What is the Default subscription? What is it used for? How do I change it?
If you have more than one TechNet Subscription, one of them will be the default subscription.

Change the default subscription on the Manage My Subscription page (http://technet.microsoft.com/subscriptions/manage) by selecting a new subscription from the drop-down list and click the default button.
