Windows 8.1 is finally here
– and it even brought a few friends
to the launch party, including a new official Facebook app for Windows. The app brings you all the familiar features you’d expect, plus some cool extras that are unique to Windows. Live tile notifications give you an at-a-glance summary of post and message activity right on your Start screen. Use Facebook side-by-side with other apps and programs for easy multi-tasking. And the Windows People Hub integrates seamlessly and automatically with your Facebook contacts.
