Stopping the b*gger dead
Who will rid me of this turbulent upgrade?
After I found a couple of my PC's had mysteriously downloaded 6 Gigs of Win 10 rubbish this despite having updates set to "Download and let me decide when to install" - So I did a bit of digging , This is what I found.
"Windows 10 Automatically Downloading On Windows 7 And Windows 8", as is reported here
this was despite disabling GWX , hiding the updates and doing other suggested Registry Hacks
It seems that a KB Update (KB3012973 - Upgrade to Windows 10 Pro) is the culprit, I can't find any info on M$ Site regarding it, but it was there.
I also noticed that there were two entries in "View Installed updates" that said :-
Upgrade to Windows 10 (No KB Number) - Failed - (Recommended)
M$ are crafty bastards !!! - But dig deeper and there is an M$ solution, although I'm not sure I trust them further than I can throw them
It is entitled - How to manage Windows 10 notification and upgrade options -
So what can you do to stop the upgrade ?
First :- What you need is
for Win 7 - KB3065987 installed (may already be installed but best to check) - Note This article describes an update that contains some improvements to Windows Update Client in Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1. This update is incompatible with Windows Server Update Services (WSUS) servers without the hardening update 2938066.
and for Win 8.1 - KB3065988 (may already be installed but best to check) Note - This article describes an update that contains some improvements to Windows Update Client in Windows 8.1, Windows RT 8.1, or Windows Server 2012 R2. This update has a prerequisite.
Open up your registry editor using the Start Menu search or by pressing WIN + R and typing regedit and hitting enter, and then navigate down to the following key:
You will probably have to create the "WindowsUpdate" key on the left-hand side, which you can do by right-clicking the Windows node.
Click on that new key, and then create a new 32-bit DWORD called DisableOSUpgrade on the right-hand side, and give it a value of 1.
So only time will tell if this has killed the beast for good !!
About time M$ came clean and issued that as a formal statement rather than the BS line of :-
"we help customers prepare their devices for Windows 10 by downloading the files necessary for future installation. This results in a better upgrade experience and ensures the customer’s device has the latest software.”
