You think that's bad? I only upgraded to Windows 10 last week, and within minutes of booting it up, it quietly started downloading "Candy Crush Soda Saga" without my permission. I only caught it because I noticed the download indicator in my Start menu, at which point I cancelled it. Apparently there's no simple user option to turn these auto-downloaded apps off either.
The thing that grinds my gears is that MS cleary does not think people use Windows to do real work any more. None of this shit flies in an environment where you are billing hourly and need to be in control of your own software/hardware.
