To stop go into services, find "Windows Media Player Network sharing Service", right-click = Properties; set to manual start. It seems to start automatically after WMP has been used. Maybe only real solution is to get rid of WMP, I dunno.

I have Mezzmo which spreads the sharing of the media files to others in the network. i have Windows 7 Ultimate and it does put a clutch on my processor when it starts runnning. So do the Mezzmo Media server it does put a heavy load on my AMD 8 core processor

I had a virus locate in random folders all secured and undeletable i used "unlocker" and when I went into the folder there was hidden folders (That I couldn't see when I chose to show hidden files) Called "VVVV" "WWWW" "XXXX" "YYYYY" "ZZZZ" So i unlocked and deleted them. I am going to do a full system scan in safemode now :)

Best practices for resolving wmpnetwk issues

A clean and tidy computer is the key requirement for avoiding problems with wmpnetwk. 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 doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
