Facebook launches a desktop app for Messenger on both Mac and Windows. A look at the good, the bad and the promising.

Facebook Messenger allows you to chat with Facebook friends while on the go. Here's how to download it and why you should use it over the web interface.

Windows Phone users eager to download Messenger should make sure to disable Facebook chats in Threads, otherwise they’ll receive duplicate messages.

By late 2016, you’ll no longer be able to download and install the app, and on Windows the app will cease to function in early 2018. If All-in-One Messenger appeals to you, download it ASAP.
