How To Play DVDs on Windows 8
 

Upgrade to Windows 8 and you may be surprised to find that you can no longer play video DVDs. Unlike previous versions of Windows, Windows 8 doesn’t include built-in support for playing DVDs.

Microsoft opted not to include DVD support because so many new computers – especially tablets and ultrabooks – aren’t coming with DVD drives. Microsoft pays a licensing fee for each copy of Windows that ships with DVD support.
