The BBC seems to think they've backpedalled (slightly) on this:
>> "Based on "customer feedback", Microsoft said it would add another notification that provided customers with "an additional opportunity for cancelling the upgrade" <<
Customer feedback? lol... yeah, I bet they got lots of that. And, I'm sure their word censor blanked out quite a bit of it too.
And this comment from another website:
>> Microsoft said users could still cancel the upgrade once the red X had been clicked. “With the free Windows 10 upgrade offer ending on July 29, we want to help people upgrade to the best version of Windows,” it said.
"Customers can choose to accept or decline the Windows 10 upgrade." <<
I'm almost certain if someone broke into 'MS Headquarters' all they would find these days is an army of robots (or aliens) programmed to conquer the world with Windows 10 - when they're not busy churning out useless, canned responses like the ones quoted above.
