Windows Messenger is a discontinued instant messaging client included in Windows XP. Designed for use by both corporate and home users, it was originally created, in 2001, as a streamlined and integrated version of MSN Messenger. It was upgraded several times when it was made available for Windows 2000 and Windows Server 2003. Since then, its development stopped. It was superseded by Windows Live Messenger and Microsoft Lync.
