PID (Process ID) is a short form for process identifiers. A PID is a unique number that identifies each running process in an operating system, such as Linux, Unix, macOS, and Microsoft Windows. Task Killer can help you to kill (close or stop) the running apps of your device by ending one or more tasks or processes. Processes can be ended by PID or image name and Taskkill has replaced the kill tool. In this article, we shall discuss “Task Kill vs Stop Process: How to search for a service PID”. Please see User account and process management in Linux, Handy Shutdown commands available in Windows, and How to stop Windows from applying updates.
Note: In order to kill a process via the Command Prompt or PowerShell, you need an Administrator (elevated) privilege.
Reasons to forcefully kill or stop a process in Windows
As an Administrator from time to time, you may need to kill a service that is problematic and stuck or start a service that has refused to start.
Killing a service that is stuck or has refused to start will save you the time of restarting or rebooting a Server.

How to Kill a Process?
To have this done, you will need to search for the PID of the service. To determine the name of a service, this can be found in the following ways.
From the “services.msc” window (Also from the Task Manager, You can also access the services tab).
To determine the service PID, I will be using the “sc queryex” command to query the service name of the application. lso, launch Command Prompt with Administrators privilege and run tasklist to see all of the running processes.
Note: Since the list might be very long, you can use a pipe character with more command as shown below
tasklist | moreSteps for querying a service name
Launch an elevated Command Prompt (CMD): Use the following command below with the service name from the command prompt.
sc queryex servicename
Kill a service
To kill a service, launch the command prompt, the PID is paramount as this will be used to kill the service. See the images above on how to obtain the process ID (PID).
- Launch an elevated Command Prompt and
- Type the following command below to kill the service
taskkill /f /pid [PID]Where [PID] is the value associated the service name as shown above.
Note: The /f flag is used to kill the process forcefully. Failure to use the /F flag will result in nothing happening in some cases
Alternatively, we can also use the Task Manager to kill a service. For more information on using the Task Manager.
Note: Ensure absolute care is taken on what service you are killing though. If you kill a critical Windows service you may end up forcing the machine to reboot on its own in order to have this it resolved.
Filtering options available to Taskkill
Below are other filtering options variables and operators that can be used with “taskkill”.
| Variables | Operators |
| STATUS | eq (equals) |
| IMAGENAME | ne (not equal) |
| PID | gt (greater than) |
| SESSION | lt (less than) |
| CPUTIME | ge (greater than or equal) |
| MEMUSAGE | le (less than or equal) |
| MODULES | |
| Services | |
| WINDOWSTITLE |
These variables and operators can be used with the /FI filtering flag.
Example 1
You wish to end all processes that has a window title that starts with “DriveBit”:
taskkill /FI "WINDOWTITLE eq DriveBit*" /FExample 2
Kill all the process running under a user account
taskkill /FI "USERNAME eq Administrator" /FExample 3
Kill a service running on a remote desktop (server)
taskkill /S AnsibleServer /U RemoteAccountName /P RemoteAccountPassword /IM chrome.exe /FPlease see Process Explorer (SysInternal Tools), how to use SysInternals Live Tools, how to download and use Windows SysInternals tools locally, and Process Explorer (Replace built-in Task Manager).
Killing a process via PowerShell
To Kill a process via PowerShell is somewhat similar to killing a process using CMD. You also need elevated (Admin rights) to have this done.
Launch PowerShell as an Administrator. Type the command Get-Process to see the list of running processes as shown below
Get-Process1: To kill a process by its name: Execute the following cmdlet as shown below.
Stop-Process -Name "ProcessName" -ForceTo kill a process by its PID, run the command as shown below.
Stop-Process -ID PID -ForceI hope you found this blog post helpful on “Task Kill vs Stop Process: How to search for a service PID”. If you have any questions, please let me know in the comment session.
