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 -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
