You never kill the process, so it never dies.

use strict;
use warnings;

sub start {
    my $pid;

    {
        # We don't need to talk to the process,
        # So we don't need open3.

        # Close communication channels.
        local *STDIN;
        local *STDOUT;
        local *STDERR;

        # Launch child process.
        $pid = eval { system 1, @_ }; # 1 == P_NOWAIT
    }

    die("Can't spawn-NOWAIT: $!\n")
        if !$pid || $pid < 0;

    return $pid;
}


sub stop {
    my ($pid) = @_;
    kill(15, $pid) and waitpid($pid, 0);
}


# Arguments to the program must be passed in seperate function args
# For example,
#
#   my $tor_pid = start('C:\\Programme\\service.exe', 'arg1', 'arg2');
# 
# If you don't, you'll get the PID of the shell that's created
# to launch the program, and stop() won't work.

my $tor_pid = start('C:\\Programme\\service.exe');
print "tor started\n";  
sleep 3;
stop($tor_pid);
print "tor stopped\n";
