Disabled update service before "Creator's Update"
Knowing that MS decided their product could do no wrong I disabled the update service after I installed 10. I'd enable it monthly to update before switching it off again. I managed to avoid the massive cock-up that was the endless boot loop doing this and felt it justified my choice. When I heard about the junk being pushed and privacy being torn out in the Anniversary Update I disabled it before it was pushed out.
As of today I still haven't enabled it again and while I worry about bugs and unpatched exploits I feel less worried about those than MS and their updates. Congratulations MS! You've made it so even people with legitimate versions of your software don't want to update it.
I yearn for the day that a viable alternative to play games on becomes available. Linux is not viable, I don't want to spend as much time configuring the game as I do playing it. I have nothing against Linux but it is not a substitute for Windows when it comes games. It's come a long way but it still isn't going to cut it for me.
