The fastest way depends on your operating system
Deleting an app from your computer works differently on Windows and Mac, and the method you use matters because some leave behind files that clutter your system. On Windows, you'll use the Settings menu or Control Panel. On Mac, you'll drag the app to Trash or use an uninstaller. The key difference is that Windows apps often scatter files across your system, while Mac apps tend to live in one folder.
Before you delete anything, close the app completely — don't just minimize it. If the app is running in the background, the deletion may fail or leave fragments behind. Check your taskbar or menu bar to confirm it's fully shut down.
Key Takeaways
- On Windows 10 and 11, go to Settings > Apps > Apps & Features, find the app, and click Uninstall.
- On Mac, drag the app from Applications to Trash, then empty Trash to complete the deletion.
- Some apps come with their own uninstaller program — check the app's folder before deleting manually.
- Deleting an app does not remove your account or saved files unless you specifically delete them separately.
- If an app won't delete, it may be running in the background or protected by administrator settings.
How to delete an app on Windows 10 or 11
Open Settings by pressing the Windows key and typing "Settings," then click the Settings app. Once it opens, click Apps in the left sidebar, then Apps & Features. Scroll through the list until you find the app you want to remove. Click it once to highlight it, then click the Uninstall button that appears.
A dialog box will pop up asking you to confirm. Click Uninstall again. Windows will remove the app and most of its files. The process usually takes a few seconds to a minute. When it's done, the app will no longer appear in your Start menu or search results.
If you don't see an Uninstall button, the app may be built into Windows and cannot be removed through this method. Some system apps can be disabled instead — right-click the app in the list and look for a Disable option.
How to delete an app on Mac
Open Finder and click Applications in the sidebar on the left. Scroll through the list until you find the app you want to delete. Click it once to select it, then either drag it to the Trash icon in your dock, or right-click it and select Move to Trash.
The app will disappear from your Applications folder when ready, but it's not fully deleted until you empty the Trash. To do that, right-click the Trash icon in your dock and select Empty Trash. Once you do, the app and its files are permanently removed.
Some Mac apps come with their own uninstaller program. Before you drag an app to Trash, open its folder in Applications and look for a file called "Uninstall [App Name]" or similar. If you find one, double-click it and follow the prompts — this method removes the app more thoroughly.
What happens to your files and accounts when you delete an app
Deleting an app does not automatically delete your account with that service or any files you created in it. For example, if you delete Spotify, your account and playlists remain on Spotify's servers. If you delete a photo editor, the photos you edited stay on your computer unless you delete them separately.
However, some apps store settings and cached data in hidden folders on your system. When you uninstall the app through Settings or Applications, these files usually stay behind. They take up very little space, but if you want to remove them completely, you'll need to find and delete them manually — this is more advanced and not necessary for most users.
When an app won't delete
If you click Uninstall and nothing happens, the app is probably still running. Close it completely, check your taskbar and background processes, and try again. On Windows, you can open Task Manager (press Ctrl + Shift + Esc) and look for the app in the list. If it's there, click it and select End Task.
On Mac, open Activity Monitor (search for it in Spotlight), find the app in the list, click it, and click the X button in the top left corner. Then try deleting the app again.
If the app still won't delete, it may be protected by administrator settings. On Windows, right-click the Uninstall button and select Run as Administrator. On Mac, you may need to enter your password when prompted. If you still can't delete it, the app may be a system file that your computer needs, and you should leave it alone.
Apps that come with built-in uninstallers
Some programs, especially larger ones like Adobe Creative Suite or Microsoft Office, come with their own uninstaller tool. This tool removes the app more thoroughly than the standard method because it knows exactly where all the app's files are scattered across your system.
To find the uninstaller, look in the app's folder. On Windows, go to Control Panel > Programs > Programs and Features, find the app, and look for an "Uninstall" or "Repair" option. On Mac, check the Applications folder for a folder with the app's name — inside it, you may find an Uninstaller. If you find one, run it before trying to delete the app manually.
Cleaning up after deletion
After you delete an app, you may notice it still appears in your search results or in a list of recently used apps. This is normal and usually clears itself within a few hours or after you restart your computer. If it persists, restart your system and the reference should disappear.
On Windows, you can also clear the search index manually. Go to Settings > Search > Searching Windows, scroll down, and click Advanced. Look for an option to rebuild the index. On Mac, this happens automatically and you don't need to do anything.
Frequently Asked Questions
Does deleting an app free up storage space?
Yes, but the amount varies. Small apps take up a few megabytes, while large ones like video editors or games can take up several gigabytes. If your computer is running low on storage, deleting unused apps is one of the fastest ways to reclaim space. You can check how much space an app uses before deleting it — on Windows, go to Settings > System > Storage and click an app to see its size.
Can I reinstall an app after I delete it?
Yes. If you delete an app from the Microsoft Store or Mac App Store, you can reinstall it from the store without paying again (if it was free) or by logging into your account (if you purchased it). For apps you downloaded from the internet, you'll need to read the installer again from the developer's website.
What if I delete an app by accident?
On Windows, check your Recycle Bin — deleted files go there first and can be restored. Right-click the app and select Restore. On Mac, check your Trash folder and drag the app back to Applications. If you've already emptied Trash or Recycle Bin, you'll need to reinstall the app from its original source.
Will deleting an app remove viruses or malware?
If the app itself is malicious, deleting it removes that threat. However, malware can hide in multiple places on your system, not just in one app. If you suspect your computer has malware, run a full antivirus scan with a trusted security program rather than relying on deleting individual apps.
