I had no problems from it either at first. Just recently I've noticed CTD problems and been trying to eliminate causes. So far no more CTD discos since I deleted the file references. I dont think it hurts WMP 10 to remove the file, this is not a real driver, its a system integration manager. And your right, I really dont think they are using this much yet. Some of the complaints I saw on the internet though have people complaining that the process will seemingly randomly try to connect to the internet, hogging resources and messing up your internet connection. Perhaps its related to an autoupdater for the WMP? I dont know. I cant even swear it was the cause of my problems, but so far all is well even in heavy traffic areas and big bog down spots with lots of graphics and lots of other planes flying around.
