[issue30082] hide command prompt when using subprocess.Popen with shell=False on Windows

I would like to pick up work on this (have started at link below), however I would like some help:

For testing purposes, could someone please provide a minimum working example of using subprocess that causes a command prompt to pop up?

I have not been able to reproduce it (using Python 3.7), though I vaguely remember encountering it in the past.
