Microsoft acknowledged an issue impacting customers running Windows 7 RTM and Windows 7 SP1, with copyright protected content failing to play on their computers. According to Microsoft "On a Windows 7 PC, you cannot play a media file. Media file is Windows Media Digital Rights Management (DRM) protected or Zune DRM protected. Additionally, you cannot purchase or play new Windows Media DRM protected media files and Zune DRM protected media files on this computer."

"This issue occurs because Windows 7 is preinstalled on a new computer by using image-based Windows deployment technology. Windows Media DRM and Zune DRM systems are affected by this type of Windows 7 installation," the Redmond company explained in KB976590.

To resolve this issue, you must check the functionality of Windows Media DRM and Zune DRM. If Windows Media DRM and Zune DRM do not function, use the ResetDRM tool to reset DRM systems. To do this, follow these steps:

  1. Download a sample media file and save it to your computer. Open the downloaded file to play the media.
  2. If you receive an error message about media usage rights when you try to play the media file, you must use the ResetDRM tool.
  3. To use the ResetDRM tool, follow these steps:
    • Download the ResetDRM tool and save it to your desktop.
    • Right-click ResetDRM.exe, and then click Run as administrator to reset the Windows Media DRM and Zune DRM systems.
    • Replay the downloaded media file that was used in step 1 to re-test Windows Media DRM and Zune DRM.
