Laravel 5.1 Task Scheduling on Windows

I'm trying to get Laravel 5.1 Task Scheduling working on IIS. When I run a batch file using Windows task manager it will run the task one time only. How can I get ->everyMinute() to work?

Windows batch file:

cd c:\inetpub\myapp
c:\PROGRA~2\PHP\php.exe artisan schedule:run 1>> NUL 2>&1

The kernel:

class Kernel extends ConsoleKernel
{
    protected $commands = [

        \App\Console\Commands\MyCommand::class,

    ];

    protected function schedule(Schedule $schedule)
    {
        $schedule->command('test')->everyMinute();
    }
}

The command:

public function handle()
    {
        log::info('test');
    }
