Can't kill/restart process on server, sometimes 2 instances of PMS
AppData/Local/Plex Media Server has read rights using install account and one used for services
Are you having different user for install from one you run PMS Service under?
If you are, then the auto start would be having in the install account leading to 2 instances.
See my post #4
The registry setting is for the user account and would be different depending on which session loads up regedit
