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.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.
