Powershell - Create Scheduled Task to run as local system / service

Question

Can anyone tell me how to create a scheduled task using powershell that runs as the local system or local service?

Everything works great except the call to ITaskFolder.

Answer 1

This code snippet will use the PowerShellPack's Task Scheduler module to schedule a task to run as SYSTEM immediately:

New-Task |
    ForEach-Object {
        $_.Principal.Id = "NTAuthority\SYSTEM"
        $_.Principal.RunLevel = 1
        $_
    } |
    Add-TaskAction -Script {
        "SystemTask" > C:\myTest.txt
    } |
    Add-TaskTrigger -OnRegistration |
    Register-ScheduledTask SystemTask
