Hello,
Sorry for the noobish question, How do I stop XboxLive from Auto-connecting at startup?

I remember how to change it with the old dashboard, but now with the new dashboard my damn xbox360 keeps auto-connecting every time at start up.

Any help would much be appreciated

Thanks in advance!

Are you serious. Press the guide button and scroll across until you see profile, click on that and then auto sign -in. Disable and your done.

Just to let you know, if you're doing this because you don't want MS to see the backups you play, there's a rumor that the info is stored on the 360 and sent to xbox live whenever you go online.

Just make sure your games are properly stealthed and you should be fine.
