How To Enable Xbox Companion in Windows 8
One thing Microsoft definitely is trying to get right with Windows 8 is the integration with Xbox. At the moment, this integration is minimal, but you can definitely see where Microsoft is heading with it: allowing you to play Xbox games from the console on the PC, pausing and resuming, etc. They aren’t there yet, but there are still some fun things you can do like control the Xbox using your PC.
Before you begin, make sure you are logged in to your Windows 8 PC with the same Windows Live account that you use on your Xbox and that both your Xbox and PC are connected to the same Wi-Fi network.
1. Launch Xbox Companion from the Metro start screen.
2. Turn on your Xbox 360.
3. Go to Settings > System > Console Settings.
4. Select Xbox Companion.
5. Select Available in the Xbox Companion Settings.
6. Click Connect on your PC.
