Re: Windows 8 - Looks really awsome You are paying for using Windows, you're not paying for playing every multimedia file in existence on the built-in WMP -- because Microsoft is not selling such "universal" feature neither making propaganda about it. (check what Microsoft states about WMP. Did you read some false propaganda?) But you can play .avi and .flv in WMP - just add some third-party codec pack. There is no built-in restriction to codec packs. Heck, Microsoft explains that too.
