The messaging application Facebook Messenger which iPhone and Android users have been enjoying for a few months now is also available for Windows 7...For those who do not know, this is a very useful application that separates the chat function of Facebook from Facebook itself. In other words, the application allows you to communicate with your friends on the social network without the need to even open your browser!
More specifically, you can chat or send messages to your friends, see their latest updates at the top of your online contacts (just like in Ticker) and receive your Notifications.
You can download the application from here, while you do not need to worry about future updates since everything is done automatically.
