Except this one had a count down timer at around 54 minutes left. There was also an option "I need more time...".

I X'd the box closed and went on thinking whatever.

54 minutes later, in the middle of typing an email, the system auto rebooted and "Configuring Update for Wndows 10" screen came up.

I took pictures of it with my cell which are kind of blurry because it's hard to have a steady hand during a good WTH rage.

Of course, they seem to be iterating on the update dialogs. I'm not saying it's to get past those avoiding the update, but it's probably to get past those avoiding the update.

When I arrived home, the computer was rebooted and upgraded to Windows 10...

The curious thing is that I have Bitlocker on all drives, including the system one, and it asks for the password on boot. Somehow they got over that (probably temporarily saved the key somewhere).

You should be flagged here then, not because you don't trust Reddit but because you haven't checked any other sources, including these linked in the comments here, long before you posted your comment!

It's documented by Microsoft:

https://support.microsoft.com/en-us/kb/3080351

"How to manage the Windows 10 upgrade

Automatic scenarios

The Windows 10 upgrade is automatically blocked (that is, no further action is required) on computers or other devices in the following scenarios: .."

Note: no further action is required to stop computer to being upgraded only on Enterprise!

"Non-automatic scenarios

You can manage the Windows 10 upgrade by using any of the following methods."

Managing here means -- you can read slowly the whole article -- the ability to disable automatic upgrade! No action taken -- upgrade happens. Even if you have hidden the previous update! You have to enter the proper new registry entry or group policy:

"administrators who want to prevent Windows 7, Windows 7 for Embedded Systems, Windows 8.1, and Windows Embedded 8.1 Pro clients from upgrading should enable the policy settings that are discussed in this article."

It's not that "no click" is needed, it's that the people who do that click don't have any idea what is going to happen, e.g. they are not the "qualified administrators" of their own computers. Like most of the people who let other people installing them software. Now it's just something like:

Dark pattern par excellence.

Hard to believe but true.

> I flagged this article on purpose because I don't consider a random Reddit thread to be a legitimate source.

Maybe you also won't consider a random HN thread to be a legitimate source, but if you ask MS employees you're sure to find some who were either hit by this or know someone who was hit by this.

Just to be clear are you or are you not claiming to be a Microsoft employee?

It's a mainstream journalist so mileage might vary quite highly, but probably a little more trustworthy than a Reddit thread. At first they talk about the Reddit thread but then say they caught it on their own box.

"I clicked 'update security' and it gave me Windows 10!"

But I've never seen an update security button that actually INSTALLS Windows 10, and that is specifically what this complaint is about, the upgrade starting on its own.

As I said if there is a bug that causes upgrades to occur without permission then people need to provide production steps. If there isn't a bug and Microsoft is doing it on purpose then why is it only impacting so few people? And how can we exclude user error?

I wonder how many people are going to disable future security updates thanks to the media coverage?

that's what I was getting at.

For example, if there was some UI which says.

"Get the Newest most Secure version of Windows (Download Now)"

with some fine print which says you will be installing windows 10 as part of the security upgrade

would that be considered 'user error' or user-hostile-design?
