Powered by Windows 10, the new dashboard includes features that focus on speed and performance, and a design that's a lot more simplified.
One of the key new features in the Xbox One dashboard update is Cortana integration. You can say "Hey Cortana, record the last minute and share it to my activity feed" and it will publish a game clip straight away. Likewise, "Hey Cortana, start a party and invite Amanda" will invite a friend into a voice chat all without having to lift your fingers from your controller. Cortana will require the Kinect sensor for audio controls.
