使用提升的權限調用自定義操作，但不以LocalSystem調用

我想從自定義操作創建計劃任務。我需要提升權限才能創建它。我正在使用Task Scheduler Managed Wrapper。使用提升的權限調用自定義操作，但不以LocalSystem調用

using (TaskDefinition taskDefinition = TaskService.Instance.NewTask()) 
    { 
     taskDefinition.RegistrationInfo.Date = DateTime.Now; 
     taskDefinition.RegistrationInfo.Description = "..."; 
     taskDefinition.Principal.RunLevel = TaskRunLevel.Highest; // Scheduled Task with elevated privileges 

     DailyTrigger trigger = new DailyTrigger(); 
     try 
     { 
      trigger.StartBoundary = new DateTime(DateTime.Today.Ticks) 
       .AddHours(20); 
      trigger.ExecutionTimeLimit = TimeSpan.FromSeconds(30); 
      trigger.DaysInterval = 2; 
     } 
     catch 
     { 
      trigger.Dispose(); 
      throw; 
     } 

     taskDefinition.Triggers.Add(trigger); 
     taskDefinition.Actions.Add(Path.Combine(session.CustomActionData.Keys.Single(), "Updater.exe")); 

     TaskService.Instance.RootFolder.RegisterTaskDefinition(TaskName, taskDefinition); 
    }

根據How to run custom executable with elevated privileges?我必須使用
