Answer:
Go to My Xbox and open your profile.
Select Join Xbox LIVE.
Follow the directions on the screen. Here are some tips to help you out:
You need an e-mail address to create an account. If you already have a Windows Live Hotmail account, Live.com account, Xbox.com, Zune, or Games for Windows – LIVE account, pick one of those. If you don't have an e-mail account, you can get a Windows Live Hotmail account for free.
Use your real date of birth; we use it as part of the verification process when creating your account.
When you enter info like your address and name, you can use your Xbox controller or a USB keyboard.
If you choose a Gold membership, we'll charge the credit card number you give us. If you sign up for a Silver membership (which is free), we won't ask for your credit card information..
Connecting to Xbox LIVE involves three basic steps:
Connect your Xbox 360 console to the Internet
Test your connection
Join Xbox LIVE
First we need to know how you want to connect your console to the Internet.
Select your connection type: Wired Connection, Wireless Connection, or Modem connectionn
