Windows Media Player 11 cannot play DRM-protected content on Windows Vista

You may be unable to play Digital Rights Management (DRM)-protected content in Microsoft Windows Media Player 11 on a Windows Vista-based computer. When you try to play DRM-protected content, you may experience the following symptoms:

• You receive the following error message:
  0xC00D11B1 - Windows Media Player cannot play the file. This can occur when another program or operating system component encounters a problem but does not communicate the nature of the problem to the Player.
• Windows Media Player may abruptly close after the license for the content has been downloaded.

This issue occurs if the computer is using a Windows XP Display Driver Model (XDDM) graphics adapter driver.

To resolve this issue, you must install the most current version of a Windows Display Driver Model (WDDM) driver for the video card or for the integrated video device in the computer. To do this, follow these steps:

• Make sure that the copy of Windows Vista is a validated, genuine copy. Visit the Genuine Microsoft Software page, and then click Validate Windows:

• Make sure that the video device has the most current WDDM drivers.

For a list of video cards that contain a graphics processing unit (GPU) that supports WDDM, visit the following Microsoft Web site: Make sure that you are using the latest WDDM-capable driver for the video devices. For more information, contact the manufacturer of your video device.
