Well I would hardly say that protections against being obliterated in a global ransomware attack that comes out after the ransomware attack occurs helps the victims that much but yes it is possible if there is another massive cyber attack Microsoft could release a fix for 10 years after support has ended.
It is definitely possible to heavily lockdown a Windows computer to prevent 99% of attacks and if you don’t need WAN access especially that becomes significantly easier.
It is far more likely browsers will drop support for 10 in a few years and that will be what stops the average user from being able to continue to use their Windows 10 computer.
Ah, I missed the part where the vuln had already been patched for newer versions before it was patched for XP, it's just that many didn't install the patches. Although, the exploit happened to not be compatible with XP just because the creator didn't bother. Security through poverty (jk)
