Wmic kill process

By the way, if you place this command in a batch script, remember to use “%%i” instead of “%i” for your parameters, or you’ll get an error message like
FOR /F documentation
Findstr documentation
Solution 2:
If the processes name difference is not very complex, e.g. if the name is always the same
you can use the /FI option of taskkill directly
==> taskkill documentation
Solution 3:
I used this in command line:
name variable can contains blank surround with ”
You should embed the value of the variable
into the command line:
If you use an older Python, try
Solution 2:
Maybe its because pid is a string,
idk if i am right but try
Solution 1:
Several changes:
The command_to_process needs back quotes (“) on both sides of the command.

This article is using wmic commands

. Wmic is a tool of the command prompt to get system information. The full form of wmic is the Windows Management Interface command

. The list of Commands for gathering information are mentioned below.

The command is used to get the computer’s serial number. This is very helpful to get the serial number of our bios. We will get our serial number instead of O. E. M.

  wmic bios get serialnumber  

Serial Number in cmd

wmic bios get serialnumber command

The command is used to get Mac Address is given below but there other be other ways also by which we can get our Mac Address. 

  wmic nic get macaddress :: Method 1
getmac :: Method  

mac address using cmd

This command helps to gather all information about a CPU i.e. name, device id, number of cores, max clock speed, status. This can also help us in figuring out our CPU specs. 

  wmic cpu  

We can also send attributes to get the particular details of a CPU in a better view. You may use a particular attribute to get particular details of CP.

  wmic cpu get caption, name, deviceid, numberofcores, maxclockspeed, status  


get cpu command

Given_Ram_Size (in bits) / 8 = New_Ram_Size (int bytes)

  wmic computersystem get totalphysicalmemory  

RAM in windows

In many cases, we need to know the size of the disc as well as the partition of our/someone’s disk. Here is the command to get the details of the partition of the disc. Here also, like in CPU, we can get the particular detail of the disc, like getting the name or size or type or getting everything in one shot.

 The size given here is also in terms of bits. We can convert it into byte by dividing the given size by 8.

Given_Ram_Size (in bits) / 8 = New_Ram_Size (int bytes)

  wmic partition get name,size,type  

Partition Details

wmic partition get name,size,type

These are the commands which can help us to get the list of all processes running on our computer, and we can also close them by using these commands. These commands are very useful to get to know what tasks are running on someone’s machine. It gives us a list of processes that are running in our background.

  wmic process list  

Process List

wmic process list command

We can terminate these tasks by using the command: 

  wmic process where name="name_of_file" call terminate  

Put the name of the ‘.exe file’ in place of “name_of_file” 


  wmic process list  

wmic process list

  wmic process where name="Calculator.exe" call terminate  

wmic process where name="Calculator.exe" call terminate

terminate calculator using cmd

  wmic product
wmic product get name,version  

wmic product

wmic product get name, version

Basic Volume Details

This command gives us the details of a particular volume of the disc. This also gives us the serial number of the volume of that disc.

  vol volume_letter:  

Replace volume_letter with the letter of the volume you wish to use.

Basic Volume Details

This command gives us the window’s version. This helps us figure out that if the updates are installed in our system or what is our window’s version. The command pop up a new window about windows

where we can see our Windows version.



This command gives us a list of all large files and files which are harmful. This can also help us to figure out which file is taking more space and we can also delete those files to clean some memory in the disc.



This command gives us all the basic information about our computer such as:

  • Host Name
  • OS Name
  • OS Version
  • OS Manufacturer
  • OS Configuration
  • Os Build Type
  • Registered Owner
  • Product ID
  • Original Install Date
  • Bios Version
  • Processor
  • Input Locale
  • Time Zone
  • & many more



This command gives us whole details of our hard disk where we can select volume get whole details of that volume.

::'disk part' will get us to an infinite loop.
 list disk
::'list disk' will give us the status and the size of the hard disk partition
 select disk_name
::Enter our disk name instead of 'disk_name' and our disk will be selected
 detail disk
::This will give us option which we can use to manipulate our disk
::This will finally help us to exit the infinite loop  






The WMIC tool was introduced in Windows XP Professional and has been included in every version of Windows since. Furthermore, it can be used to manage every Windows version since Window 95, although 9x and NT require the Microsoft WMI Core add-on to be installed.

In this post, I will discuss wmic commands I find very useful from a forensic standpoint.

Windows Management Instrumentation

 — это базовая технология как для управления так и для слежения за работой платформы Windows.

Только пользователи локальной группы «Администраторы» имеют право запускать WMIC.

В основе структуры данных в WBEM лежит Common Information Model (CIM), реализующая объектно-ориентированный подход к представлению компонентов системы. C IM является расширяемой моделью, что позволяет программам, системам и драйверам добавлять в неё свои классы, объекты, методы и свойства.

Важной особенностью WMI является то, что хранящиеся в нём объекты соответствуют динамическим ресурсам, то есть параметры этих ресурсов постоянно меняются, поэтому параметры таких объектов не хранятся постоянно, а создаются по запросу потребителя данных. Хранилище свойств объектов WMI называется репозиторием и расположено в системной папке операционной системы Windows:

Так как WMI построен по объектно-ориентированному принципу, то все данные операционной системы представлены в виде объектов и их свойств и методов.

Все классы группируются в пространства имен, которые иерархически упорядочены и логически связаны друг с другом по определенной технологии или области управления. В WMI имеется одно корневое пространство имен Root, которое в свою очередь имеет 4 подпространства: CIMv2, Default, Security и WMI.

Классы имеют свойства и методы и находятся в иерархической зависимости друг от друга, то есть классы-потомки могут наследовать или переопределять свойства классов-родителей, а также добавлять свои свойства.

Свойства классов используются для однозначной идентификации экземпляра класса и для описания состояния используемого ресурса. Обычно все свойства классов доступны только для чтения, хотя некоторые из них можно модифицировать определенным методом. Методы классов позволяют выполнить действия над управляемым ресурсом.

:/>  Удалила интернет эксплорер как восстановить

Каждому экземпляру класса можно обратиться по полному пути, который имеет следующую структуру:

– имя компьютера

– название пространства имен

– имя класса

KeyProperty1=Value1, KeyProperty2=Value2
– свойства объекта и значения, по

которому он идентифицируется.

Пример обращения к процессу с именем «Calc.exe», который запущен на локальной машине:

Экземпляры классов могут генерировать события, к которым можно подписываться. При наступлении события WMI автоматически создает экземпляр того класса, которому соответствует это событие. Такой механизм удобно использовать для выполнения определенной команды при наступлении определенного события, то есть следить за состоянием объектов операционной системы.

Общая безопасность в WMI реализуется на уровне операционной системы, а дополнительная политика безопасности основана на уровнях пространств имен и протокола DCOM. То есть если пользователь не имеет права делать какое-то действие через операционную систему, он не сможет это сделать и через WMI
. Если же пользователю дано какое-то право в операционной системе, то это ещё не означает, что это право будет и в WMI, так как в WMI действуют дополнительные параметры безопасности на уровне пространств имен.

Для вызова удаленных процедур WMI использует модель DCOM. В случае если возникает ошибка «Dcom Access Denied» то действия будут следующими: меня «Выполнить»->»dcomcnfg»->»Службы компонентов(Component Services)->Компьютеры->Мой компьютер->Свойства(правая кнопка мыши)->вкладка Безопасность COM Уровни олицетворения могут принимать следующие значения:

Уровни аутентификации (подлинности) могут принимать следующие значения:

 — оснастка консоли управления MMC для настройки WMI на локальном компьютере.

 — консольная утилита управления WMI локального компьютера.

 — графическая утилита для взаимодействия со структурой WMI на локальном или удаленном компьютере.

 — консольная утилита для взаимодействия со структурой WMI на локальном компьютере.

– MOF compiler for extending the WMI structure, managing the WMI class library, and restoring the repository.

How do I Taskkill a PID that keeps changing?

cmd /c FOR /F “usebackq tokens=2 skip=3” %%i IN (

tasklist /fi "services eq NlaSvc"

) DO taskkill /PID %%i

Pass PIDs from tasklist and kill processes with tasklist

 FOR /F "usebackq tokens=2" %i IN (`tasklist ^| findstr /r /b "[0-9][0-9]*[.]exe"`) DO taskkill /pid %i

  • The command_to_process needs back quotes (“) on both sides of the command.
  • Pipes (“|”) inside of the command_to_process need to be escaped with a caret (“^”).
  • Your findstr command would match all processes that have a digit before the “.exe”. For example, “myapp4.exe” would also have been killed. The version I provide will match process names solely containing numbers.
  • The “skip=2” option would skip the first two lines output from findstr, not tasklist. Since the regular expression won’t match anything in the first two lines output from tasklist, you’re safe to remove the skip option.

By the way, if you place this command in a batch script, remember to use “%%i” instead of “%i” for your parameters, or you’ll get an error message like

i was unexpected at this time.

  • FOR /F documentation
  • Findstr documentation

If the processes name difference is not very complex, e.g. if the name is always the same
you can use the /FI option of taskkill directly

 taskkill /FI "IMAGENAME eq your_image_name_here.exe"


==> taskkill documentation

I used this in command line:
name variable can contain blank surround with ”

How to find a process pid with wmic and kill it with taskkill

 for /F "skip=2 tokens=2 delims=," %a in (
  'wmic process where " .... " get ProcessID^,Status /format:csv'
) do taskkill /pid %a


Now you have an output from


with an aditional line at the start (from here the skip), with fields separated with commas (the delim), and three fields included: the node (computername) that is automatically added, the processid (the second token) and a final status field that will not be used but allows us to retrieve the second token in the line without the ending CR

Or you can add an extraditional


command to your initial line

 for /f ... %a in ( ... ) do for %b in (%a) do taskkil /pid %b


This traditional


loop will remove the CR character from the retrieved wmic data that is in %a.

I had a similar problem where I had to stop a task only knowing the name of the running file. The solution was:

 for /f "tokens=2 delims=," %%a in (
    'wmic service get name^,pathname^,state /format:csv ^| findstr /i /r /c:"SomeServer\.exe.*Running$"'
) do sc stop "%%a"


This will stop the process by name. Maybe you can use the file name instead of the PID?!?

Python program that force kills current program using PID, In Windows, os.kill (pid, signal) is implemented via TerminateProcess (hProcess, signal), but only for values ​​of signal other than 0 and 1. The value of signal is used as the process exit status. We’d like this to be 1 typically for a forced termination, but os.kill is badly designed, so just use 3.

Python program that force kills current program using PID [duplicate]


is just a string that consists of three characters. You should embed the value of the variable


into the command line:

   os.system(f"ftaskkill /f /pid {pid}")

If you use an older Python, try

   os.system("ftaskkill /f /pid {}".format(pid))

Maybe its because pid is a string,

idk if i am right but try

os.system("taskkill /f " + pid)
