Appear offline to individuals or categories

Windows Live Messenger allow users to appear offline to particular individual contacts, as well as to an entire category within Windows Live Messenger, while appearing online to other contacts.
This is a recent feature of Windows Live Messenger 2011, and is a departure from the previous versions of Windows Live Messenger, where blocking a contact would prevent the "blockee" from sending the user any messages to the "blocker". With the "appear offline to" configuration currently implemented, "hidden from" users can still send "offline messages" to the target. This change has caused some uproar among users.

Social networks integration

Additionally, Messenger also imports all contacts from the connected services and integrates with Facebook Chat (via the XMPP protocol) for instant messaging support with users on Facebook.

Offline messaging

One can send messages to contacts who are offline; they will receive the messages once they come online. Additionally, a user can start conversations even when his or her status is set to Appear Offline in Windows Live Messenger 2009 or before.

Games and applications

There are various games and applications available in Windows Live Messenger that can be accessed via the conversation window by clicking on the games icon, and challenging your friend or contact to a competition in a game, or inviting them to launch a shared external application.

MSN Messenger

Before the product was renamed Windows Live Messenger, it was named "MSN Messenger" from 1999 to 2006. During that time, Microsoft released seven major versions as follows.
The first version of MSN Messenger Service, version 1.0 (1.0.0863), was released July 22, 1999. It included only basic features, such as plain text messaging and a simplistic contact list. When it was first released, it featured support for access to America Online's AIM

A minor update, the Windows Live Messenger 8.1 Beta 1 Refresh, was released on December 13, 2006, and fixed bugs that were causing some people to be unable to sign in and others unable to see their contact list.

The final version 8.1 was released on January 29, 2007. No changes were made from the Beta 1 Refresh. All versions of Windows Live Messenger below version 8.1 were rendered obsolete on September 12, 2007, due to a security issue identified when a user accepts a webcam or video chat invitation from an attacker.

On September 12, 2007, the Windows Live Messenger blog posted a fix that resolved a security problem. It reported of a security vulnerability in versions of Messenger older than 8.1, that the released fix would resolve. This led to an auto-update being released to all older versions. Versions running on Windows 2000 and below were required to update to a new version of MSN Messenger 7.0, and versions running on Windows XP and above were required to update to Windows Live Messenger 8.1.

On August 27, 2009, the Windows Live Messenger blog posted that due to a security problem, all users of versions 8.1 and newer need to update to the latest version, 14.0.8089. The mandatory upgrade requirement will be fully phased in by late October 2009 and began on September 15, 2009.

Microsoft began the official beta program for Windows Live Messenger 2009 on September 17, 2008, when it released a new beta officially known as Windows Live Messenger 2009 Beta (Milestone 3, Build 14.0.5027.908), which was made available to the general public as a free download. The ability to submit feedback, however, was restricted to select participants of the Microsoft Connect closed beta program.

Notable changes in Milestone 3 include a new revamped and refined user interface to follow suit with the rest of the Windows Live "Wave 3" design, the ability to set a "Scene" by customizing the background image and color of the contact list, and the display of these scenes in conversation windows for improved contact identification and window management.

Milestone 3 also brings a new "Groups

" feature that allows users to create a continuous group conversation between select contacts, newly redesigned status icons which now resemble small gems rather than the previous "Messenger Buddy" icons, a new default "Favorites" category in which you can place your favorite contacts for easy access to them, a new Photo Sharing utility that allows contacts to quickly and easily browse photos together, and a "What's New" section at the bottom of the contact list to outline recent contact updates. Display pictures have been moved over to the left side of conversation windows, and new colorful borders appear around display pictures to display the current status of that contact.

. This version saw a removal of the custom sign-in sound feature however it is still possible to select a sound for other individuals, as well as changes to how the background image chosen is applied to the conversation windows. This build also included over 200 bug fixes including the "Custom Emoticon Bug" and saving of pictures when using the Photo sharing feature. On January 7, 2009, the same build was released as the final version of Windows Live Messenger 2009.

The last QFE update for Wave 3 was released on May 12, 2010, and saw the removal of some features from Windows Live Messenger. Specifically, the ability to independently show only your own webcam or your contacts' webcam (one way webcam) and without an audio call is gone. It is only possible to start a video call which starts the webcams of both people communicating and which also automatically starts audio calling. Also removed is the ability to import and save/export instant messaging contacts to and from .CTT files.

Windows Live Messenger 2011 (Wave 4)

In late March 2010, a beta of Windows Live Essentials Wave 4 was leaked onto the internet and has since spread to various BitTorrent networks, which included a private beta build of Windows Live Messenger Wave 4. However, as the software was designed for private beta testing, non-beta testers cannot sign-in to this leaked build.

The new software features a revamped interface which brings the "What's new" section of Windows Live to the new "social pane", similar to the way a social networking site presents updates. Among the new features are tabbed conversations, a redesign of the old emoticons, integration of Bing results, built-in video message

However, several features had also been removed from the previous version, such as the removal of display names, handwriting tool, one-way webcam requests and import/export of instant messaging contacts feature. The "Wave 4" release of Windows Live Essentials, which includes Messenger, also dropped compatibility with Windows XP

"i’m" initiative

The i’m initiative was a program Microsoft launched in March 2007, that connects the user with ten organizations dedicated to social causes through Windows Live Messenger, only for conversations sent or received in the USA. Every time someone had a conversation using i’m, Microsoft Corp. shared a portion of the program's advertising revenue with the organization of the user's choice. There was no set cap on the amount donated to each organization. The more i’m conversations the user had, the more money went to one of the ten causes. Each participating organization was guaranteed a minimum donation of $100,000 during the first year of the program. The i’m initiative worked with version 8.1 and above.

On March 2010, the initiative concluded, having raised over 3 million dollars.

For this reason, features that fall outside of that scope, such as games or the new social views available in the Windows Live Messenger 2011, will not be available for the Mac.
