Well I found a video on YouTube promoting MSN 11 Beta and I decided to try it out. It didn't show as a virus as anything and seems real. It asked me to enter my login and password and there were options for 'Remember Me', 'Remember My Password' and best of all 'See Who Has Blocked me.' I'm guessing that WLM 2010 is nearly finished so it would make sense to start work on WLM 11 although it doesn't seem to login.
For anyone who's curious
