It was running on my vista home basic, although i stopped it from msconfig. The problem was the file sharing mentioned before, was on. Couldn't stop sharing because window$ firewall was already stopped, so i had to switch firewall on, file sharing off, then firewall off. Now it's gone from the running processes.
I disabled the service and it still starts up. So then I right clicked on the service and opened up the properties I clicked the the logon tab and logged in as networkservices. the hardware service for the undocked p[rofile was enabled so I disabled it and rebooted. Hope this helps.
It's for Windows Media Player, no reason to have it start on OS boot though.
