I'm afraid there is not, Windows Live Messenger which used to be MSN Messenger, dropped the
SIP functions back in 2002 (version 5). It is purely a consumer product.
The SIP functions from Windows Messenger were spun into Office Communicator and you'll need
to use that if you wish to connect to SIP-based communications services in Vista.
