Closed Issue: Use a Group Managed service account to run a schedule task and make it "Run whether user is logged on or not"? [12362]

These two ways are not working, here is my test code, I test it on windows server 2012R2:
```
using System;
using System.Runtime.InteropServices;
using Microsoft.Win32.TaskScheduler;

namespace WrapperDemo
{
internal static class Program
{
public static void Main(string[] args)
{
try
{
var action = new ExecAction(@"C:\PowerSlim\test.cmd");
var trigger = new DailyTrigger(1);
trigger.StartBoundary = DateTime.Today.AddHours(20);
TaskService.Instance.AddTask("msaTask", trigger, action, @"er\zz$", "", TaskLogonType.Password);
}
catch (COMException exception)
{
Console.WriteLine(exception.ToString());
}

}
}
}

```
I got exception like following on the console output:

System.Runtime.InteropServices.COMException (0x8007052E): The username or password is incorrect. (Exception from HRESULT: 0x8007052E)
