Spotify first killed itself but "something of it" kept lingering which was detectable as a task with PID 8664 and judging from the fact that RAM usage kept changing from time to time - it "did something".
Now first of all this process kept me from listening to music because Spotify refused to restart due to this instance hanging around.
So I tried to get rid of this process. But neither task manager nor the taskkill command (as Admin of course) succeeded in doing so.
taskkill at least gave me a "reason" which I will translate here.
>taskkill /pid 8664 /f >taskkill /im spotify.exe /f
ERROR: The process "spotify.exe" with PID 8664 could not be terminated. Reason: There is currently no instance executed by this task.
I would like to know what that means and whether there is another option of how to terminate such a process.
