WMDM PMSP Service / Portable Media Serial Number

The service supports the Secure Digital Music Initiative(SDMI) and enables the WMDM (Windows Media Device Manager) to retrieve the serial number from portable music devices using Pre-Message Security Protocol(PMSP), so media content can be copied securely to the device.

If not being able to extract the serial number from the device (If this service is disabled or the device doesn't support it), then copyrighted music will not be allowed to be transferred to the device.
