Facebook's Messenger app for Windows is now available for all to chit-chat with. Facebook has been testing the application since November as part of a private trial, but TechIT revealed the download link on Thursday. The application includes access to the chat, ticker feed and notification parts of Facebook, and only installs on Windows 7.

The app forms the latest in a series of standalone Facebook chat applications made available earlier this year. Facebook has previously released apps for iOS, Android and BlackBerry to enable users to chat on the go. The Windows 7 app doesn't take advantage of the unique pinning features of the operating system, but it does include a neat dock feature that will snap the app to the side of the screen. If you're a Facebook chat addict then hit the source link to give it a go.

Update: Facebook has responded to the leak by officially releasing the application, and updating their support pages. "We encourage readers to learn more about the app in the Facebook Help Center here. They can also find the official download link within the Help Center or at the link here," said a Facebook spokesperson in a statement to us on Friday.
