New Post: how to use a Group Managed service account to run a schedule task and make it "Run whether user is logged on or not"?

Hi dahall, thinks for your reply. I use the following Powershell commands to create a schedule task with GMSA on a windows server 2012R2 machine:

$action = New-ScheduledTaskAction  "C:\PowerSlim\test.cmd"
$trigger = New-ScheduledTaskTrigger -At 20:43 -Daily
$principal = New-ScheduledTaskPrincipal -UserID er\zz$ -LogonType Password
Register-ScheduledTask msaTask –Action $action –Trigger $trigger –Principal $principal

then the xml of "msaTask" is like below:

<?xml version="1.0" encoding="UTF-16"?>
<Task version="1.3" xmlns="http://schemas.microsoft.com/windows/2004/02/mit/task">
