Thanks too !!! Unbidden for finding this link to
google groups
and thank you James Dooley for this fix
To exit that app, run (Note that "/Close" is case sensitive):
"\Program Files\Windows Media Player\wmpnscfg.exe" /Close
To make it not run again, open the registry key
HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences\HME and set the
DWORD value DisableDiscovery to 2. If you had a UPnP Media Renderer or
control point on your local network, you'd also be able to disable it by
right-clicking on its taskbar icon (which only shows if it finds a UPnP
Media Renderer or control point) and choose "Disable Future Notifications".
As to why it starts running when you've disabled media sharing, that's a bug
in WMP 11 Beta2.
