Win32::Process::Info The following lists all processes, but you can pass a list of pids to only get info on those ids.

#! perl -slw
use strict;
use Win32::Process::Info;

my @fields = qw[
    ProcessId
    Name
    ExecutablePath
    UserModeTime
    KernelModeTime
    MaximumWorkingSetSize
    MinimumWorkingSetSize
];
my $i = new Win32::Process::Info;

printf "%10.10s %-22.22s %-40.40s %12.12s %14.14s %7.7s %7.7s\n", @fie
+lds;
printf "%10.10s %-22.22s %-40.40s %12.12s %14.14s %7.7s %7.7s\n",
    map{ defined() ? $_ : 'n/a' } @{ $_ }{ @fields }
    for $i->GetProcInfo();

Caution: The Max/MinWorkingSet (memory) sizes coming up on my machine are very suspect?

The script below used to produce good numbers on my old NT box, so it's probably something broken with my installation.
