How to stop Vista 64 command line defrag?

I started "defrag -v -w" from the command line  and I think it's still running because I don't have a command line prompt and the hard disk light is still flashing quickly (and somewhat randomly).  Does anyone know how to stop the command line defrag process without corrupting anything?


The <esc> key does nothing and the Task Manager shows that defrag is running.


ctrl-c should stop it.
