What's the difference between MSN Messenger and Microsoft Messenger?

[Dyne]

Microsoft Messenger is the effing annoying version, standard in an install of Windows XP, that won't stop connecting when you turn to alternate sources of internet in foreign places, logging you on and having people message you "WHERE ARE YOU?" only to drive you mad and wish you'd told them about you leaving.

MSN Messenger is the good version that actually listens and doesn't boot up randomly and run in the background even after you tell it not to, 5 times.
