I do something like this to fork off another process on Win32. 

use Win32::Process;

$bInherit = 0;
$Dir = "c:\\";
$Flag = CREATE_SUSPENDED | CREATE_NEW_CONSOLE | HIGH_PRIORITY_CLASS ;
if (Win32::Process::Create( $Process, $App, $Cmd, 
    $bInherit, $Flag, $Dir ) ) {
    $Pid = $Process->GetProcessID();
    print "\n\tnew process created with PID $Pid";
    while (1 < $Process->Resume() ) { }
    $Result = $Process->Wait($Timeout * 1000);
    if (! $Result) {
        print "$tmp did not end in $Timeout sec, killed";
        $Process->Kill(0);
    }
    else {
        # process ran ok, give message
    }
}
else {
    print "\nunable to create the new process.\n";
    $tmp = Win32::FormatMessage(Win32::GetLastError() ) ;
    print "\n $0 Error: $tmp\n";
}
