I am setting up a new PC for my small office network. Other machines on the LAN are XP/Win7. I keep the gateway settings blank on these PC's to prevent it from accessing the net, while the machine is still available on the LAN. Is this a good way of preventing net access. The users are standard users so they cannot change settings, only I can by going into admin account. Can I do the same thing on Win10Pro PC or will it create problems? Does Win10 need internet access to function?
