PMS as a service

Hey mate, love your work on the service application. Works a treat.
I have a couple of questions you may be able to assist with.

I am looking at the updater application Updating Plex When Plex is Running as a Windows Service - Plexopedia

I was wanting to know, do you run this every time you want to update?
Is there any specific location it must be in?
Does it require admin tools?
Is it possible to just install updates from the web UI?
