I have a program, Musescore (a music notation software) that was recently 
updated from version 3 to 4, with many nice improvements. 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

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.
