nathan:CYaBro:nathan:freitasm: And yet @nathan keeps saying there is no way for Windows 10 to be installed without user knowing and approving it...
They reserved their free Windows 10 upgrade. Now it's installing.
And again you are missing the point.
Yes they may have reserved the upgrade BUT they got no warning of that upgrade installing, it just did it when it felt like it.
I have seen so many variations on the Windows 10 upgrade prompts I think even Microsoft don't know what users are seeing now, and what prompts they are getting for the installation, if any.
It notifies you that your reservation is coming due and if this schedule is a good time to upgrade
The it notifies again 30 mins before that time
Then you still need to agree to the End User Licensing Agreement
Then you still have 31 days to roll back the update to your previous OS
But that's not true and I've seen it myself.
Got none of those notifications, nek minit Windows 10 installing.
So the only option was to roll back.
