Windows Messenger is a software of Microsoft that was included in the Windows XP operating system. It was originally designed for the use by the corporate users as well as home users to streamline and integrate MSN Messenger.  After its initial release in 2001, it was later upgraded in 2004, when it was made available for Windows 2009 and Windows Server 2003.

In October 2001 Windows Messenger was introduced with the release of Windows XP, and it was installed and enabled by default. It had a variety of features, such as instant messaging, presence awareness, and also support for (SIP) Session Initiation Protocol, which enables file transfer, application sharing and white boarding. Later versions added “ink” support and integration with Office Communications Server. These features were also exposed for applications to be used through a COM API called the Real Time Communications (RTC) Client API.

The release OF Windows Messenger for Mac 8 was officially announced by Microsoft. The company also stated that the software will be available as a free download or can be bundled in with Office for Mac 2011 making it easily available for its users and future clients.

The group program manager for Windows Live has given an statement saying that Messenger for Mac 8 provides a real-time collaboration between Mac users and their Messenger friends, whether those friends are using Messenger on a their laptops, phone, through Hotmail, or on another Mac. The user can use instant messaging, audio calls, and video calls to communicate with their Messenger contacts by signing in with Windows Live ID.

The software paves a foundation for real-time collaboration between Mac users and their contacts on Messenger. The drawback of this software is that it does not have support for social views and games, which are features present in its Windows version. The Messenger software is now available in Microsoft’s Web site.

Windows Messenger is one of the few outstanding releases expected from the largest software company Microsoft. The company had earlier launched the Office 2011 for Mac, which contains same features as software’s version for Windows. Microsoft Office 2011 for Mac will be accustomed with Word, Excel, PowerPoint, Messenger and Outlook.
