Facebook CEO Mark Zuckerberg said back in October that the company was "all in on Windows 10." After months of beta testing, Facebook is launching its new Facebook and Messenger apps on Windows 10 today. While Facebook already has an existing Windows 8 version of its desktop app, today's release brings it in line with iOS and Android versions thanks to some feature additions.

Reactions, stickers in comments, and a column for birthdays and event reminders are all present, and Facebook has even created a built-in browser to convince users to share articles to their News Feed. Live video broadcasting isn't supported just yet, but it should be arriving shortly.

On the Messenger side, the Windows 10 app is exactly what you'd expect. Messenger for Windows 10 has native desktop notifications, which means that messages will appear in the Action Center. Messenger for Windows 10 also supports photo sharing, stickers, group conversations, and GIFs. It essentially looks like a packaged version of Facebook's Messenger web app, but it's a native app with support for Windows 10's notifications. Payments, voice / video calling, and taking new photos / video in the app aren't supported at launch, but Facebook will be updating Messenger over time.

While both the apps launch for Windows 10 desktop today, they won't be available on Windows 10 Mobile just yet. Facebook and Messenger are arriving on Windows 10 phones "later this year", according to the company. Both the new Facebook and Messenger apps for Windows 10 are rolling out today, but it may take some hours before they're fully live in each Windows Store worldwide. Facebook is also announcing an updated Instagram app for Windows 10 Mobile today.
