Re: The KB article has a "feedback" section
Here's the feedback I left :
"X means NO ! See https://msdn.microsoft.com/en-us/library/windows/desktop/dn742499%28v=vs.85%29.aspx . You just made us give our 11-year-old daughter a *severe* telling-off for approving this unwanted upgrade, while she denied everything. We told her that we weren't angry that she had made a mistake, just angry that she wouldn't take responsibility, while she tearfully insisted that she had simply closed the box by clicking on the 'X' as we'd taught her. Hope you're proud of yourselves. I'm off to buy a copy of 'Linux for Dummies', I'm sick of your BS."
