I’m running the 1.18.2.2029 version of the server on Windows, but this issue has been present for some time.
I’m running it under a local user, to ease permissions on networked file shares.
The “Plex Update Service” is set up to “Log on As” the “Local System” account. I can go into the service properties and change it to my local account, but it changes back after every update.
This adds additional manual steps with every server update.
Summary: When the Plex Update Service updates itself, it should log on as whatever user it’s been customized to.
