The new subprocess module in Python 2.4 (also available for 2.2 and 2.3 at http://effbot.org/downloads/#subprocess) allows access to the handle of any newly created subprocess. You can use this handle to terminate subprocesses using either ctypes or the pywin32 extensions.

You can use either pywin32 or ctypes to call the Windows TerminateProcess API. Just pick one - there is no need for both. If you don't like accessing the undocumented _handle member of the object returned by Popen, then you can achieve the same result using the documented pid member and the Windows OpenProcess API.

Only on Python > 2.2. Note that the ctypes solution is only available to you if you are using Python 2.3 or higher. You can find it here: http://starship.python.net/crew/theller/ctypes/
You can add this method. # Kill the process with windows TASKKILL utility
import os
os.popen('TASKKILL /PID '+str(process.pid)+' /F')
