Windows Live ID™ Web Authentication Test
The text of the link below indicates whether you are signed in or not. If the link invites you to Sign in, you are not signed in yet. If it says Sign out, you are already signed in.
Please note, that if you sign out the Live ID logout screen may show a red cross icon that indicates the sign-out was not successful. That is usually not true. Do not click "repeat", just go on and finish back to this site. You'll see you have been signed out.
