Facebook Messenger for Windows is the official program for Facebook that allows you to chat with your contacts from your desktop.
Facebook Messenger for Windows not only lets you communicate with your Facebook contacts but also gives you access to your news feed and message notifications giving you access to all the essential tools of the Facebook social network.
The interface of Facebook Messenger for Windows is very clear and divided into two separate windows. One is dedicated to contacts and feeds like the right column of Facebook and the other opens chats. Any notifications appear as pop-ups on your desktop.
Note that although this is the first official Facebook desktop app, there are already several programs that allow you to chat with Facebook contacts including Digsby Trillian Astra, Nimbuzz and Skype.
