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.

Best practices for resolving WMPNSCFG issues

A clean and tidy computer is the key requirement for avoiding problems with WMPNSCFG. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the WMPNSCFG.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
