I can follow the above instructions until I get to number 6. 

QUESTIONS:
What is the "friendly name" referred to in this action and/or how do I find out what it is?
What is the "AppGUID identifier?

I am somewhat embarrassed by not knowing what my user's account name is in instruction 10.

QUESTION:
Where can I locate my user's account name on my computer?

I think I am good to go on all of the other instructions.  

I welcome any help/guidance you send my way that relates to fixing this error.

((P.S. - My computer is owned, operated, and administered by one user - me.  I don't have to select administrator or user at start up on this computer.  The only connection associated with this computer is to a router that is connected to my  ISP.)
