  You mean EternalBlue? How exactly is a remote attacker going to use a vulnerability in a local networking protocol to attack a typical home user's PC? First you need a way into their network where you can even see the PC to attack. If you have that then you're already dangerous. As I said before this kind of vulnerability is still a concern. Obviously it's a much greater concern if you're talking about something like a laptop that might be connected to an untrusted network, which would be crazy with an unsupported or unpatched OS. But for a home user who stays on their own network it's probably quite a long way down the list of things to be worried about.
