Win8/8.1 is good till 2023
That's hilarious. Put in a current amd or intel cpu and see how long it's supported for, you get the big upgrade thug message. They ended win8 support last year based on that alone. Thankfully there was a 3rd party fix. And yea, I like being able to ignore updates or chose not to install them.
I don't know why you would use 8/8.1 over 10 but, to each his own I guess.
The question should be why are you using win 10 over win 8? Thought there were enthusiasts here, not take it in the arse I've given up and am thankful for your scraps.
