As the name would imply, this software is a service wrapper for Plex Media Server.
You can use it to run PMS on a Windows computer without having to be logged in. Just install it, set the user it should run as, and you're all set.
Optionally, you can use PlexService to configure remote drive mappings for your media, as well as auxiliary applications to run when Plex is running.

Simply download the latest release, run the installer, and enter the user information when prompted.
You can also silently install the package using the following syntax:
msiexec.exe /i c:\PlexServiceInstaller.msi /QN SERVICE_USERNAME="MyUsername" SERVICE_PASSWORD="MyPassword"
NOTE: You must run the install command as administrator if executing silently, as the application can't prompt for elevation. Installation will fail if you don't run your script/command prompt as admin.
You should be able to upgrade PlexService in-place. In rare occurrences, you may not be able to properly update or uninstall PlexService.
If that happens, see below for steps to manually remove it for a clean installation.
To completely remove the PlexService application, do the following:
sc stop PlexService
taskkill /IM PlexService.exe /F
sc delete PlexService
del /S C:\progra~2\PlexService\
del /S "C:\users\<PMSSERVICEUSERNAME>\AppData\Local\Plex Service\"
