How to Force Quit an Unresponsive App on Windows

For programs that still respond, the basic way to close them is to click the X icon at the top-right of the window. This sends the standard close command and gives the program a chance to finish what it is doing before closing. Using Alt + F4 does the same thing for the active app window, though it can be easy to close the wrong window when multiple monitors or apps are open. Depending on the program, this method either fully ends the process or sends the app to the system tray. Tools such as Discord, Spotify, Slack and Telegram typically stay running in the background, while Word, File Explorer, Notepad and Paint close as expected. Apps that do not fully close often offer File > Quit or File > Exit, sometimes with Ctrl + Q, and right-clicking their system tray icon and choosing Quit or Close usually works as well.

When an app freezes and does not respond to a normal close request, Windows users can turn to Task Manager, which is the closest equivalent to force-quitting on a Mac. It can be opened with Ctrl + Shift + Esc or by right-clicking an empty spot on the taskbar and choosing Task Manager. The Processes tab shows everything running on the computer. Entries can be sorted by clicking Name or searched with the box at the top, and clicking a header such as Memory sorts by resource use. A number next to an app name means multiple grouped processes. To force a process to close, the user can click it and hit End task in the top-right, or right-click it and choose the same option. This forcefully terminates the process without allowing a proper shutdown, so any unsaved work will be lost. Once the frozen program closes, it can be opened again.

The Windows Explorer entry under Windows process requires special care. Explorer controls File Explorer and many visual elements of Windows, including the taskbar, so Task Manager shows a Restart task option instead of simply ending it. If the Explorer process is ended by another method, users can click Run new task in Task Manager and enter explorer.exe to restart it.

A quicker method for ending unresponsive programs is available in the Settings app. Pressing Win + I, then going to System > Advanced, allows users to enable the slider next to End Task. After that, a new option appears when right-clicking an open app on the taskbar. Users should be careful to select the right command, because End task destroys the process without asking, while Close window sends the normal shutdown request.

If these methods do not close a frozen app, the Details tab on the left side of Task Manager offers another step. There, users can find the stuck process, right-click it and choose End process tree to attempt a more forceful closure that ends all related processes.
