To force quit a frozen app on Windows 11 or Windows 10, press Ctrl + Shift + Esc to open Task Manager, right-click the app under Apps and select End task.
This guide covers that method and three more, Alt + F4, taskkill and PowerShell's Stop-Process, plus what to do when Task Manager will not open and why apps freeze in the first place.
Method 1: Use Task Manager (recommended)
Task Manager ends unresponsive programs on every edition of Windows 11 and Windows 10. Unsaved work in the frozen app is lost, so give it a few seconds first if it is busy saving or calculating.
- Press Ctrl + Shift + Esc, or right-click Start and select Task Manager.
- Select Processes in the left menu on Windows 11, or the Processes tab on Windows 10.
- Find the frozen app under the Apps section.
- Right-click it and select End task.
- Confirm the app window has closed, then close Task Manager and reopen the app.
Task Manager also lists background processes below the Apps section. End only the app you can identify, not entries you do not recognise.
Quick summary: 4 ways to force close apps on Windows
All four methods work on Windows 11 and Windows 10. Pick the one that matches how badly the app is stuck.
| Your situation | Use this method | Why |
|---|---|---|
| App is frozen but the desktop still responds | 1. Task Manager > End task | Shows every app, so you pick exactly the one to close |
| The frozen app is the active window | 2. Alt + F4 | One key press, no menus |
| Task Manager is slow or you know the program's file name | 3. taskkill in Command Prompt | Ends the process by name or PID, with /f to force it |
| You work in PowerShell or need to stop every copy of an app | 4. Stop-Process in PowerShell | Stops all instances by name, or one by ID |
Other routes, not counted in the four: Windows 11's taskbar End task option and the Ctrl + Alt + Delete security screen, both covered below.
Why apps freeze on Windows
An app freezes when it stops processing input, so Windows marks it as not responding. The causes below are the ones Microsoft names for its own apps, and they apply to most desktop programs.
| Cause | What happens | What to do |
|---|---|---|
| A long task is still running | The app is busy, and clicking more can make it stop responding | Let the task finish before you force quit |
| Add-ins or plug-ins conflict | An extension crashes or blocks the main app | Start the app without add-ins and re-enable them one at a time |
| Out-of-date files | Bugs fixed in later versions keep causing hangs | Install Windows and app updates |
| Not enough memory | Large files and many open apps exhaust RAM | Close other apps and check memory use in Task Manager |
| Files on a network or web location | The app waits on a slow or dropped connection | Save a local copy and test with that |
| Antivirus integration | Security software that hooks into the app slows it down | Update the security software rather than turning it off |
Method 2: Keyboard shortcut (Alt + F4)
Alt + F4 closes the active window. It works best when the app is slow but still reacting a little, because a fully hung app may ignore it.
- Click the title bar of the frozen app, or press Alt + Tab until it is selected, so it becomes the active window.
- Press Alt + F4.
- Wait a few seconds for the window to close.
- If the app still does not close, use Task Manager or taskkill instead.
Press Alt + F4 only when the frozen app is in front. With no window open, the same keys bring up the shut-down prompt.
Method 3: Command Prompt — taskkill command
taskkill ends a process by image name or process ID. Run tasklist first if you need the exact name or PID of the frozen program.
taskkill /im notepad.exe /f/im names the program's image (file) name, here notepad.exe; replace it with the frozen app's name. /f forces the process to end. Add /t to end any child processes it started, or use /pid followed by the process ID to end one specific copy. To close every program Windows reports as frozen, run taskkill /f /fi "STATUS eq NOT RESPONDING" /im *.
You should see: The app window disappears, and running tasklist again no longer shows the program.
Run Command Prompt as administrator to end a process started by another account or by the system. The NOT RESPONDING filter closes everything that is hung at that moment, so check tasklist first if you have unsaved work elsewhere.
Method 4: PowerShell — Stop-Process
Stop-Process stops processes by name or process ID on the local computer. It does not ask for confirmation for your own processes, and kill is a built-in alias for it on Windows.
- Select Start, type
PowerShelland open Windows PowerShell. - Type
Get-Processand press Enter to find the frozen app's process name and Id. - Type
Stop-Process -Name "notepad"and press Enter, replacing notepad with the app's process name. This stops every instance of it. - To stop one copy only, type
Stop-Process -Id 3952 -Confirm -PassThru, using the Id from step 2, and press Y to confirm. - For a process owned by another user, reopen PowerShell with Run as administrator and add
-Force.
Stopping a process can also stop processes and services that depend on it. Never stop system processes you do not recognise, and run PowerShell as administrator only when your own account cannot end the app.
End task from the taskbar in Windows 11
Windows 11 can add End task to the right-click menu of taskbar buttons. The switch lives on the Advanced settings page, called For developers before Windows 11, version 25H2. It is an extra route, not one of the four methods.
- Open Settings > System > Advanced, or System > For developers on earlier Windows 11 versions.
- Turn on End Task under the taskbar settings.
- Right-click the frozen app's button on the taskbar.
- Select End task.
On a work or school PC, organisation policy can disable the toggles on this page.
How to check the frozen app is fully closed
- Press Ctrl + Shift + Esc and check the app no longer appears under Apps or in the background processes list.
- In Command Prompt, run
tasklist /fi "IMAGENAME eq notepad.exe"with the app's name. No matching task means it has ended. - In PowerShell, run
Get-Process -Name "notepad". An error saying no process was found confirms it stopped. - Reopen the app. A fresh window that responds normally means the force quit worked.
When Task Manager won’t open
If the whole desktop is stuck, the shortcut that opens Task Manager may do nothing. Work down these symptoms from the least to the most disruptive fix.
Ctrl + Shift + Esc does nothing
The frozen app is holding the foreground or the desktop is busy.
- Press Ctrl + Alt + Delete to switch to the security screen.
- Select Task Manager and end the app from Processes.
- If Task Manager still does not appear, right-click Start and select Task Manager.
A full-screen app or game covers Task Manager
The frozen app stays on top of every other window.
- Press Windows logo key + D to show the desktop.
- Open Task Manager with Ctrl + Shift + Esc and select End task on the app.
- If the screen stays covered, press Ctrl + Alt + Delete, sign out, and sign back in.
Task Manager opens but the app will not end
The process is stuck in a state End task cannot interrupt, or it runs under another account.
- Open Command Prompt with Run as administrator.
- Run
taskkill /im appname.exe /f /twith the app's image name. - If the process still lists in
tasklist, save work in other apps and restart Windows.
The screen is black or the whole PC is frozen
The display driver or Windows itself has stopped responding, not only one app.
- Press Windows logo key + Ctrl + Shift + B to wake the display.
- If nothing responds after a minute, force restart the PC with the power button.

Force quit frozen apps on Windows: FAQs
How do I force quit a frozen app on Windows?
Press Ctrl + Shift + Esc to open Task Manager, select Processes, right-click the frozen app under Apps and select End task. The app closes straight away, and any unsaved work in it is lost.
What is the keyboard shortcut to force quit on Windows?
Alt + F4 closes the active window, and Ctrl + Shift + Esc opens Task Manager, where End task force closes the app. If neither responds, press Ctrl + Alt + Delete and open Task Manager from the security screen.
How do I close a frozen program when Task Manager will not open?
Press Ctrl + Alt + Delete and select Task Manager, or right-click Start and select Task Manager. If that fails, open Command Prompt as administrator and run taskkill /im followed by the program's file name and /f.
How do I force close every frozen app at once?
Open Command Prompt as administrator and run taskkill /f /fi "STATUS eq NOT RESPONDING" /im *. It ends every process Windows reports as not responding at that moment, so save work in other apps first.
Why do my apps keep freezing on Windows?
Common causes are a long task still running, conflicting add-ins, out-of-date app or Windows files, low memory, and files opened from a slow network location. Install updates, start the app without add-ins, and close other programs to narrow it down.
Why do my Microsoft apps keep freezing?
For Office apps, Microsoft names add-in conflicts, missing updates, large files, low RAM and files saved on network or SharePoint locations. Antivirus software that integrates with the app can also slow it down.
Does force quitting an app lose unsaved work?
Yes. End task, taskkill /f and Stop-Process stop the process immediately, so anything not saved is lost. Alt + F4 gives the app a chance to close normally, so try it first when the app still reacts, and save work in other open apps before you run a force-quit command.
Is it safe to force quit an app on Windows?
Ending a normal app is safe for Windows. Ending system processes is not, because stopping a process can also stop services that depend on it, and in an extreme case stop Windows itself.
How do I close a frozen app on a Mac?
Task Manager, taskkill and Stop-Process are Windows-only. macOS has its own Force Quit window and Activity Monitor, so force quit the app on a Mac with those tools instead.
Bottom line: the fastest way to force quit a frozen Windows app
Use Task Manager first, Alt + F4 when the app is already in front, and taskkill /f or Stop-Process only when End task fails. Task Manager shows exactly which app you are closing, while the commands force the process down when the interface cannot.
