How to Close Windows on PC, Mac, Android, and iPhone: A Complete Guide

Closing windows on your computer or mobile device is a basic but essential task, whether you’re trying to declutter your workspace, improve performance, or protect your privacy. To close a window, you usually just need to click or tap on a specific button or gesture, depending on your operating system. Once you close a window, it will disappear from your screen and any data or changes within it will be saved or discarded based on the application’s settings.

When you complete the action of closing a window, the application or document that was open in that window will no longer be active. If it was the only window open for that application, the application itself might shut down. It’s always a good practice to save any work before closing windows to avoid losing data.

How to Close Windows on PC, Mac, Android, and iPhone

Before diving into the steps, understand that closing windows helps declutter your digital space, potentially improves your device’s performance, and stops active processes that could be using up resources.

Step 1: Identify the window you want to close

Click or tap on the window you wish to close to make it the active window.

Different applications have different methods of indicating which window is active, but generally, the window in the foreground is the one you’re currently using.

Step 2: Locate the close button

On most PCs, this is usually an ‘X’ at the top right corner of the window. On Mac, it’s a red button at the top left corner. For Android and iPhone, it often involves swiping the window away.

The close button may look different depending on the application or the customizations you have applied to your operating system’s theme or settings.

Step 3: Click or tap the close button

Simply clicking or tapping on this button should immediately close the window.

Some applications may prompt you to save any unsaved work before the window closes, so always be prepared to confirm that you want to exit or save your progress.


Declutters workspaceHaving fewer open windows makes it easier to focus on the task at hand and decreases visual stress.
Frees up system resourcesClosing unnecessary windows can free up memory and processing power, potentially speeding up your device.

Potential data lossIf you close a window without saving your work, you might lose unsaved data. It’s crucial to make sure everything is saved before closing.
Interrupted workflowSometimes closing a window can disrupt your workflow, especially if you close something by accident.
Habit formationRelying on closing windows instead of organizing them might lead to poor digital organization habits.

Additional Information

Closing windows is straightforward, but there are some additional tips and insights that can enhance your understanding. For instance, many operating systems allow you to use keyboard shortcuts to close windows quickly. On a PC, you can often use ‘Alt + F4’ to close the active window. Mac users can use ‘Command + W.’ Knowing these shortcuts can speed up your workflow substantially.

Moreover, some applications have built-in features that allow you to close all windows at once or close all windows except the active one, which is useful when you’re working with multiple documents or tabs. It’s worth exploring the features of the applications you use most frequently.

Remember, closing a window doesn’t always mean the application has fully shut down; some continue running in the background and can be accessed from the system tray or dock. Always ensure you’ve completely exited a program if you’re done using it, especially if it uses a significant amount of resources.
