Windows Live
In September 2007, Microsoft began developing a new version of the service named Windows Live Web Messenger. This version was released to internal beta testers and was not available to the public. Windows Live Web Messenger featured the "Windows Live 2.0" user interface, integrated Personal Status Message and display picture functionalities, and allowed tabbed conversations in a "conversation workspace". Windows Live Web Messenger was officially discontinued on October 30, 2008 and its capabilities were integrated into Windows Live Hotmail and Windows Live Contacts. However many functionalities in the beta version of Windows Live Web Messenger, such as tabbed conversations, were unavailable in the Windows Live Contacts and Hotmail version.
