Yes. It's not there (it disappears when I close the terminal window, as expected).
I also downloaded
process explorer and tried to search for processes under that name, or any other meaningful name I could think of, cannot find anything .. I also searched on how to list all running processes via powershell and sort them by datetime for example (show most recent on top so i don't get lost), again I can see the process (name, pid, everything) when the terminal window is open, but when i close it there seems to be no process kept running that could somehow explain 'locking' test3.exe ...
