Check Disabled state after Disable-ScheduledTask status on Running Task

[RedModSK]

Hello to all, i seek your wisdom!
I am trying to automate the following steps performed manually:
- Disable a running scheduled task, but keeping it running.
- Do actions that stop the task process.
- Do additional actions.
- Enable scheduled task and run it.

I can do all the steps in PowerShell, but the issue i have is that when i use:
Disable-ScheduledTask -TaskName 'TaskName' -TaskPath '\TaskPath\'
while the task remains running, i am not able to get the Disabled state with:
Get-ScheduledTask -TaskName 'TaskName' -TaskPath '\TaskPath\'
In the taskschd.msc ui i can see the option to enable the task, so i see hat is is disabled
But i need to confirm the Disabled state from PowerShell.
I am not able to find anything in task cim properties either.

I hope one of you knows the solution to my dilema.

There's two points of interest within the scheduled task WMI class:

1. The State property, which tells you the current execution status
2. The Triggers property, which is an array of further WMI MSFT_TaskLogonTrigger objects.

What you are checking for in your final stage is State when you should be checking the Triggers array.

Here is a simple example script that demonstrates the difference between State and Triggers, where each object within the Triggers array contains a property named Enabled, which indicates if the trigger is enabled or disabled, which is what your final question is alluding to.

Get-ScheduledTask -TaskName "SystemSoundsService" |
    ForEach-Object {
        $Task = $_;

        for ($index = 0; $index -lt $Task.Triggers.Length; $index++) {
            [PSCustomObject] @{
                Task = "$($Task.TaskPath)$($Task.TaskName)";
                State = $Task.State;
                Trigger = $index;
                TriggerEnabled = $Task.Triggers[$index].Enabled;
            }
        }
    }

Hello @LainRobertson
thank you for your fast reply. I think i understand your State and Trigger explanation. However, the trigger comes back the same enabled : True, when the task is enabled or disabled. 

Looking at your script i am a bit confused. You are running a foreach-object, but there seems to be only one state and one trigger property for a service, as far as i can see. For example:

$task = Get-ScheduledTask -TaskName "RtkAudUService64_BG" -TaskPath \
$task | Get-Member

   TypeName: Microsoft.Management.Infrastructure.CimInstance#Root/Microsoft/Windows/TaskScheduler/MSFT_ScheduledTask

State                     ScriptProperty System.Object State {get=[Microsoft.PowerShell.Cmdletization.GeneratedTypes.ScheduledTask.StateEnum]($this.PSBase.CimInstanceProperti

$task.Triggers

Enabled            : True

ExecutionTimeLimit :
Id                 :

StartBoundary      :
Delay              : PT30S
UserId             :
PSComputerName     :

Or do you mean that every object has a corresponding trigger in WMI MSFT_TaskLogonTrigger object?
Sorry for the confusion :(

i was poking around the system where could i see some additional info and i found this, when running schtasks /query:

PS C:\Windows\System32> schtasks /query /TN "\RtkAudUService64_BG" /XML

      <Arguments>-background</Arguments>
    </Exec>
  </Actions>
</Task>

The <Enabled>false</Enabled> line in Settings, is visible only when the task is disabled.

I would rather however use the PowerShell commandlets, to get the values.

Hi,

Sorry, try this instead, which checks the Settings.Enabled property:

Get-ScheduledTask -TaskName "SystemSoundsService" |
    ForEach-Object {
        [PSCustomObject] @{
            Task = "$($_.TaskPath)$($_.TaskName)";
            State = $_.State;
            Enabled = $_.Settings.Enabled;
        }
}

The principle is the same as for Triggers, it's just that the Settings.Enabled describes the job as a whole rather than Triggers.Enabled that returns the status of each trigger in the Triggers array.

Thats it, thank you mate!
I am surprised and a bit ashamed, that i did not see it when i was going through the properties.
