We should use different principals for the scheduled task and running the game.

The scheduled task needs write access over steamcmd for autoupdate and allow login as batch job.
This could run under the current user's principal unless another account is specified (it should not be LocalService).
It also needs:

• Read access to the server configuration file, pid files, and the STEAM_USERNAME environment variable
• Write access to workshop content, master, config and transcript logs

The game should run as LocalService with as few privileges as possible. It needs:

• Read access to workshop content, master, config
• Write acess to pid files and profile directory

As a consequence, pid fils should not go in the config directory, and transcripts should not go in the profile path.
