Although Windows themselves ADMIT there are problems with this driver (see website link below). It is ONLY a problem IF you are using older WMP (or updated versions of earlier versions ) to rip Copy Protected discs (I am sure NONE of us does that....ROFL) , there are many FREE programs that does this better and faster... (mine are built into my Soundblaster Cards , = SoundBlaster:- Live 5.1 ,Live, Audigy, Audigy 2 , X-Fi..) - Realplayer actually asks if you want to copy a DRM (Digital Rights Management) protected disk. as for MP3 downloads they have removed the Copy Protection , as they had too many complaints , that people could ONLY listen to Downloads on the PC and not copy them to disk to listen to elsewhere. Anyway it can be found in 2 places on your PC:- c:\windows\system32\mspmspsv.exe + C:\WINDOWS\Prefetch\ Am sat on the fence on this one , as it doesn't cause me problems...!!

Hd two pc's within a week of each other start freezing up. One was from this MsPMSPSv.exe process. disabled it and it stopped freezing after boot. the second maching did not have this file but found that i was freezing the same way right after booting up becuase of a similar WMplayer process called Windows Media Player Network Sharing service and the executable namesed WMPNetwk.exe. Disabled this process from starting on the 2nd pc and all is well with no freezing up. Anyne know if U uninstall MS update KB917734 WMP is for just the 1st one or will it uninstall other needed security patches

mspmspsv.exe Media Player Very very very commonly taken over by spyware / malware
In researching problems with ActiveSync not starting up automatically, I checked running processes. After reading this blog I disabled MSPMSPSV.exe and my ActiveSync suddenly initiated and synchronized successfully. Hmmmm....
Spyware! When I deleted it from the registry in regedit it came back again. And when I stopped and disabled it in 'Computer Management' I got this new spyware: CmdLineExt02.dll
mspmspsv.exe is a process which normally comes with a specific update of Windows Media player. It allows for the SDMI protocol (Secure Digital Music Initiative) to be used during dealing with music media. This is a non-essential process. Disabling or enabling it is down to user preference.

Best practices for resolving MsPMSPSv issues

A clean and tidy computer is the key requirement for avoiding problems with MsPMSPSv. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command.
