Schedule running executable using powershell - powershell

Question

I need to write a script, which will create task scheduler job, which at pc startup will run executable. In short, script will be something like this:
$trigger = New-JobTrigger -AtStartup -RandomDelay 00:00:10
Register-ScheduledJob -Trigger $trigger -Name FileJob -ScriptBlock {$args[0]}
But it doesn't work. What's wrong?

Answer 1

I use the following Powershell snippet to create Windows Scheduled Tasks.
$action = New-ScheduledTaskAction -Execute 'application.exe' -Argument '-NoProfile -WindowStyle Hidden'
$trigger = New-ScheduledTaskTrigger -AtStartup -RandomDelay 00:00:10
Register-ScheduledTask -Action $action -Trigger $trigger -TaskName "FileJob" -Description "FileJob"

Answer 2

This is what I use to create my task:
#The first command uses the New-ScheduledTaskAction cmdlet to assign the action variable $A to the executable file tskmgr.exe
$A = New-ScheduledTaskAction -Execute "C:\WINDOWS\SysWOW64\WindowsPowerShell\v1.0\powershell.exe" -file "C:\directory\powershell.ps1"
#The second command uses the New-ScheduledTaskTrigger cmdlet to assign the trigger variable $T to the value AtLogon
$T = New-ScheduledTaskTrigger -weekly -DaysOfWeek Saturday -At 7am
#The third command uses the New-ScheduledTaskSettingsSet cmdlet to assign the settings variable $S to a task settings object
$S = New-ScheduledTaskSettingsSet -AllowStartIfOnBatteries -DontStopIfGoingOnBatteries -DontStopOnIdleEnd -ExecutionTimeLimit 1:00:00 -MultipleInstances 2
#The fourth command assigns the principal variable to the New-ScheduledTaskPrincipal of the scheduled task, Domain\Username
$P = New-ScheduledTaskPrincipal -UserId domain\gMSAaccount$ -LogonType Password -RunLevel Highest
#The fifth command sets the description varible to $D for the task definition
$D = "Insert your description here"
#Registers the new scheduled task and defines it by using the $D variable
Register-ScheduledTask Name_of_Task -Action $A -Trigger $T -Settings $S -Principal $P -Description $D<p>
I found that using gMSA accounts are the best in an active directory environment. Implement gMSA The requirement is that in order to use gMSA, you must create your task with a powershell script or schtask.exe.
