New Post: why scheduled task do not run when time is reached

        {
            // Create a new task definition and assign properties
            TaskDefinition td = ts.NewTask();
            td.RegistrationInfo.Description = "Does something";
            td.Principal.LogonType = TaskLogonType.InteractiveToken;

            TimeTrigger tTrigger = new TimeTrigger();
            tTrigger.StartBoundary = new DateTime(DateTime.Today.Year, 8, 15, 10, 42, 0);

            // Add a trigger that will fire every week on Friday
            td.Triggers.Add(tTrigger);

            // Add an action that will launch Notepad whenever the trigger fires
            td.Actions.Add(new ExecAction("notepad.exe", "c:\\test.log", null));

            // Register the task in the root folder
            const string taskName = "Test";
            ts.RootFolder.RegisterTaskDefinition(taskName, td);
        }
