In python 2.7 in windows according to the documentation you can send a CTRL_C_EVENT (Python 2.7 Subprocess Popen.send_signal documentation). However when I tried it I did no
try with
win32api.GenerateConsoleCtrlEvent(CTRL_C_EVENT, pgroupid)
or
win32api.GenerateConsoleCtrlEvent(CTRL_BREAK_EVENT, pgroupid)

read info about dwProcessGroupId, the groupid should be the same of the process id
