I am trying to block all connections to microsoft ip addresses. I only occasionaly boot windows and don’t want it phoning home. I tried disabling the net interfaces in device manager but windows just re-enables them and send god only knows what back to their servers. I don’t like relying on disconnecting the ethernet cable each time I boot windows because I forget to.
Ok, so i guess you’re dual boot. So in Windows, Device manager, find your network device and disable it there. It shouldnt ever reenable itself on its own.
Microsoft IPs blocklists exist, though I havent used them. I imagine they update frequently. Adguard home or pihole have good uses but itll need an always on device to run it.
A simpler idea which should be a 20 minute turn around to do, amd will cost you nothing would be either:
Yes, dual boot. It is a Dell Optiplex. Windows re-enables devices disabled in device manager.
