You can enumerate tasks from the Root folder.
A test =>

' Add reference to : TaskScheduler 1.1 Type Library  
' Add : Imports TaskScheduler  

(Manifest with requireAdministrator to get all tasks)

        Dim ts As ITaskService = New TaskScheduler.TaskScheduler()  
        Try  
            ts.Connect(Nothing, Nothing, Nothing, Nothing)  
        Catch ex As Exception  
            System.Windows.Forms.MessageBox.Show("Error : " & ex.Message.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.[Error])  
            Return  
        End Try  
        Dim tf As ITaskFolder = ts.GetFolder("")  
        If (tf IsNot Nothing) Then  
            Dim tc As IRegisteredTaskCollection = tf.GetTasks(TaskScheduler._TASK_ENUM_FLAGS.TASK_ENUM_HIDDEN)  
            If (tc IsNot Nothing) Then  
                Dim nCount = tc.Count  
                For n = 1 To nCount  
                    Dim task As IRegisteredTask = tc.Item(n)  
                    Console.WriteLine("Task n°{0} = {1}", n, task.Name)  
                Next  
            End If  
        End If
