    Here is some more information. Seems the validity of the information is in question, but might be true.

    A (Terrifying) Traffic Analysis Of Windows 10

    The article mentions:
    Text "While the inital reflex may be to block all of the above servers via HOSTS, it turns out this won't work: Microsoft has taken the care to hardcode certain IPs, meaning that there is no DNS lookup and no HOSTS consultation. However, if the above servers are blocked via HOSTS, Windows will pretend to be crippled by continuously throwing errors, while still maintaining data collection in the background. Other than an increase in errors, HOSTS blocking did not affect the volume, frequency, or rate of data being transmitted.

    Wouldn't this render blocking all the domains listed in this topic useless? Or does the web proxy automatically do a DNS lookup for all blocked domains to block by IP as well?
