I logged into xbox with my windows live id. I had never done this before. When I logged in it had a very strange gamertag name for me. I never had created it. It was just there. Is that because xbox creates a random name for my first joining?
Please check on your XBOX 360 for your current XBOX 360 Gamertag by going to My XBOX > Select your Gamertag Avatar > Account Management - you should see Windows Live ID listed there. You have to login using that e-mail and password to the XBOX.com website.
If you want to change it to a different e-mail address then please follow these instructions to do so:
