Reference Manual for Windows Media Player

Windows Media Player

Windows Media Player has multiple different versions.

Here, we provide class IDs for different versions and parameter lists.

Why does the class ID change?

The class ID for Windows Media Player 7 and later versions is:clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6.

Many places on the Internet declare the class ID as:clsid:22D6F312-B0F6-11D0-94AB-0080C74C7E95. This class ID is an older version but still functional due to its backward compatibility. However, if you use the old class ID, you cannot use new features added to the component.
