Powershell run job at startup with admin rights using ScheduledJob

Question

To ease some of my work I have created a powershell script which needs to :

1. Run at startup.
2. Run with admin rights as it has to write in c:\\program f

Answer 1

This is code that is already in production that I use. If it does not work for you, you must have something else going on with your system.

function Invoke-PrepareScheduledTask
{
    $taskName = "UCM_MSSQL"
    $task = Get-ScheduledTask -TaskName $taskName -ErrorAction SilentlyContinue
    if ($task -ne $null)
    {
        Unregister-ScheduledTask -TaskName $taskName -Confirm:$false 
    }

    # TODO: EDIT THIS STUFF AS NEEDED...
    $action = New-ScheduledTaskAction -Execute 'powershell.exe' -Argument '-File "C:\Invoke-MYSCRIPT.ps1"'
    $trigger = New-ScheduledTaskTrigger -AtStartup -RandomDelay 00:00:30
    $settings = New-ScheduledTaskSettingsSet -Compatibility Win8

    $principal = New-ScheduledTaskPrincipal -UserId SYSTEM -LogonType ServiceAccount -RunLevel Highest

    $definition = New-ScheduledTask -Action $action -Principal $principal -Trigger $trigger -Settings $settings -Description "Run $($taskName) at startup"

    Register-ScheduledTask -TaskName $taskName -InputObject $definition

    $task = Get-ScheduledTask -TaskName $taskName -ErrorAction SilentlyContinue

    # TODO: LOG AS NEEDED...
    if ($task -ne $null)
    {
        Write-Output "Created scheduled task: '$($task.ToString())'."
    }
    else
    {
        Write-Output "Created scheduled task: FAILED."
    }
}

If it works, it's not a script problem. Assign it to the SYSTEM account or make a separate service account instead of the Gagan account shown. Make sure that service account has "Permission to run as batch job" in your local security policy.

Answer 3

Please check the checkbox for "Run with highest privileges" for the task in the task scheduler and try again. Currently in the screenshot above it is unchecked.
