About Linked IDs

If you have a Windows Live ID that you use for work and one that you use at home, you can link them. When you link more than one Windows Live ID, you can sign in to a Windows Live site or service with one account and still have access to information related to the linked accounts.

Basically it allows you to have access to both ID's and their respective contact lists etc, while signed in with one of them.
