This is pretty harmless and a part of Microsoft's Windows Media Player. However it occupies space in your memory and doesn't actually serve you the consumer in any way... Disabling it won't harm your system in anyway and will free up some RAM. So yes, disable it!

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.
