Microsoft do rather miss the point
There is no need to separate data into 'necessary' and 'nice to have' or indeed any other category. In particular, the user should have no need to plough through a maze of twisty little passages, all alike, just to try and decide which of his data he will be allowed to (allegedly) keep out of MS's sticky little fingers.
There should be exactly *no* data flowing from you to an OS maker unless and until you explicitly request it. It's that simple. MS have no need to know what programs I am running, how big my disc drive is, how slow my processor, what I'm searching for and where, my location, the weather, how much uptime I've had, what's in my documents... nada, zip, zilch.
It's that simple. There should be an expectation that anything I do with my computer is between me and the computer, and maybe a website owner. We've spent years being sucked into the expectation that all is funded by advertising, and that data must be collected for our comfort and convenience, and now we're presented with this bullshit?
Nah. -->
