This is funny. UAC creates another session on prompt but it's
unlikely the call is documented because powershell "remoting" sessions
also run in session 0. I think this is funny because MSFT made such a
big thing of the work they did in Vista to move processes out of
session 0 from the console.
For the admin rights, I think it's low hanging fruit just to change
the default owner to system but whatever
