In Windows Media Player you can toggle between two modes: the Player Library, which gives you control over the Player's many features, and Now Playing mode, which gives you a simplified view of your media that's ideal for playback.
From the Player Library, you can go to Now Playing mode by tapping or clicking the Switch to Now Playing button in the lower-right corner of the Player. To return to the Player Library, tap or click the Switch to Library button in the upper-right corner of the Player.
In the Player Library, you can access and organize your digital media collection. Within the navigation pane, you can choose a category, such as Music, Pictures, or Videos, to view in the details pane. For example, to see all of your music organized by genre, double-tap or double-click Music, and then tap or click Genre. Then, drag items from the details pane to the list pane to create playlists, burn CDs or DVDs, or sync to devices, such as portable music players.
As you move between views in the Player Library, you can use the Back and Forward buttons in the upper-left corner of the Player to retrace your steps.
In Now Playing mode, you can view DVDs and videos or see what music is currently playing. You can decide to view only the currently playing item, or you can swipe or right-click the Player, and then click Show list to view a selection of available items.
