While I appreciate the research you put into this article and I upvoted it for your work, I don't agree Microsoft is heading in a great direction, and I especially think Windows 10, apart from DirectX 12 (which they decided not to make compatible with W7...) is a huge step down from Windows 7 and it just completely shits on your privacy, even if you change all of the privacy options. Not to mention it was a bug-infested piece of crap at launch.
Also, intentionally, most new laptops and computers are not compatible with Windows 7, forcing you to use 10. You can get 7 working on some of them, but the average user has no chance of doing it.
