No, this is not the full version of Angry Birds. As far as I know, the Angry Birds game is on a shareware licence if you want to play it as a standalone Windows/Mac application. It's free on Facebook and other supported platforms (eg. Android, iOS). However, there are many variants of Angry Birds and they're free or shareware, but this particular one is not full.
