Because I'm in Canada I can't access Cortana (Edit: yet. We're in the next batch of countries to get her supposedly). Not sure what she can/does respond to. Is she always-on? Thus can you talk to her/it at any time, in any game if you have a mic? Or only if you click something is she set up to respond?I believe it's anything you type that you have Cortana enabled to respond to, because that text goes to Microsoft to process what Cortana will do.
