Win 10 is way after my time. When I was the SQM architect we were very strict about not collecting any identifying information, the collection was always opt-in, and the intention was to publish a KB article with a list of the data points we collected (not sure if that happened). I don't know what the internal MSFT rules are now, but the conservative position I took back then does seem rather quaint given what happens on mobile platforms nowadays...
