Windows doesn't automatically die when it reaches EOL/EOS [End of Life/End of Support], just won't get security updates which will put the computer at risk of disastrous infections. Same for features, no updates or new ones. I'm keeping a Win7 Desktop running as long as I can keep the AntiVirus program up to date. And No, those things also will not receive updates when Windows support ends, programmers won't get backup support.
