What exactly does KB2952664 do?

Didn't they sneak some W10 annoyware into an IE "security update" a few months ago?

I had to bite the bullet and take the SP2 rollup because I got a new PC.  I wasn't spending days with multiple reboots, each time checking to hide what should be hidden, to get up to date.  SO I installed GWX Control Panel and let it do the work for me (plus I googled and got from here things to do about telemetry) and did those things manually).

In about another month it should all be over.

I also found out that my processors may stop being supported in about a year and a half, that they will stop updates for the latest processors then.  I had thought they were going to not support them at all, so when Dell offered what I call the upgrade to Win7, I figured it hadn't kicked in with this processor yet.  I may be forced to do something at that time.

I don't understand why there hasn't been a class action suit yet.  We are forced to play games because they are FORCING an upgrade on people who absolutely don't want it, and claiming that they're doing it for our benefit.

I suspect Linux will not run many windows programs, plus my PC even needs specual drivers for USB3 (ALL ports) and my PCIe SSD hard drive, so chances are I'd have even more problems with that.  Until all this nonsense, I hadn't even given Linux a thought, and I work with it at work.

Unless you are a gluten for punishment, you will install GWX control panel, set Windows Update to NEVER, once a month manually start Windows update,  and hide all WINDOWS updates that are not labeled security.  If you will simply do this, you no longer have to worry about Win10.  It works for all of my clients.

KB2952664 just appeared in my Win 7 Windows Update for the 25th time..  Note that I have not hidden this patch.  I have no idea what changed.

Stage 1: Denial...

I am helping clients buy new PCs with Win7.  No problem really.  Just have to avoid 6th gen Intel processors.  I intend to stick with Win7 for along time to come.  I am not sure which is more insecure:  Win7 with not M$ security updates -- or -- Win10 with no privacy, lots of annoying adverts, and an OS that can morph itself into something I do not like. 

No self-respecting IT manager would ever recommend Win10.   Since about half of all Windows computers are business ones, M$ will have a very hard time selling it to them.  I believe M$ will eventually need to offer them something different.  I am holding out hope for that.  If you recall WinXP got an extension well beyond their original end date for this very reason.

My anti-Win10 analysis

Microsoft has turned a decades-long respected process — Windows Update — into a malware distribution system.  It is for all intents and purposes forcing innocent and content Windows 7 computer users into “upgrading” to its new Windows 10 version.  It promises to allow return to Windows 7 within 30 days.  That return process is flawed and leaves your computer virtually unusable and requires re-installation of Windows 7.  For some owners without a re-usable Microsoft product key or a factory restore partition on their computers, it results in a useless thing that used to be a computer.

Windows 10 is a completely new and very different Windows.  Nothing like anything you have used before.

1.   It is primarily an advertising/sales vehicle.  That’s the keen motivation and reason it is free.

2.   By adopting Windows 10, you sacrifice any privacy — essentially, anything on your computer is Microsoft’s and its partner’s to use as they see fit.

3.   Windows Update becomes non-optional.  You, as owner of your system no longer have control over what happens to your computer.  Microsoft will re-make Windows (on your computer) into what serves its purposes without asking your permission or opinion.

4.   Windows 10 as a system is still full of un-fulfilled promises and bugs.  Many of your programs will not run on Windows 10.  In fact, the “upgrade” process removes some.

So, if you like Windows 7, and most do very much so, I advise you to reject Windows 10 for the foreseeable future.  Be advised that Microsoft has committed to support Windows 7 until at least January, 2020.  Most of your current computers will last that long.

FYI, my last employer regarded me as a Usability expert.

I have has some experience with Win10, but very little.  Best I could tell, in my brief encounter was that 10 was 8 only worse.  My 150 clients know that I will not support 10.  If they choose to go that way, I will no longer support them.  Out of those 150, one has chosen to go that way.
