I doubt you could with Windows Firewall, but my firewall (Comodo) seems to do the job.<p>You can find all the known domains and addresses for the Microsoft telemetry and advertising networks through some searching online. I added them all to my hosts file as well as block lists in Comodo Firewall.<p>I did both because I assume Microsoft has wired access for some of these services in such a way that the hosts file would be ignored, as well as Windows Firewall.<p>I have my firewall also set to request user action on EVERY outgoing connection (all incoming stealthed, so no open or closed response) and so far all I have allowed out in terms of Windows processes is Windows Update. I haven&#x27;t even allowed the error reporting.<p>The OS is still ticking along just fine.<p>Honestly though this whole approach they ahve taken with Windows 10 has really turned me off. It reeks of anti-consumerism. I basically just use this Windows 10 machine as a gaming machine now, and all my personal and professional computing is done on a separate Debian machine.<p>Microsoft won&#x27;t be getting another penny from me for anything ever again.
