I think this slightly understates just how sleazy Microsoft were about it, if anything. Before the dialog that interpreted closing it with the X in the corner as agreement to install Windows 10, they rolled out a similar-looking dialog where that was the only way to avoid install Windows 10 - clicking on any of the buttons in the dialog would cause it to be installed.
Over the past year I've noticed a lot of things mysteriously getting installed, things moving around, etc. I don't mind automatic updates so long as there's a separation from the new features and bug fixes. There should be a base core of apps that are necessary and a set of opt-in add-on features. It's time to move to Linux on laptop/desktop/tablet I think. While I love my surface pro 3 and the Windows 10 experience…
Microsoft actually offers this. Enterprise customers requires it.
