Start in salt/modules/win_task.py at create_task_from_xml around lines 649 and 704, then reproduce the reported Windows command with an XML file. Verify how xml_path is handled and how the hexadecimal error code is matched; done means the XML task creation returns True and the reported error is displayed correctly.
