HOW TO CHANGE THE NAME OF YOUR XBOX
Naming your Xbox is a simple task. All you need is the right game. Almost any game that lets create your own character then name it, or add your name to the high scores will work. The maximum number of characters is eight. So if the game limits you to eight characters it will probably name your Xbox. Most times you see your name is when you play on a lan. In Halo when you play a system link game it will show the name of the other persons Xbox at the joining game screen. If the Xbox hasn't been named yet it will maintain the random defalt name it was given . These same random names are used in Halo multiplayer when defalt is picked.
