Facebook has begun testing an instant messaging application that currently only works on Windows 7. The  application gives you instant access to three basic functions: Facebook Chat, Ticker Feed and status updates.

Facebook writes the following on the official website of the new application:

Messenger for Windows is a new trial application that lets you use Facebook without being on www.facebook.com. While you surf the web or use other applications on your computer, you can:

  • Chat and message with your friends on Facebook
  • See the latest updates from your friends in ticker
  • Get quick notifications about what’s going on

Facebook does not state when the program is scheduled to be completed, or if there will be versions for Mac or Linux made available later.
