The social networking giant, Facebook has officially launched Messenger for Windows and the newly introduced app lets you chat, receive notifications, and read your news feed from your desktop without being on www.facebook.com. You can set up the app if you use Windows 7 on your computer. According to Facebook, this app does not support Windows XP and they are currently working on a version of this app for Windows Vista.
The app will be rolled out to users’ profiles over the next few weeks. However, you can download the app - Facebook Messenger for Windows 7 - from https://www.facebook.com/about/messenger.
Chatting with multiple friends, video calling, limiting chat availability and editing settings are not currently available through the app. You can still do these by going to www.facebook.com in your web browser.
