I have been using the Powershell Scheduled Task Cmdlets to create a scheduled task on our servers.
How do I elect to 'Run whether a user is logged in or not using this API?
I've created action
, trigger
, principal
and settings
objects, and passed them to Register-ScheduledTask
, as below:
$action = New-ScheduledTaskAction -Execute foo.exe -Argument "bar baz"
$trigger = New-ScheduledTaskTrigger -Once -At $startTime -RepetitionInterval (New-TimeSpan -Minutes 1) -RepetitionDuration ([Timespan]::MaxValue)
$principal = New-ScheduledTaskPrincipal -UserId "$($env:USERDOMAIN)\$($env:USERNAME)" -LogonType ServiceAccount
$settings = New-ScheduledTaskSettingsSet -MultipleInstances Parallel
Register-ScheduledTask -TaskName $taskName -TaskPath "\my\path" -Action $action -Trigger $trigger -Settings $settings -Principal $principal
When I create a scheduled task like this, it defaults to 'Run only when the user is logged on.
This question shows how to do so using COM objects, and this one using schtasks.exe, but how do I do it using the *-ScheduledTask*
cmdlets?

I do not like or approve of the currently highest rated answer as then you have to know your credentials into a script to do this and can't do this from something like Packer or some other system/configuration automation. There is a better/proper way to do this which Aeyoun mentioned but didn't go into details about which is to properly set the principal to run as the system user.
