I want to set the value for the option "Stop task if runs longer than" in the windows schedule task Trigger tab using Powershell.

Already tried with /DU switch but it is not working.

Below is the screenshot for the same. Windows Task Schedule Trigger Settings

let me know in case of any further information is required.

@TobyU: I tried your suggestion as well but it is not setting up the required value. Below is the screenshot for your reference. enter image description here

Thank you in advance.

I'm using Windows 10 Pro and PowerShell 7 and the following works well for me.

Creating a new task:

# Creating a task with multiple triggers and different execution limits $taskName = "MyTask" $trigger1 = New-ScheduledTaskTrigger -Once -At "2021-05-10 12:00:00" $trigger1.ExecutionTimeLimit = "PT20M" $trigger2 = New-ScheduledTaskTrigger -Once -At "2021-05-13 17:30:30" $trigger2.ExecutionTimeLimit = "PT50M" $taskTriggers = @( $trigger1, $trigger2 ) $taskAction = New-ScheduledTaskAction -Execute "notepad.exe" Register-ScheduledTask -TaskName $taskName -Trigger $taskTriggers -Action $taskAction

For updating the trigger of an existing task the solution proposed by @TobyU worked well for me:

# Updating execution limits of a task that already exists $taskName = "MyTask" $task = Get-ScheduledTask -TaskName $taskName $task.Settings.ExecutionTimeLimit = "PT30S" # Global limit $task.Triggers[0].ExecutionTimeLimit = "PT10S" # Limit for trigger 1 $task.Triggers[1].ExecutionTimeLimit = "PT15S" # Limit for trigger 2 Set-ScheduledTask $task

However, you can also completely replace the old trigger with a new one:

# Completely replacing all triggers with new one of an already existing task $taskName = "MyTask" $trigger = New-ScheduledTaskTrigger -Once -At "2021-05-17 17:17:17" $trigger.ExecutionTimeLimit = "PT42M" Set-ScheduledTask -TaskName $taskName -Trigger $trigger

You can set it for the whole task at once:

$task = Get-ScheduledTask -TaskName "MyTask" $task.Settings.ExecutionTimeLimit = "PT3H" Set-ScheduledTask $task

Stops after 3 hours in the above example.

This is how you set it only for a specific trigger:

$task = Get-ScheduledTask -TaskName "MyTask" $task.Triggers[0].ExecutionTimeLimit = "PT3H" Set-ScheduledTask $task

Where Triggers[0] is the specific trigger you want to adjust since $task.Triggers returns an array with all the available trigger objects for the specific task.

Create Schedule Task Remotely

Invoke-Command -ComputerName Computername -Scriptblock { $action = New-ScheduledTaskAction -Execute 'C:\app.exe” ' $trigger = New-ScheduledTaskTrigger -Daily -At 10am -RandomDelay (New-TimeSpan - Minutes 480) $principal = New-ScheduledTaskPrincipal -GroupID "BUILTIN\Administrators" - RunLevel Highest Register-ScheduledTask -Action $action -Trigger $trigger -Principal $principal - TaskName "Schedule_task_name" -Description "Task Description" $Task = Get-ScheduledTask -TaskName "Schedule_task_name" $Task.Triggers[0].ExecutionTimeLimit= "PT30M" Set-ScheduledTask $Task }

Looks like your format for the ExecutionTimeLimit may need tweaking. In my case, I wanted the setting removed (ie the tickbox unticked). I couldn't figure this out, but using the following format for ExecutionTimeLimit did work, so I could set it to a far away value: d.hh:mm:ss, ie 1000 days:

$settings = New-ScheduledTaskSettingsSet -ExecutionTimeLimit 1000.00:00:00 Register-ScheduledTask -TaskName 'name' -Action $action -Trigger $trigger -Settings $settings
