Update: Facebook has asked us to provide this official download link for the application here.

The Facebook Messenger app for Windows has been leaked early while the company is testing it with a limited group.

TechIT.co.il, which discovered the leak, points to the file.

Here’s what the app looks like:

The app lets you use Facebook without actually being on Facebook.com. You can chat and message friends, see updates from the ticker and get notifications while your browse other parts of the web.

“We’re testing out a first version of the app with a small group of people,” says Facebook. “During this trial period, we plan on rolling out changes to the app and expect outages and periods of instability as we make improvements.”

The app works with Windows 7, and updates will be installed automatically.

You can log in and out by right-clicking the Facebook icon in your Windows system tray.
