded to Win7 (knowing it will expire sooner).  A good part of that is that you can NOT refuse ANY update unless you forego all including security ones.  There's also my feeling that they will turn more and more standard features into extra cost subscriptions; I think they did that with some media player or something, I forget the details.  I likely already have other software that does it, but who knows what they'll take away next?  But mostly it's the inability to refuse updates, and with this current arrogance, they have proven to be untrustworthy in that.

I have disabled all I can, with the registry and group policies, that SHOULD stop me from accidentally be downgraded to Win10 or to get nagged about it.  I recently got GWX Control Panel, although I'm not sure if that stops anything or just lets you check if you fell for one of their updates.  So far it found nothing -- I just checked and found one thing I missed: I did not download anything but have not disabled their "Get Window 10' icon app.  I just clicked on that button to disable it.

Never before have I given this any thought, and likely not for this next computer, but I am already thinking of dumping Windows and going Linux next time.  It was NEVER an option before, and I have no idea if ALL my software would work there, but this arrogance has gone too far.

The most logical reason is the update settings are off that's all,

ThrashZone,

My Windows Update settings are identical to those shown in your post.

Many people have reported that the Windows 10 updates that coerce installation (or nag about installation) appear in their Important list .... while others report that these Windows 10 updates appear in their Optional list. In my case, I have seen these (previously hidden) Windows 10 updates sometimes appear in the Important list, and sometimes appear in the Optional list.

Microsoft has never documented what determines which list these previously hidden updates will appear, and I have not read any user-written post that explains the algorithm used to determine where these previously hidden updates will re-appear.

My point here is that these previously hidden updates can appear in one or the other list.

In whatever list they appear in (after Microsoft has unhidden them), sometimes these previously hidden updates appear checked ... sometimes unchecked. As you know, when they appear checked, then any user that has their Windows Update set to the default value of "Install Updates Automatically" will find Windows 10 being installed.

We can not assume that these (previously hidden) updates will only appear in the Optional list for every user, we cannot assume that these previously hidden updates will only be unchecked, we cannot assume that the end user is computer savvy and has the skills to understand Windows Update settings or Registry settings.

Lets not blame the (computer unsavvy) end user for ending up with Windows 10 on their computer. Microsoft is aware of the large number of computer unsavvy users and is taking advantage of them to meet their Windows 10 installation goals.

You are a cold man, Mr. Thrash.

I love it  :)

It's hard to sympathize with a business or individual that knowingly reserves win-10 or doesn't know how to oversee their business networks :)

But that is your bread and butter so it's all good but in law ignorance is not a defense and it is pretty clear if the person clicks on Accept instead of Decline on the win-10 terms to fully install win-10 it happens.

A couple of firings would help staff messing up systems and productivity in a heart beat ;)
