As of January 14, 2020, your computer running Windows 7 will still function but Microsoft will no longer provide the following:
Technical support for any issues
Software updates
Security updates or fixes
Aye, I don't use win7 because it's unsupported. Microsoft also updated it automatically when I wasn't looking.
I don't really care enough to support windows 7 myself; as I mentioned, the only reason I have Windows is for video games, so as long as I'm still getting video driver updates, Win10 could be the worst OS in the world and it wouldn't bother me too much.
