I've been trying to terminate a video converter application process after it run conversions for five seconds (or you could say after a given time). This is the code I've been tying to use,
#echo off
TASKLIST
TIMEOUT /T 5 /NOBREAK
TASKKILL /IM /F /T FileRx.exe
But it doesn't kill the process. Can someone shed some light on what I'm missing here?
You need to be careful about the order of the taskkill switches. Try the following:
taskkill.exe /F /IM FileRx.exe /T
The process name should be right after /IM. See taskkill /? for the examples.

In short, I need to start 1.bat, that can CALL or START 2.bat to execute TASKKILL /im explorer.exe /f /t but keeps "1.bat" running (or reopens it) once "2.bat" is finished. The difficulty is, I need to keep the /t switch in TASKKILL to make it transferable.
Full Explanation:
I have several older laptops running Windows 7 x64. They will run games, but only if I use Task Manager to end Explorer, it's associated processes and stop several unneeded services. This frees up RAM and CPU to start games via Task Manager..
To avoid ending each process/service individually every time, I wrote 2 cmd batch files:
1) Options.bat -- (SHORTENED)
#echo off
:begin
echo (0) Kill Processes
echo (1) Run [game]
SET /p op=Select Task:
if "%op%"=="0" goto killall
if "%op%"=="1" goto op1
killall:
CALL "C:\TK.bat"
cls
goto begin
op1:
start " " /realtime "C:\[exe path]"
goto exit
:exit
exit
2) TK.bat -- (SHORTENED)
net stop [service]
taskkill /im explorer.exe /f /t
taskkill /im [specific process].exe /f /t
Both of which work as intended - provided I initially start Options.bat via Task Manager.
Problem: when I run Options.bat from Windows Explorer (even "Run As Administrator") and call the TK.bat script to run TASKKILL /im explorer.exe /f /t it does work, but also closes the CMD window, when i want it to return to the options selection. This does make sense when i'm using the "tree" attribute for TASKKILL.
However, if I run Options.bat via Task Manager, and CALL TK.bat, it will execute the commands (without closing itself) then return to the task selection - which is exactly what i want to happen!
I assume this is because it is running as the Local System account via Task Manager and not mine or the built in Administrator account?
I have tried the RUNAS command within Options.bat -
RUNAS /user:Adminstrator "C:\TK.bat"
which runs TK.bat, executes the TASKKILL command and then RUNAS again to return to the first batch file in my username. This does work, but I still have to press enter at each password prompt.
I have also tried numerous variations of the TASKKILL /FI switch:
TASKKILL /fi IMAGENAME ne cmd.exe /im explorer.exe /f /t`
TASKKILL /fi USERNAME eq [name] /fi WINDOWTITLE ne Options.bat /im explorer.exe /f /t
Which, I thought, would end all processes "not equal" to cmd.exe/Options.bat but I cannot get it to work.
Question: Is there a way of executing the TASKKILL /im explorer.exe /f /t within TK.bat, that will not close the currently running batch file and without having to run it from Task Manager? Perhaps a different command or giving the Options.bat some sort of elevated authority to stop it from being closed when Explorer.exe /t is ended. Ideally, without installing separate 3rd party tools?
I know I could edit the batch file to end explorer.exe, end each associated .exe and then stop the services I do not need, individually, but this is time consuming and defeats the point of writing the file to make it automated and transferable (if needed).
Any help would be greatly appreciated and I can upload the full code of both batch files, if that would help.
Strangely enough, the simple taskkill /F /IM explorer.exe & start explorer command does this task. I don't know why, but it works.
To prevent taskkill /im explorer.exe /f /t from killing the cmd instance which is executing your batch file, You need to break the parent-child relationship between that particular instance of cmd.exe and explorer.exe.
The trick is to use two extra instances of nested cmds. The first one launches the second one and terminates immediately so the second instance becomes an orphaned process which can not be determined as descendant of exeplorer.exe. At this point the second instance can safely execute taskkill /im explorer.exe /f /t
start "Chain breaker" /min cmd /d /c start "Orphaned Process" cmd /d /c Options.bat
The above can be used from Command Prompt or from another batch file.
You can also incorporate this technique directly in to the Options.bat file, But extra logic is needed for Options.bat to determine when to launch itself in nested cmd and when to execute the actual code.
A sample script demonstrating the concept would be:
#echo off
setlocal EnableExtensions DisableDelayedExpansion
for /F "tokens=3 delims=:" %%L in ("%~0") do goto %%L
REM Reinvoke the batch file forcing it to jump to the :main label
start "Chain breaker" /min cmd /d /c start "Orphaned Process" cmd /d /c #"%~d0\:main:\..%~pnx0"
exit /b
:main
taskkill /im explorer.exe /f /t
echo I'm alive
pause
exit /b
I am unable to call a bat process within another bat.
This is the situation.
I have a n1.bat that basically contains:
TITLE "n1.bat"
...
...
start /b /MIN "n2.bat"
...
The n2.bat contains:
TITLE "n2.bat"
...
...
start someother.bat
start another.bat
exit
Now I use a third bat (n3.bat) that must kill everything.
TITLE "n3.bat"
...
TASKKILL /F /T /PID n1_PID
...
exit 0
Unfortunately when n3.bat ends a window called n1.bat - n2.bat remains active (the echo output belongs to n2.bat).
I tried to kill it in some ways:
1- Tried to get the process pid from tasklist -> there is no process called n2.bat or similar
TASKLIST /V /NH>Tasks.txt
FOR /F "tokens=2 delims= " %%n2_pid IN ('FINDSTR n2.bat Tasks.txt') DO SET PID=%%n2_pid
TASKKILL /PID %n2_pid%
2- Trying to use TASKKILL /F /FI "WINDOWTITLE eq n2.bat" -> no process found
I tried the previous solutions also starting n2.bat with
start /min "n2.bat" (so without /b)
with no success.
The only way I manage to kill it is to calling
TASKKILL /F /IM cmd.exe
that I really would like to avoid since it obviously kills all opened cmd.
Any ideas to retrieve the guilty pid?
I am a beginner.I just went curious about cmd so I want to make a batch file that kills the active windows and shutdown/restart the computer safely.
I came across commands like-
taskkill /im "program.exe"
tasklist
shutdown -s
But I want to close all active windows but not forcefully.
If there a specific command or some combination of commands please do mention.
Thanks in Advance.
PS- I came across powershell but I want to know if i can achieve this using batch file (cmd commands) .Below is the link
How to close all windows
If you perform a treekill on explorer.exe, it will close all other programs except background processes. Those batch scripts will only work if they are called in an exceptional manner that makes them background processes, system processes or if they are not a child process of explorer.exe.
Here's the fastest reference implementation of my treekill explorer method
#echo off
echo closing all programs...
taskkill /f /t /im explorer.exe
explorer.exe
Here's an example implementation of my treekill explorer method combined with hibernate to make a fast shutdown and startup script.
#echo off
echo shutting down...
echo closing all programs...
taskkill /f /t /im explorer.exe
echo hibernating...
shutdown /f /h
echo restoring...
explorer.exe
echo thanks you for using JessieTessie's fast shutdown and startup.
You can do
#echo off
#powershell Get-Process | Where-Object {$_.MainWindowTitle -ne ""} | stop-process
taskkill /f /im explorer.exe
It will execute powershell command that will find and close all running programs that isn't hidden or evelated using windowtitle.
But it will close all apps including yours.
To prevent that you need to recode it from c++ (you can use system("somecommand") from windows.h) and before executing closeAll commands put freeconsole() in code. But you will need to find how to get console back.
title Kill all running apps

I'm trying to produce a batch file that can check to see if a process is running such as a game, photoshop, or media and terminate a specific process. In this case 'f.lux' considering it dims the screen and can affect color quality. I've looked for some answers on here for this with no luck, as most of the content is older and I'm not sure how much has changed in Windows 10. So far here is what I have picked up off of some other posts.
tasklist /FI "IMAGENAME eq example_process.exe" 2>NUL | find /I /N "example_process.exe">NUL
if "%ERRORLEVEL%"=="0" taskkill /im f.lux.exe
Not sure how correct this is, so any advice or help would be appreciated.
Thanks.
taskkill /im f.lux.exe
either this or
taskkill /f /im f.lux.exe
See taskkill/?
Just change to your task to be killed instead of iexplore.exe task in this example :
#echo off
set task=iexplore.exe
set Active_task=0
for /f %%q In ('tasklist') DO (if /i "%%q" EQU "%task%" set Active_task=1)
if %Active_task% EQU 1 (
Taskkill /PID %task% /F
)
Pause
I'm capturing the PID in a variable which I kill later
IF NOT "%SERVICE_PID%" == 0 taskkill /pid %SERVICE_PID% /t /f
though everytime I do this in a batch file it makes my computer restart because it kills some system process
the service pid should be a user defined service launched from cmd
I dont understand why it keeps making my machine croak.
When I run "taskkill /pid %SERVICE_PID% /t /f" on the command line it works fine! =/
help!
Setting SERVICE_PID
FOR /F "tokens=4 delims= " %%A IN ('sc queryex myservice ^|FIND "PID"')
DO SET SERVICE_PID=%%A
I found that using this will get the proper PID:
for /f "tokens=1,2,3,4 delims=/ " %%a in ('sc queryex ServiceName ^|FIND "PID"') do set PID=%%c
taskkill /pid %PID% /t /f
Then it works like a charm.
Try removing /f option, it forces to terminate a process, so system processes might get terminated forcefully without notification.
I am suspecting you are trying to kill some system processes in the batch script, in the sense that in your list of PIDs there might be some system process IDs as well.
Thanks
Make sure you have enabled delayed expansion. See the HELP SET for an explanation.
Insert this line
SETLOCAL ENABLEDELAYEDEXPANSION
as the first line of your batch file.
and use !SERVICE_PID! instead of %SERVICE_PID% to get the environment variable.
taskkill /fi "IMAGENAME eq idsm.exe" /fi "CPUTIME gt 00:30:00"
Image Name PID Session Name Session# Mem Usage
========================= ======== ================ =========== ============
idsm.exe 4556 Console 0 38,328 K
I got the this result, in the same command line how to kill this process, its should run automatically, means how to use this PID for killing
I found this the most reliable
net stop SERVICE_NAME
timeout /t 10
for /f "tokens=1,2,3,4 delims=/ " %%a in ('sc queryex SERVICE_NAME ^|FIND "PID"') do set PID=%%c
if not %PID% == 0 taskkill /pid %PID% /f
timeout /t 10
net start SERVICE_NAME
The timeout is arbitrary.
The first timeout gives service a chance to stop itself properly for some extra amount of time.
The second timeout allows the operating system to react, otherwise you may end up with
The service is starting or stopping. Please try again later. and service will not restart.
I am checking if service is not stopped by if not %PID% == 0 and force killing it if necessary. The /t flag was unnecessary in my case.
