They're going to keep supporting 7 for a couple years or so. 2020 at the latest, I think I heard, but eventually, yeah, there'll be a cutoff. Your OS won't die or anything, but virus protection updates and such will stop, and things will start to break down. I kept Windows '95 going on an old computer until 2010, and I could still do basic functions, but Youtube stopped working, and sites with lots of flash crashed the thing unless I adblocked the shit out of them. I jumped over to 10 to be ahead of that this time.
