Separate Window Plug-ins
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
Separate window UI plug-ins are shown in their own windows. These windows can be fixed in size or can be made resizable. Multiple separate UI plug-in windows can be open at the same time.
Separate window UI plug-ins are useful when you want the information or controls you provide to remain visible when the user switches out of the Now Playing pane or loads another UI plug-in. Any separate window UI plug-ins that are running when Windows Media Player is closed will be reloaded and displayed in the same size and position when the player is started again.
