XBox can be connected with a Windows Computer using Windows Media Center. This requires an 8 Digit secure key using which Windows Media Center adds the XBox 360 console as extender and lets you play movies, videos and images on your TV. So anybody who knows this key can add your XBox as one of its extender for example lets say one of your friend or family members want to play a movie which is stored on their laptop. This is a privacy concern if not a security issue.
Changing this setup key can help you resolve this and you can do that in two ways :
- Change the IP address of the XBox 360
- The settings can be found in MyXBOX > System Settings > Network Settings > Available Network > Configure Network > Select the already available IP and change to manual
- or Clear the network settings i.e. if it is connected to Wi-Fi router, remove the settings and add it back.
- The settings can be found in MyXBOX > System Settings > Network Settings > Available Network > Press Y to Disconnect and connect back later again.
