COM objects are used to protect Windows Media files and issue licenses, enabling you to integrate these processes into your current business model. Packaging Windows Media files and issuing licenses can be performed on a larger scale. More information, including custom fields, can be added to the content headers of Windows Media files, enabling you to easily track transactions in a distributed retail model.
Rights are now more robust and flexible.
For example, you can now allow counted operations, and specify dates on which to begin and end license validity. Consumers can back up and restore licenses, which is a right you can set in licenses. The License Management Service, run by Microsoft, also enforces business rules to prevent abuse of content. Windows Media License Service version 1 has been updated to enable you to extract certain fields from the registry rather than from a database. These changes make it possible to run both version 1 and version 7 of Windows Media License Service on one computer.
