If program is running as administrator, add [Administrator] to the window title.

There is a wrapper function called IsUserAnAdmin() in the Windows API, but for some reason Microsoft recommends that you don't use it (http://msdn.microsoft.com/en-us/library/bb776463%28VS.85%29.aspx).

The method to determine if a user is admin is taken from http://msdn.microsoft.com/en-us/library/aa376389%28v=vs.85%29.aspx
