Here a function to list all the processes running on a machine. It uses Win32::Perflib.
The function returns a pid-indexed hash with all the tasks running on a Win32 machine, as listed in the task manager.
You'll notice, that the function takes the machine you want to monitor as an argument: it is possible to get the task list of a remote machine.
It can be used as the first part of a program to fully remote control a Win32 machine (you will probably need to use Win32::Process to kill programs, and implement some sort of client server protocol also, a very tiny job for a Perl Monk :-)
sub get_remote_process_list {
    
my $server = $_[0];
    
my %rtasks;
my %counter;
    
Win32::PerfLib::GetCounterNames($server, \%counter);
my %r_counter = map { $counter{$_} => $_ } keys %counter;
# retrieve the id for process object
my $process_obj = $r_counter{Process};
# retrieve the id for the process ID counter
my $process_id = $r_counter{'ID Process'};
    
# create connection to $server
my $perflib = new Win32::PerfLib($server);
my $proc_ref = {};
# get the performance data for the process object
$perflib->GetObjectList($process_obj, $proc_ref);
$perflib->Close();
my $instance_ref = $proc_ref->{Objects}->{$process_obj}->{Instances};
foreach my $p (sort keys %{$instance_ref})
{
    my $counter_ref = $instance_ref->{$p}->{Counters};
    foreach my $i (keys %{$counter_ref})
    {
        if($counter_ref->{$i}->{CounterNameTitleIndex} == $process_id)
        {
            $rtasks{$counter_ref->{$i}->{Counter}} = $instance_ref->{$
+p}->{Name};
        }
    }
}
  return %rtasks;
}
