I'm sorry, I misunderstood. I thought this post was asking from the perspective of "How can I tell if I'm enrolled in that secret thing we learned about that Intel has a secret backdoor to our computers" from the perspective of "I want to make sure it is off/I'm not enrolled".

I was suggesting, if the PC isn't connected to the Internet in this hypothetical case, why does the Intel backdoor matter? It wasn't clear to me the OP was trying to actually use the Intel Management Engine for legitimate purposes. I apologize.
