Unfortunately, after I close it after running, the interface goes away, but its process lingers. Every time I start and close it it leaves yet another phantom process running. Not only that, but those processes seem to be unkillable, even when the kill utilities are run as Administrator... AND they persist even after a reboot! I find no Autostart, listed Service or Task that would keep it going after a reboot. This is a real mystery to me This must be something peculiar to this Windows 10 desktop computer. On my Win10 and Win11 laptops it runs and quits normally. There's no sign on their user forum of anyone else having such a problem. Can anyone suggest how I could troubleshoot this? ========== An example - this process started yesterday and is still there today after the computer being shutdown for the night: C:\Users\xxx\Desktop>pslist64 -x musescore4 PsList v1.4 - Process information lister Process and thread information for xxx: Name Pid VM WS Priv Priv Pk Faults NonP Page MuseScore4 6596 4851208 192448 149652 384200 181593 50 783 Tid Pri Cswtch State User Time Kernel Time Elapsed Time 5460 8 8392793 Wait:DelayExec 0:00:00.000 0:00:00.062 44:12:22.952 When I try to kill it with PSKILL, Task Manager, or Process Explorer I get an Access Denied message: C:\Users\xxx\Desktop>pskill64 -t 6596 PsKill v1.16 - Terminates processes on local or remote systems Unable to kill process 6596: Access is denied. =====================
