How to Kill a Process in Windows 11

Method 1Using Windows Task Manager

Task Manager 📊, a built-in Windows utility, displays all active programs and background tasks on your computer. It also shows how much CPU, memory, disk and network each one is using. That makes it the first place to look when an app hangs, and the tool most people use to shut down unresponsive applications.

This closes the frozen program immediately. Windows doesn’t ask the app to save its work first, so anything unsaved in that program is lost. Use it when the program has stopped responding to normal clicks and the close button.

How to open Task Manager:

1. Press CTRL + SHIFT + Esc keys together on your keyboard. The Task Manager 📊 window should open on top of the frozen app. If it opens behind it, click its icon on the taskbar 🖥️.

OR

1. Press CTRL + ALT + DELETE, then click Task Manager 📊 on the screen. Task Manager should open. Use this route if the keyboard shortcut above does nothing.

Once Task Manager opens:

1. Click More details at the bottom if it looks simple. If you see only a small window with a short list of apps, this expands it into the full Task Manager 📊. If the button isn’t there, you already have the full view.
2. Go to the Processes tab at the top. In Windows 11 22H2 and later, Processes is the first item in the left-hand sidebar. In the original 21H2 release, it is a tab along the top. You should now see a list of apps, background processes and Windows processes.
3. Look through the list and find the program that’s frozen or using a lot of memory. A frozen app is often marked Not responding. To find a resource hog, click the Memory or CPU column header to sort the list from highest to lowest.
4. Select the program name. The row highlights. Check that you picked the right one, because ending the wrong entry closes that program too.
5. Do one of these:

   • Press the Delete key on your keyboard, OR
   • Right-click the program and choose End task, OR
   • Click the End task button at the bottom right. In some builds the button sits in the toolbar at the top of the window instead.

   The program window should disappear and its row should vanish from the list. If it stays, wait a few seconds and try again.

Task Manager 📊 helps you kill a process in Windows 11 when an app freezes or stops responding. Open the Processes tab, select the frozen program from the list, and click the End task button at the bottom right corner of the window. You can also right-click the program and choose End task, or press the Delete key on your keyboard to force it to close.

Don't end items you don't recognize, especially ones listed under Windows processes. Ending a core system process can make Windows unstable or force a restart. If you end the wrong app by mistake, just open it again from the Start menu.

A confirmation prompt may appear; click End process to finalize. This prompt usually shows up for system-related processes, and it warns that unsaved data will be lost. If you're not sure what the process is, click Cancel and look it up first.

Windows 11 lets you expand the view to manage child processes (smaller, related tasks running underneath a main application). Clicking the small arrow next to a main program name reveals this nested hierarchy. Managing child processes independently halts specific sub-tasks without closing the parent application.

Browsers and other multi-process apps often show up this way. If you end the main entry, all of its child processes close with it. If only one tab or helper is stuck, expand the entry and end just that one.

Method 2Using Command Prompt with taskkill

Why use this? Use Command Prompt if you prefer managing applications with text commands. It also helps when the desktop is so slow that clicking around in Task Manager is hard, or when you want to close a program by name without hunting for it in a list.

What happens when you do this? The program closes immediately without displaying confirmation pop-ups. As with Task Manager, unsaved work in that program is lost, so double-check the name before you press Enter.

Step 1Open Command Prompt or PowerShell

1. Search for Command Prompt or PowerShell in the Start menu and open it. A window with a blinking cursor should appear. In Windows 11 it may open inside Windows Terminal, which is normal.
2. Flag: If you need to close system processes, right-click and choose Run as administrator. Click Yes if the User Account Control prompt appears. Without admin rights, Windows may reply with "Access is denied" for protected processes.

Step 2See all running programs

First, list the running processes so you can confirm the exact name or ID. Enter the following command and press Enter:

tasklist

Output resembles this format. Scroll up if the list is long, and look for the name of the program you want to close:

Image Name PID Session Name Session# Mem Usage
========================= ======== ================ =========== ============
System Idle Process 0 Services 0 8 K
System 4 Services 0 144 K
msedge.exe 652 Console 1 26,528 K
winlogon.exe 740 Console 1 12,280 K

Step 3Stop a program by name

Command Prompt lets you kill a process in Windows 11 by typing a specific command when you know the exact name of the program. Open Command Prompt and type taskkill /IM msedge.exe /F to force Microsoft Edge or any other running software to quit immediately without needing the mouse. Here, /IM is followed by the image name (the .exe file name), and /F forces the program to close.

taskkill /IM ImageName /F

Example. Swap the program name for the one you want to close:

taskkill /IM msedge.exe /F

This action forces Microsoft Edge to quit. The command window should print a message saying the process was terminated. If you get a "not found" message instead, the name is wrong or the program isn't running.

Process IDs (PIDs), the unique numbers assigned to running applications in Task Manager, provide another termination vector. Targeting a specific numeric identifier terminates that exact instance. This is useful when several copies of the same program are running and only one is stuck. To see PIDs in Task Manager, open the Details tab and look at the PID column.

taskkill /PID 652 /F

Method 3Using PowerShell with Stop-Process

Why use this? PowerShell provides advanced scripting capabilities for managing single or multiple programs simultaneously. If you already work in PowerShell, you can close several stuck programs in one line instead of repeating a command.

What happens when you do this? The targeted applications terminate instantly. There's no warning and no chance to save, so be sure of the names or IDs first.

Step 1Open Windows PowerShell

1. Search for PowerShell in the Start menu and open it. A PowerShell window with a prompt should appear.
2. Flag: To stop system processes, right-click and choose Run as administrator. Accept the User Account Control prompt. The window title should then show that it is running as Administrator.

Step 2List all running programs

Start by listing what's running so you can pick your target. Enter the following command and press Enter:

Get-Process

Output resembles this format. Note the process name or ID of the program you want to stop:

Handles NPM(K) PM(K) WS(K) CPU(s) Id SI ProcessName
------- ------ ----- ----- ------ -- -- -----------
...
466 18 4544 23592 2.25 3440 1 msedge
...

Step 3Stop a program by name

Execute this command, substituting ProcessName with the actual target. Type the name or ID exactly as it appeared in the list:

Stop-Process -Name "ProcessName" -Force

Example. PowerShell usually returns to the prompt without printing anything when it works, so check Task Manager or your desktop to confirm the program closed:

Stop-Process -Name "msedge" -Force

Step 4Stop a program by process ID

To stop more than one program at once, execute this command:

Batch termination requires comma-separated Process IDs (PIDs)—the unique numeric identifiers assigned to running tasks. Entering an argument like "1234,5678" closes multiple unwanted applications simultaneously in Windows 11. Use the real PIDs from your own list, not the example numbers, and don't put spaces around the commas.

Stop-Process -ID 3440,652,740 -Force

Summary

Task Manager is the easiest way to kill a process in Windows 11 for most users by finding the program and clicking End task. Advanced users can also use command-line tools like Command Prompt or PowerShell when standard windows fail to respond or close normally. Start with Task Manager, and move to the command line only if it can't end the process or won't open.

• Task Manager is the easiest way for most users. Just open it, find the program, and click End task.
• taskkill command works when you like using the keyboard. Type a command and press Enter. It is handy when you know the program's exact file name.
• Stop-Process command in PowerShell gives you the most control and lets you stop multiple programs at once.

Mastering process termination keeps your Windows 11 workstation stable when applications like Microsoft Word freeze. Prompt intervention prevents performance degradation and guards against unsaved data loss. Still, ending a process is a last resort: wait a minute first if the app might just be busy, and save your work in other programs before you start closing things.
