Check out Win32 Perl Scripting: The Administrator's Handbook by Roth. There are loads of Admin script in there.

Also check his script repository for more admin scripts.

Update: I include a simple script that takes a command line parameter and searches for that in the process list and kills all instances found.. to test simply launch many notepad.exe processes.. then run the following script I.e. pkill.pl notepad

#! /usr/bin/perl

use strict;
use warnings;

use Win32;
use Win32::API;
use Win32::Process;
use Win32::OLE qw( in );    #Identify the Process that have been left 
+to kill
use Win32::OLE::Variant;    #Identify the Process that have been left 
+to kill

my $app = $ARGV[0];

if ($app) {
    my $rc     = 1;
    my $srv = "\\\\" . $ENV{'COMPUTERNAME'};

    my $CLASS = "winmgmts:{impersonationLevel=impersonate}$srv\\Root\\
+cimv2";
    my $WMI = Win32::OLE->GetObject( $CLASS ) || die;
    foreach my $Proc ( sort {lc $a->{Name} cmp lc $b->{Name}} in( $WMI
+->InstancesOf( "Win32_Process" ) ) )
    {

        my $regex1 = "($app)";

        if ($Proc->{Name} =~ /$regex1/i) {
            print "INFORMATION - About to kill $Proc->{ProcessID} for 
+$app\n";
            unless (Win32::Process::KillProcess($Proc->{ProcessID}, 0)
+) {
                print "Could not kill $Proc->{ProcessID} for $app\n";
            }
        }
    }
}
else {
    print "$0 <app name>\n";
    print "<app name> = name and extension or (part therof I.e. note f
+or notepad) of process to kill\n";
