Your Win7 screenshot shows just a nice green shield next to the preselected default setting, and a scary red "X" next to the one that would prevent Win10 from being downloaded. The 3rd option also says that you will be vulnerable if you select it.
Finally, nothing on those screens says anything about automatically downloading a different OS. There's zero consent to that.
It's not a different OS it is an upgrade, and the scary red "X" is valid and not a scare tactic. I deal with people on a regular basis that are still running XP, which leaves them vulnerable to attack and infection.
In the always connected world that we live in, automatic updates are a very necessary fact of life.
