James Skemp's StrivingLife

Shortly after logging into Xbox Live the Xbox 360 will attempt to log into Windows Messenger, by default.

While I tried to find how to disable this, all of the articles I found were irrelevant, since they were written during the 'blades' interface.

Here's how I stumbled on it.

1. Press the Xbox button on your controller.
2. Go to the Settings tab.
3. Select Profile.
4. Select Auto Sign-In.
5. Select Disabled under Windows Messenger.

For some reason I had to do this a couple of times for it to stick.
