Windows Messenger vs. MSN Messenger

Both Windows Messenger and MSN Messenger are Instant Messaging (IM) client applications. Although there are some distinct differences between the two applications:

Windows Messenger is an IM client designed for use in a business environment. This client is designed to communicate with Microsoft's Office Live Communications Server 2005 server, as well as communicating with MSN Messenger. Windows Messenger communications is also encrypted.

MSN Messenger is designed for use as a consumer IM client application, that can only communicate with the MSN Messenger Service. Communications with this client is not encrypted, as they are with Windows Messenger.
