Are you joking? Even as a casual users, when would you ever run
Windows without networking these days???! I don't think you can even
buy a computer without networking any more :-)
Even just to transfer files from host to guest, you'll typically use a
network.
Or do you mean something else by "networked images" in a company context?
Fwiw, when I have done Windows migrations for companies, they never
have MSDN subscriptions (and neither do I :-) They have purchased
Windows with the machines, and later they want to migrate those
machines into VMs. No hint of MSDN anywhere, why would they?
