Windows Media and DVD's

Just got a new laptop from my job (Toughbook CF-29) w/ the DVD drive on it. Of course I've tried to play DVD's on it and they have blocked playback. Does Windows Media play DVD's (store bought & DVD-R)? If so, how do I change the settings on it?

I tries to install Interwin DVD (or whatever it's called), but it stopped me from putting it on there...

Thanks for the help, obviously I'm not an IT guy.
