Thanks for putting this together
I don't suppose you could make alist of the steps to properly change it to use a differant user than was used to install plex?
The info in post #4 should be sufficient.
When you install the service in the admin account, you give it the username you want to run the service in. All that is left is making sure that Plex Media Server does not run in the Admin Install Account whenever you do an install / upgrade / repair of Plex Media Server. So never leave 'Launch' ticked at the end of an install and remove the auto start registry key as stated in post #4
