If you have facebook(even if you do not post anything there), and you hangout with friends which took a lot of fotos and post it or just tag you as company somewhere you already lost your privacy. That part with information gathering with win10 from M$. Daily I use win10 for work and I don't have anything to hide on it(of course I switched of all that shit which was sending info to M$ which I could). I do not live in country where my secret service spy on citizens, they are faggots and don't have money on it
I just don't buy it. If I want stay anonymous with something I just switching on VM with linux and use all that power of TOR, porxychains and vpns. Mayby somewhere else like Murica, Britain or Germoney, you are scary of this shit. And if I have any secrets, I keep it far away from computer connected to the net. That is just only my opinion.
