Kill a process that run in infinite loop - c++

Question

I create a process from c++ code, that run a python script.
STARTUPINFO si = {0};
PROCESS_INFOMATION pi = {0};
LPTSTR cmdArgs = _T("cmd.exe /k python myScript.py");
CreateProcess(NULL, cmdArgs, NULL, NULL, FALSE, CREATE_NEW_CONSOLE, NULL, NULL, &si, &pi);
The script run in infinite loop, for example:
while (1):
print("hello")
I want to kill the process but nothing really work.
I t ried TerminateProcess(), taskkill with pid - they report that process terminated but it still running.
How can I kill the process while it runnning?

LPTSTR cmdArgs = _T("cmd.exe /k python myScript.py");
CreateProcess(NULL, cmdArgs, NULL, NULL, FALSE, CREATE_NEW_CONSOLE, NULL, NULL, &si, &pi);
this code create cmd.exe process and it create python.exe process. question - for what create intermediate cmd.exe ?! you need direct start python.exe. use "python myScript.py" command line and start python.exe direct (if use unicode W api and empty application name - string must not be readonly (in your code it readonly - so you use A api, otherwice you got exception))
TerminateProcess not work - because you have handle of cmd.exe and you can terminate it. but not python.exe.
taskkill with pid - they report that process terminated but it still
running.
of course - pid belong to cmd.exe and it terminated. but python.exe still runing.
so again - solution very simply - direct exec target process, without cmd.exe
