Forget the Turing test, now that Microsoft has brought out Cortana to rival Apple's Siri, leave them alone in a room together and eavesdrop. If between them they can initiate a conversation and keep it going for 10 minutes, then I am willing to consider that they have artificial intelligence.
A friend of mine asked Cortana how to uninstall itself. It gave no answer. I suggested he look at Asimov's Laws of Robotics. Perhaps Cortana's inaction was intended to prevent my friend from coming to harm.
