Windows Media Player has four display modes: Player Library, Now Playing, skin , and full screen. You can easily switch to the mode that works best for the content you are viewing or playing.
Now Playing mode has a simpler interface that's optimized for playback.
The Player Library provides access to nearly all of the Player features.
Skin mode allows you to use a customized, alternative view of the Player.
Press Ctrl+2 to change the Player to display the most recently selected skin.
Right-click anywhere in the Player except the menu bar, and then click Switch to Library.
Full-screen mode makes videos, DVDs, and pictures fill the entire screen when you play them.
View a picture or play a video, TV show, DVD, or song.
You might need to resize the window to expose the View full screen button.
To return to Now Playing mode, press Esc. For more information about full-screen mode, see View a video using the entire screen in Windows Media Player.
