In my opinion, if those privacy issues bother you, the first step should be an overview of non-Microsoft operating systems.
and the alternatives are? osX invented all this. MS is just catching up. and apple don't even allow you to disable things. android? chrome alone sends more info than whole windows 10+edge. now, you could say Linux. but sadly your grand mother has no publicly available product she can buy with that OS.
I was pretty sure that I had disabled all my Mac's and iPad's "phone home" behaviours. (Of course, technically, iPad and iPhone are iOS, not OS X.) There are certainly a lot of dials to twiddle, but I thought that I'd hit them all and had found a reasonable amount of privacy (at considerable expense of functionality). What are the non-disable-able features?
