Windows 7 will still work after 2020. There's no magical "shut it down!!" switch that makes it stop working in 2021.
Well, duh!
But who will support it, still?
I mean, which developer not totally out of his mind will officially still support Win7?
Answer: No one will.
At some point (might not be 2021, but who knows, really), Win7 simply won't be compatible any more. Bugs that appear on it with software X won't be fixed any more.
You're piloting a derelict ship by then.
This is exactly the same kind of bullshit that happened with WinXP.
Back then, some people didn't switch for the exact same reason: Pure stupidity. "I will never switch" "Fuck MS!" "Shitty malware" bla, bla, bla, bla...
And now, large parts of software simply don't work with it anymore. Notice how WinXP has completely disappeared from the internet, except as a solution to run old games in a VM.
Well, okay, there was Vista, and Vista was just a really bad piece of software - but Win 10 is the "best" Windows so far, no complaints except some conspiracy theories*. Of course, this place is full of retards like that, so I'm not surprised in the least by this butthurt
*Well, no complaints compared to other Windows versions. There are still dozens of big problems with Windows in general.
You can't disable any of it because it
1) Either re-enables itself automatically or;
2) The switch doesn't actually do nothing and it's just placebo
Watch out, man, they are right behind you!
