[wix-users] execution context for an All-Users install

[Alan Sinclair]

During an interactive All-Users install we know the process is elevated so
that it can install to %ProgramFiles% but what user context is it running
under? SYSTEM or the current user that initiated the installer?

 During an automated install (pushed out as a group policy object) what
user context are we running under, is it SYSTEM?

thanks
