I have several python.exe processes running on my Vista machine and I would like to kill one process thanks to the Windows task manager.
What is the best way to find which process to be killed. I've added the 'command line' column on task manager. It can help but not in all cases.
is there a better way?
Please consider replace Task Manager with the more powerful Process Explorer
here is a demo:
When I right clicked python in task manager and clicked open file location (win 10) it opened the plex installation folder so for me it is Plex that uses Python.exe to slow my computer down, shame as I use plex all the time for my Roku. Just have to put up with a slow computer and get another one.

I'm trying to achieve something ; I created a exe file, that automatically force shutdown the computer at 11 pm.
I would like to make this script impossible to stop or crash, or even make the entire system crash if the program is closed.
How can i achieve this ?
Note :
I'm on a laptop, running windows 10. I made a python file, and i converted it in an exe file with py installer. Then i created a shortcut to that exe file that run the program with admin rights
If you mark the process as critical Windows will trigger a blue screen crash if that process is stopped/killed.
There is information about how to do this here
Note: Although it is possible to do this, it is not a good idea to do so. For example as suggested by Anders, use a Scheduled Task. Having the system crash could result in information loss, or other unintended consequences.
Create a Windows service. You can deny Administrators trying to stop/pause the service, that should slow them down a little bit.
Or since we are talking about triggering something at a specific time, you might want to use the task scheduler instead.
In any case, you will never fully lock down something like this from an Administrator since they can always take ownership and modify the ACL.
What is the correct way to have python schedule (by daniel bader) persistently run. I currently run the job by having a terminal open, connected to a VM where the scripts actually run. There I run python "scheduler.py" - where scheduler.py has all the jobs.
But when the connection closes, or I close the terminal, the scheduler stops.
Any easy solutions to fix this?
You have a couple options here. You are starting the process in your ssh session, but then killing the ssh session, which then kills the process.
One way to handle this, would be to have the VM run the script on startup. You could set the script as a service, so even if it goes down for some reason it will come back up. Read into init.rc for info on how launch a script at boot on linux. I'm not well-versed in Windows any more but I believe there is a way to do the same.
Another option is to keep the session open by connecting to it with screen or tmux. This article explains the problem some and gives you a few different ways to work around the issue: https://www.tecmint.com/keep-remote-ssh-sessions-running-after-disconnection/
I want a python script that terminate an aplications when I RUN another program.
Example: if I run vlc media player that will close kodi.exe
Or any other options to do this ?
It seems to me that what you have to do is enumerate processes by name, determine which to kill, and then kill it (the last part may be cumbersome a bit).
Did you have a chance to look at the following questions and their answers (they illustrate how to handle all of the steps above)?

Is it possible to kill a process on Windows from within Python?
I've written a lot of python scripts. Now I want to run it on another computer which running non-stop to crawling, analyzing data and update to an sql database.
Normally I open a command prompt and run the scripts:
python [script directory]
But with many scripts I have to open many cmd and every script call an python interpreter, so It end up with huge mess using a lot of memory.
What should I do to manage these scripts.
You haven't specified what OS your server is, but assuming that it's a Linux server you should probably research a process management tool such as Supervisord or Systemd. These are tools designed to run and monitor your program automatically, and even restart it if it crashes.
If you're using Ubuntu 16.04 then it comes with Systemd out of the box, however I personally find Supervisord easier to configure and use for simple tasks.
These programs won't necessarily help with your memory consumption issues however. Sure you can place caps on memory use for a process, but that's not really going to help you if it stops your program from working. You're probably best to re-evaluate your code and look for ways to reduce its memory footprint or use a server with more ram.
EDIT:
You've just added that the OS is Windows 10, which makes the above irrelevant. You can use the Windows Task Scheduler to automatically execute long running tasks.
you can use pythonw *.py , and it will run in background.
I wrote a temperature logger Python script and entered it as a scheduled task in Windows XP. It has the following command line:
C:\Python26\pythonw.exe "C:\path\to\templogger.py"
It writes data to a file in local public folder (e.g. fully accessible by all who login locally).
So far, I was able to achieve this objective:
1. Get the task to run even before anyone logs in (i.e. at the "Press Ctrl+Alt+Del" screen)
But I'm having problems with these:
1. When I log in, log out, then log back in, the scheduled task is no longer active. I can no longer see it in the Task Manager's Processes tab. I suspect it closes when I log out.
2. I tried to set the task's "Run As..." property to DOMAIN\my-username and also tried SYSTEM, but problem #1 above still persists.
SUMMARY:
I want my program to be running as long as Windows is active. It should not matter whether anyone has logged in or out.
P.S.
I asked the same question in Super User, and I was advised to write it as a service, which I know nothing about (except starting and stopping them). I hope to reach a wider audience here at SO.
Is it possible to run a Python script as a service in Windows? If possible, how?

Your scenario is exactly the required use case for a service, unfortunately tasks are ill suited for what you are looking to do. That said writing services in python is not a walk in the park either, to ease the pain here is a few links I have perused in the past:

http://mail.python.org/pipermail/python-win32/2008-April/007298.html
I used the second link in particular to create a windows scripts that was then compiled to a executable service with py2exe and installed with SrvAny.
