I have a local user on my Windows 2012 machine called "Master". The description of this user is "Built-in account for administering the computer/domain". I haven't found any information about this user online. Is this user there by default or is it just local to our system?
I am taking over this environment from others who have come before me. Most of the other machines I work on are Windows 2003 Server, or Windows 2008, or what have you.
