Don't bang the door on your way out.
At home I've had to constantly fight with a media pc, laptop and desktop machine to stop this from installing or downloading. The media pc is going to Linux once I get round to plugging in a spare hard drive and setting it up (just to make sure I can get everything to work), the laptop and desktop are already dual boot and once Microsoft bork Windows 7 enough they will switch completely. Happily my server runs Debian and a little treasure it is, it updates when I tell it with no problems and does everything I throw at it (which is a lot)
As far as upgrades and offers go this has to be the worst decision Microsoft have ever taken, installing telemetry, forcing updates and then moving to the soon to be subscription model.
