The fastest way depends on your operating system

Windows and Mac remove apps differently, so the method you use depends on which one you have. On Windows, you go through Settings or the Control Panel. On Mac, you drag the app to Trash or use the Finder. Both take less than a minute once you know where to look. The steps below cover each system separately.

Before you remove anything, close the app completely — do not just minimize it. Some programs lock their own files while they are running, and Windows or Mac will not let you delete them until they shut down fully.

Key Takeaways

  • On Windows 10 and 11, open Settings, go to Apps, then Apps & Features, find the program, and click Uninstall.
  • On Mac, drag the app from Applications to Trash, then empty Trash to finish the removal.
  • Some programs leave behind files in hidden folders even after you remove them; you can delete these manually if the app reinstalls or causes problems.
  • Restarting your computer after removal clears temporary files and prevents conflicts with other programs.
  • Built-in apps on Windows and Mac cannot be removed the same way, though you can hide or disable most of them.

Removing apps on Windows 10 and Windows 11

Open Settings by pressing the Windows key and typing "Settings," then press Enter. Once Settings opens, click on Apps in the left sidebar. Then click Apps & Features. You will see a list of every program installed on your computer, sorted by size or name depending on your view.

Find the app you want to remove. If the list is long, use the search box at the top and type the program name. Click on it once to highlight it, then click the Uninstall button that appears. Windows will ask you to confirm — click Uninstall again. Some programs will open their own removal window and ask you questions about what to keep; follow those prompts and click Finish when done.

If Uninstall is grayed out or does not work, the program may be built into Windows. You can disable it instead: right-click the app name and select Uninstall, or look for a Disable option. If neither appears, the app cannot be removed through Settings.

Removing apps on Mac

Open Finder and click Applications in the sidebar. You will see a folder full of all your installed programs. Find the app you want to remove, click it once to select it, then drag it to the Trash icon in your dock. You can also right-click the app and select Move to Trash.

Dragging to Trash does not fully remove the app — it only moves it to a holding area. To complete the removal, right-click the Trash icon in your dock and select Empty Trash. Once you empty Trash, the app is gone and cannot be recovered.

Some Mac apps come with their own uninstaller. If you see an Uninstaller file inside the Applications folder alongside the app, double-click it and follow the prompts instead of dragging to Trash. This method removes the app and any related files it created.

What happens to leftover files after removal

When you remove an app, the main program folder disappears, but some programs leave behind settings files, caches, and preferences in hidden folders. On Windows, these usually sit in AppData. On Mac, they hide in Library. Most of the time these leftover files cause no problems — they take up minimal space and do not affect other programs.

If an app reinstalls itself, crashes repeatedly, or causes errors even after removal, the leftover files may be the cause. You can delete them manually, but this requires showing hidden files on your system. On Windows, open File Explorer, click View, then check the box for Hidden Items. On Mac, press Command+Shift+Period in Finder to show hidden files. Navigate to the app's folder and delete it, then restart your computer.

Removing built-in apps you cannot uninstall

Windows comes with apps like Mail, Calendar, Photos, and Groove Music that cannot be removed through Settings. You can hide them from your Start menu instead: right-click the app tile and select Unpin from Start. This removes it from view without deleting it.

If you want to remove a built-in Windows app completely, you can use PowerShell, but this requires typing commands and carries a small risk of system problems if you remove the wrong thing. Most people find hiding the app sufficient. On Mac, built-in apps like Mail and Calendar also cannot be removed, but you can delete third-party apps freely.

Restart your computer after removal

After you remove an app, restart your computer. This clears temporary files the program may have left in memory and prevents conflicts if you install a different version of the same app later. Restarting takes a few minutes and is the safest way to make sure the removal is complete.

If you removed multiple apps, restart once after you finish removing all of them rather than restarting after each one. This saves time and achieves the same result.

Frequently Asked Questions

Can I undo removing an app?

No. Once you empty Trash on Mac or confirm Uninstall on Windows, the app is gone. You can reinstall it from the Microsoft Store, Apple App Store, or the program's website, but you will need to set it up again from scratch. Keep the installer file if you think you might need the app later.

Why does an app keep coming back after I remove it?

Some programs reinstall themselves through scheduled tasks or startup scripts. On Windows, open Task Scheduler and look for the app name in the list, then disable any tasks tied to it. On Mac, check System Preferences under Login Items and remove the app from there. You may also need to delete leftover files in hidden folders.

Is it safe to delete files in AppData or Library folders?

Only delete files you know belong to the app you removed. Deleting the wrong folder can break Windows or Mac. If you are unsure, leave the files alone — they use very little space. If you must clean them up, create a backup of your entire computer first.

What if the Uninstall button does not work?

Close the app completely and try again. If it still does not work, restart your computer and try once more. On Windows, you can also try removing the app in Safe Mode: restart, hold Shift while clicking Restart, then go to Troubleshoot and Safe Mode. If nothing works, the app may be corrupted and you may need to reinstall it before removing it again.
