you just gived me a reason to reboot into Windows XP :)

i found 2 ways of getting the PID of a process on a Windows XP system:

1. use the command tasklist (installed by Windows in %WINDIR%\system32) to get a table with details of the running processes on your system that you could easly parse

2. use Win32::Process::Info from CPAN to get more details

   #!perl
   
   use strict;
   use warnings;
   
   use Data::Dumper;
   use Win32::Process::Info;
   
   my $procs = Win32::Process::Info->new();
   print Dumper $procs->GetProcInfo();
