Configuration Persistence

None of the write-enabled properties described in this documentation are saved by the Windows Media SDK. Each application that uses the SDK must provide its own persistence procedures as needed and invoke the appropriate set method upon each instance of the SDK. In this way, configuration changes made by one application do not affect another application. For example, changing the buffering time in one player does not affect another player.

The one exception to this rule is for the credentials information. If the application indicates, in its return from the AcquireCredentials call, that the user ID and password information must be persisted, the SDK saves this information.
