I keep all my essential data on external hard drives. Bit of a hold over from when I was carting films/music from place to place and it easier/safer/more reliable than carting the whole tower over. So even now, I keep as much as I can on *not* the system disc.
But I am talking from 2 laptops (one is 2-3 years old, the other is coming up to its 6th anniversary and just about runs windows 10 (but better than windows 7 on it)), a linx tablet, and my main desktop (along with another laptop in the house that isn't mine).
But as others have said, this happened to Windows 7 just last year (which I somehow avoided getting caught in... *shrugs* I was on Windows 8 then, so I guess that is how I missed it)
But yeah... Somehow I have this knack of avoiding a lot of the issues that other people seem to stumble into every 10 seconds or so... I have no idea how, maybe my name should be Lucky.
But then I would get dragged behind the toilets and shot.
