one end user maybe, but many other "users" too. SYSTEM, NETWORK SERVICE, LOCAL SERVICE are but a few others. Maybe this will help, i use it to identify who runs my code from a console 

use Win32;
my $user = Win32::LoginName();

If you can put your process into sleep for a bit and can identify it from this list this may help 
use strict;
use warnings; 
use DBI;
use DBD::WMI qw/connect prepare execute fetchrow/;
use Win32::OLE qw/in/;
