Closing an application on Windows is a simple task that anyone can do in just a few clicks. To quickly close an app, you can use three methods: clicking the ‘X’ button, using Task Manager, or utilizing keyboard shortcuts. Each method is straightforward, allowing you to efficiently manage your open applications.
How to Close an Application on Windows
Let’s dive into the specific steps for closing an application on Windows. These methods will help you smoothly shut down any app you no longer need running.
Step 1: Click the ‘X’ Button
Locate the ‘X’ button in the upper-right corner of the application window and click it.
This is the most common way to close an app. When you click the ‘X’, Windows sends a signal to the application to shut down gracefully.
Step 2: Use the Task Manager
Press Ctrl + Shift + Esc to open Task Manager, select the application, and click “End Task.”
Task Manager is like your control center. If an app isn’t responding, this tool force-closes it, freeing up system resources.
Step 3: Keyboard Shortcuts
Press Alt + F4 while the app is active to close it immediately.
Keyboard shortcuts are your speed-dial for tasks. This method works best when you need to close applications without a mouse.
Step 4: Right-Click the Taskbar Icon
Right-click the app’s icon on the taskbar and select “Close window.”
This method is handy when you have multiple windows open. It quickly targets the specific application you want to close.
Step 5: Use the File Menu
Click “File” in the application menu and select “Close” or “Exit.”
Some apps offer this old-school method, which is reliable and ensures all unsaved work prompts are visible.
After completing these steps, the application will close, freeing up RAM and CPU resources. You’ll notice smoother performance as your computer redirects power to other tasks.

- Keyboard shortcuts can speed up your workflow when multitasking.
