Engineer is a bad word for this. She is simply a MCP (Microsoft Certified Professional). Meaning she passed two exams on Windows XP (most likely). With questions reguarding TCP/IP, Remote Desktop, and Automated installs. She is far from an MCSE. And very very far from a computer engineer. On the other hand, being a 9 year old female, and knowing as much about Windows XP as she does is fairly impressive. Though there is the possibility she used 'brain dumps'. In which case you can pass any of these certification exams from Microsoft through Cisco, to Red Hat if you have a good memory.
I myself am an MCSE, and don't think we should be called engineers. Engineers is a term used far too much.
