Who the forget said anything about proving anything? I'd like to know the advantages of using Windows 7 over Windows 10, not some dude's vague description of why his computer doesn't work, which very obviously doesn't apply to me.
I don't think anyone's telling anyone you shouldn't use windows 10, and you certainly haven't asked anyone to explain to you why you shouldn't
you were pretty specific with your question:
What does Windows 10 break?
I still don't know what Windows 10 actually "breaks" (despite people explaining the problems they've had several times)
also, evidence is pretty much universally used to prove something, and that's one of the things you asked for, so I'd say it was you who said something about proving things
