"Breaking" in that sense isn't the same as in the sense my posts are talking about.

It's "breaking" in the sense of compatibility. If an app runs on Win 7 and Win 10, Win 10 didn't break compatibility between Win7 and Win 10 because an upgrade doesn't go through properly.

And while I have heard plenty of issues with upgrades, I've also personally had 0 issues with them since 7, on any of my personal machines, even some in the insider track.

Even in the thread you link to almost every other response is in line with what I mean: "it's usually very very hard to accidentally make a program run on Windows version N but not on Windows Version N+1"
