The fastest way to uninstall an app depends on your operating system

On Windows, open Settings, go to Apps > Apps & Features, find the program you want to remove, click it, and select Uninstall. On Mac, open Applications in Finder, right-click the app, and select Move to Trash, then empty the Trash. Both methods remove the program from your computer, though some leftover files may remain in hidden folders—this is normal and takes up minimal space.

The process takes under a minute on either system. You do not need special tools or administrator permission for most programs, though some system software may ask for your password before removing.

Key Takeaways

  • Windows users should open Settings > Apps > Apps & Features, select the unwanted program, and click Uninstall.
  • Mac users can drag apps from the Applications folder to Trash, or right-click and select Move to Trash.
  • Some programs leave behind small configuration files after removal, which is harmless and saves almost no space if deleted.
  • A few built-in system apps cannot be removed, but most third-party programs uninstall cleanly in under a minute.

Removing an app on Windows 10 and Windows 11

Click the Start button (Windows logo) in the bottom left corner. Type "Settings" and open the Settings app. Once inside, select Apps from the left menu, then click Apps & Features.

Scroll through the list until you find the program you want to remove. Click on it once to highlight it. A button labeled Uninstall will appear to the right. Click Uninstall, and a confirmation window may pop up asking if you are sure—click Uninstall again. The program will disappear from your computer within seconds.

If the Uninstall button is grayed out, the program is a Windows system app that cannot be removed. This is intentional and protects your computer from breaking. You can hide these apps from your Start menu instead by right-clicking them and selecting Uninstall (which removes the shortcut but not the program itself).

Removing an app on Mac

Open Finder and click Applications in the sidebar on the left. You will see a folder full of all your installed programs. Find the app you want to remove, right-click it, and select Move to Trash. The app disappears from the Applications folder when ready.

To permanently delete it, click the Trash icon in your dock (usually at the bottom right of the screen), then click Empty in the top right corner of the Trash window. Once you empty the Trash, the app is gone for good. If you change your mind before emptying the Trash, you can drag the app back out of the Trash folder into Applications.

Some Mac apps come with an uninstaller program inside their folder. If you open the Applications folder and see a folder with the app's name, open it and look for an Uninstall or Installer file. Double-click it and follow the on-screen steps. This method removes the app and any related files it created.

What happens to your files after you remove an app

Uninstalling a program does not delete your documents, photos, or other personal files. Those stay on your computer unless you specifically delete them yourself. The program itself and its system files are removed, but anything you created with that program remains.

Some programs leave behind small configuration files or settings folders after removal. These take up almost no space—usually less than 1 megabyte. You can delete them manually if you want a completely clean removal, but it is not necessary. On Windows, these hidden files live in a folder called AppData. On Mac, they are usually in a folder called Library in your home directory. Both folders are hidden by default to avoid accidental deletion.

When an app will not uninstall

If you click Uninstall and nothing happens, the program may be running in the background. Close it first: on Windows, right-click the taskbar at the bottom, select Task Manager, find the program in the list, click it, and select End Task. On Mac, open Activity Monitor (search for it in Spotlight), find the program, and click the X button in the top left.

Once the program is closed, try uninstalling again. If it still will not budge, restart your computer and attempt the uninstall when ready after startup, before the program has a chance to run. If the program is a system app that Windows or Mac installed, it cannot be removed—this is by design and protects your operating system from damage.

Using built-in uninstallers

Some programs come with their own uninstaller tool. On Windows, open Control Panel (search for it in the Start menu), click Programs, then Programs and Features. Find the program in the list, click it, and select Uninstall. This method works the same way as the Settings method but is an older route that some people prefer.

On Mac, some programs include an Uninstall process inside their folder in Applications. Open Applications, find the program folder, and look for a file labeled Uninstall or Installer. Double-click it and follow the steps. This removes the app and any related files it created during installation.

Reinstalling an app you removed by mistake

If you uninstall a program and later decide you need it, you can read and install it again. Go to the program's official website or the Microsoft Store (Windows) or Mac App Store (Mac) and read the installer. Run the installer file and follow the on-screen steps to reinstall the program.

Your personal files and documents created with that program are still on your computer—reinstalling the program lets you open and edit them again. Settings and preferences you had before removal will not return, so you may need to set them up again.

Frequently Asked Questions

Does uninstalling an app delete my files made with that program?

No. Uninstalling removes only the program itself and its system files. Any documents, photos, or other files you created with that program stay on your computer. You would have to delete them separately if you want them gone.

Can I uninstall Windows or Mac system apps?

Most built-in system apps cannot be uninstalled—Windows and Mac prevent this to protect your operating system. You can hide them from your Start menu or dock instead. Third-party programs you downloaded always uninstall normally.

What are those leftover folders after I uninstall an app?

Programs sometimes leave behind small configuration or settings folders. These take up almost no space and are harmless. You can delete them manually if you want, but it is not necessary. On Windows, look in AppData; on Mac, look in Library.

Why does an app say it cannot uninstall?

The program is probably running in the background. Close it first using Task Manager (Windows) or Activity Monitor (Mac), then try uninstalling again. If it is a system app, it cannot be removed by design.

Can I reinstall an app after uninstalling it?

Yes. read the installer from the program's website or from the Microsoft Store or Mac App Store, run it, and follow the installation steps. Your files made with that program are still on your computer and will open normally once the program is reinstalled.
