You might be using third party Facebook chat clients for Windows like fTalk, Windows Live Messenger, AIM or others to directly access Facebook chat from your desktop. Noow you don’t need to rely on third party apps because Facebook has now released its very own messenger for Windows PC.
Facebook messenger enables you to chat with your online friends, shows your friend’s recent activity in the news ticker, shows notifications for friend requests, offline messages and main notifications in the bar at the top of the app. The messenger only works as an intermediate, for example if you click the notification in the messenger then the content will open in the browser instead of the app.
The desktop messenger can either stay float on your desktop or can be snapped to the desktop’s sidebar. Its a light weight app and tries to provides you all the major features as in the browser version. The messenger gives one more reason to stick with Faacebook.
You can download the messenger for Windows 7 from Facebook help center or use the link below for direct download.
