SYMPTOMS
After you set the sound scheme to &quot;No Sounds,&quot; the system may search for the &quot;Close.wav&quot; file on Application Close Events. If you have any network shares mapped as a local system drive or have a network share path in the system &quot;PATH,&quot; and you are running programs or open windows from these network shares, on system shut down, the system closes these open programs or windows. When the system searches for the &quot;Close.wav&quot; file on a network share when you shut down your computer, you may receive a STOP 0x50 error message.



CAUSE
This problem can occur because when you set the sound scheme to &quot;No Sounds,&quot; the system does not handle this setting correctly. When the system searches for the Close.wav file on network shares when you shut down your computer, a code bug in the Mup.sys file can cause a STOP 0x50 error messag.
