Microsoft's privacy policy reflects the fact that Microsoft has to comply with the most conservative interpretation of the most restrictive privacy regulations from the set of all privacy regulations found anywhere in the world. It amounts to "Microsoft does not guarantee privacy." The reason is that Microsoft cannot make such a guarantee because of the diversity and strength of privacy regulations.
I'm not saying that strong privacy regulations are a bad thing or that Microsoft's policy is a good thing. Just that Microsoft's policy reflects reality where competitors and activists and politicians are inclined to use privacy regulations for purposes orthogonal to any actual concern about privacy. The connected world is full of caches and Microsoft does not control them. Users can do stupid things that Microsoft cannot prevent.
Agree with the terms and use Windows. Don't use Windows if you disagree. The website hosting the blog runs google-analytics by default. It doesn't ask my permission. It runs Disqus by default. It doesn't ask my permission. The privacy badger ate too many cookies and died years ago. Microsoft is late to the wake.
