Yeah, that means it will get increasingly risky to use it for web surfing.
But the fact that after many years of pushing Windows 10 down everyone's throat, Win7 still has half of the Windows user base, means that a heck of a lot of people are more than willing to take that risk.
Not sure I would want to continue using Win 7 for any bank or investment account when the security patches stop.
I would strongly recommend against it. Then again, I wouldn't use Win10 either. Personally I use non-Windows systems for financial or other critical online work. Smaller attack surface and far fewer active exploits in the wild for Mac and Linux.
I love Win7, and will not voluntarily switch to Win10 except for compatibility testing of my software. When I think Win7 have at last run its course, I'll be using Mac and Linux systems for anything that doesn't absolutely require Windows. Sad, but true.
