The Microsoft Windows Media Technology Distribution Agreement for Windows Media Player 11 (view and download a sample here) allows you to distribute Windows Media Player 11.
Licensing Process: please review these steps.
The Microsoft Windows Media Rights Manager 10.1 Software Development Kit License Agreement (view and download a sample here) allows you to develop and operate software for Windows Server 2003 that packages (encrypts) content into Windows Media DRM and acts as a license server to generate and distribute DRM licenses for Windows Media DRM-packaged content.
Note: WMDRM10 has been superseded by PlayReady as the content protection technology from Microsoft. Any new development requiring content protection should implement PlayReady.
The License Agreement for Certificates for Windows Media Format 11 Software Development Kit (view and download a sample here) allows you to obtain and distribute DRM certificates in Windows applications, including the DRM Client Certificate, WMDM Transfer Certificate, DRM Encryption Certificate, and WMDM Service Provider Certificate, on a royalty-free basis. These DRM certificates allow your application to use the DRM components included in the Windows Media Format SDK.
The Microsoft Windows Media and HDCD – Logo License Agreement and its associated logos (for example, PlaysForSure and HDCD) are no longer available as of 2009.
Microsoft will continue to focus on our Windows brand and feels our partners will get the most benefit from a single program. The Windows hardware logo program is the only logo option now available for Windows Media compatible hardware. We encourage you to start following the Hardware Logo Program process to obtain an appropriate logo. For an explanation of how to use the Windows Media trademark and an overview of the logos associated with Windows Media, go to Windows Media Trademark Guidelines.
Although this porting kit has been retired, technical specifications for the Windows Media networking protocols are made available at no charge in the MSDN Open Specifications library. Rights to patents that cover those specifications are available separately. For more information, go to the Open Specifications website.
PDDRM was originally developed by Microsoft in 1999 as part of Windows Media Digital Rights Management (DRM) version 1. With the release of much more sophisticated and comprehensive content protection technologies from Microsoft (for example, PlayReady), PDDRM has become a legacy technology, and its source code and documentation are no longer available.
For information, see the Compliance and Robustness Rules for Windows Media DRM page.
You can add Windows Media DRM 10 to a product based on Windows CE so that it can acquire content and licenses directly from the Internet. To do so, submit the DRM Amendment to your Windows CE 5.0 License Agreement. This amendment is only available to those who have already licensed Windows CE. To obtain this amendment, contact the distributor from whom you licensed Windows CE, or contact your Microsoft account representative if you licensed Windows CE directly through Microsoft.
As of June 19, 2009, Microsoft has made changes to the way Windows Media DRM (WMDRM) for Devices is licensed. These changes provide device manufacturers with cost-effective technology for today's devices while facilitating future use of a richer set of DRM features and other improvements via use of the PlayReady code base.
