Microsoft’s WMDM PMSP Service, aka Windows Media Device Manager Pre-Message Security Protocol Service. From our tests this service only appears in the Task List if you have done a Windows Update and updated Windows Media Player with the 26-Jun-2002 Security Update Q320920. This services enables Windows Media Player to support the SDMI protocol (Secure Digital Music Initiative) when copying CDs or packaging copyrighted downloaded music to SDMI compliant music players and storage devices.
Recommendation :
This process takes at least 1.2Mb of memory, yet at the time of writing, November 2002, most users do not use any of the SDMI features of Windows Media Player. Therefore, if you are such a user, we advise that you disable this process with Startup Manager under Windows 9x/ME, or set this service to manual in Windows 2000/XP/2003. You can always re-enable it if you start needing to use some of the SDMI features of Windows Media Player.
