For fetching Win32-Processes, there are several possibilities, e.g.

#!perl -w
use strict;
use Win32::OLE qw(in);

#Mode: Window Management Instrumentation (WMI)

# processproperties
my @properties = qw(Caption CreationClassName CreationDate CSCreationC

            WriteOperationCount WriteTransferCount);

# processmethods
my @methods = qw(Create Terminate GetOwner GetOwnerSid);

my $server = ''; # local machine

my $locatorObj = Win32::OLE->new('WbemScripting.SWbemLocator')
    or die ("Error in creating locator object: ".Win32::OLE->LastError

$locatorObj->{Security_}->{impersonationlevel} = 3;

my $serverObj = $locatorObj->ConnectServer($server, 'root\cimv2')
    or die ("Error in creating server object: ".Win32::OLE->LastError(
