That is putting a lot of faith in both Microsoft and the windows firewall, which has historically been very weak.  Microsoft has also indicated that they&#x27;re not adverse to bypassing users&#x27; obvious attempts to protect themselves from spying, for example: bypassing hosts file entries for telemetric data exfiltration.  So while the firewall might work today, there is absolutely nothing preventing a future update from silently changing the rules of the game.
