According a link shown in the FB messenger App, it would shut down from March 3. "We're sorry, but we can no longer support Facebook Messenger for Windows, and it will stop working on March 3, 2014. We really appreciate you using Messenger to reach your friends, and we want to make sure you know that you can keep chatting and view all your messages on http://www.facebook.com," the message stated at the top of the application.
