Does the method of blocking internet access (but allowing intranet access) on a PC by changing the IpV4 protocol properties to a static IP equalling the IP address of the PC (in place of the automatic assignment from the DCHP) ALSO prevent Microsoft's (or another vendor) from accessing the machine? The goal here is simple - once I have the installation working as intended - I want to prevent ANY updates of ANY kind from ANY one. Since the computers wont access the internet I wont be concerned with security or software updates. I SIMPLY WANT THESES CLOWN TO LEAVE MY MACHINE ALONE. OR, does this method not prevent access TO THE machine FROM the internet? Ancilliary to that - does Microsoft have some other way to access the machine? I get it - just unplug the network cables -- but I still want intranet access - and I will leave one machine with access for email and uploading to my cloud service.
