How to give extra privileges to the runner over the self-hosted Windows server?

It looks like the runner uses the nt authority\network service account to run PowerShell commands (checked using whoami within the workflow).

This isn’t useful when trying to deploy my app to my server. For example, I need to use schtasks.exe which gives ERROR: Access is denied.

Can I give extra privileges to the runner to avoid issues like this?

I found the easiest solution for my issue was to change the account the GitHub Actions service ran under.

I achieved this by using powershell "(Get-Service actions.runner.*).name" to find the name of the GitHub Actions service.

And then running sc config "NAME_OF_YOUR_SERVICE" obj= "NT AUTHORITY\SYSTEM" type= own to update it to run as the system.

@snankens you need to run the command with cmd and not powershell.
