The Two Ways to Remove a Program

Windows 10 gives you two built-in ways to delete a program: through Settings (the newer method) or through the Control Panel (the older method that still works). Both remove the program files and free up disk space. Settings is simpler if you know the program name. Control Panel gives you a longer list and shows file sizes, which helps if you are trying to free up space and want to see which programs take the most room.

A third option exists: some programs come with their own uninstaller that you can run directly. You will find this in the program's folder, usually under C:\Program Files or C:\Program Files (x86). But the Settings or Control Panel method works for almost everything and is safer because Windows handles the removal instead of relying on the program's own uninstaller.

Key Takeaways

  • Open Settings, go to Apps, then Apps & Features, find the program, and click Uninstall to remove it using the newer method.
  • The Control Panel method (Programs and Features) shows file sizes so you can see which programs use the most disk space before you delete them.
  • Some programs require administrator permission to uninstall, and Windows will ask for your password if you are not logged in as an administrator.
  • Restarting your computer after uninstalling a program is sometimes necessary, especially if the program was running when you removed it.
  • Built-in Windows programs like Notepad and Calculator cannot be uninstalled through Settings, but you can hide them or remove optional features instead.

Uninstalling Through Settings (The Faster Method)

Open the Start menu and type Settings, then click the Settings app. Click Apps in the left sidebar. On the next screen, click Apps & Features. You will see a list of all your installed programs in alphabetical order.

Find the program you want to remove by scrolling or by typing its name in the search box at the top. Click the program name once to select it. A button labeled Uninstall will appear. Click it. Windows will ask you to confirm, and the uninstaller will run. Some programs show a dialog box with options during removal; most just remove themselves silently. When it finishes, the program disappears from the list.

If you do not see an Uninstall button, the program is either built into Windows (like Notepad) or requires administrator permission. For built-in programs, look for a button labeled Remove instead. For programs that need administrator permission, Windows will prompt you to enter your password or confirm the action.

Uninstalling Through Control Panel (The Detailed Method)

Open the Start menu and type Control Panel, then click the Control Panel app. Click Programs, then Programs and Features. You will see a list of all installed programs with their size and install date shown in columns.

Click the program you want to remove to select it. An Uninstall button appears above the list. Click it. The uninstaller runs the same way as in Settings. Control Panel is useful when you want to see how much disk space each program uses before deciding what to delete. You can click the Size column header to sort programs by size, largest first.

Control Panel also shows programs that Settings sometimes hides, particularly older software or system utilities. If you cannot find a program in Settings, try Control Panel instead.

What Happens to Your Files When You Uninstall

When you uninstall a program, Windows removes the program files themselves and the entries in your system that tell Windows how to run it. This frees up disk space. However, the uninstaller usually leaves behind any files you created with that program — documents, photos, videos, or settings you saved.

For example, if you uninstall Microsoft Word, the Word program disappears, but any Word documents you wrote stay on your computer. If you uninstall a game, the game itself is gone, but saved game files usually remain. This is intentional: Windows assumes you want to keep your work even if you no longer want the program.

If you want to delete those leftover files too, you can search for them after uninstalling. But be careful — some programs store settings and data in hidden folders that are hard to find. If you are certain you will never need the files again, you can delete them manually, but it is not necessary.

When You Cannot Uninstall a Program

If the Uninstall button is grayed out or missing, the program is usually one of three things: a built-in Windows program, a program that requires administrator permission, or a program installed for all users on the computer.

For built-in programs like Notepad, Calculator, or Photos, you cannot uninstall them through the normal method. Instead, go to Settings, click Apps, then Apps & Features, scroll down, and click Optional Features. Find the program in that list and click Uninstall. Some built-in programs cannot be removed at all, but you can hide them from your Start menu by right-clicking them and selecting Uninstall (which hides rather than removes them).

If a program requires administrator permission, Windows will show a dialog asking for your password or confirmation. Enter your password and the uninstall will proceed. If you are not an administrator on your computer, you will not be able to uninstall programs that require admin rights — you will need to ask the person who set up your computer.

Restarting After Uninstalling

Most programs uninstall without requiring a restart. However, some programs — especially older software, system utilities, or programs that were running when you uninstalled them — may ask you to restart your computer to complete the removal. If you see a message asking to restart, click Restart Now or Restart Later depending on whether you need to save work.

If you do not restart when asked, the program may not fully remove itself, or some of its files may remain on your disk. Restarting is usually quick and ensures the uninstall is complete. If you chose Restart Later, remember to restart your computer before you use it again.

Freeing Up Disk Space by Removing Large Programs

If your computer is running low on disk space, uninstalling programs is one way to free it up. Use Control Panel to see which programs take the most space, then decide which ones you no longer need. Games, video editing software, and design programs often use several gigabytes each.

Before you uninstall, make sure you have copies of any files you created with that program. If you uninstall a photo editor, for example, save your edited photos in a different format first. Once the program is gone, you will not be able to open files in its native format unless you reinstall it.

After uninstalling, you can also run the Disk Cleanup tool to remove temporary files and other clutter. Open the Start menu, type Disk Cleanup, and click the app. Select your C: drive and click OK. Check the boxes for the types of files you want to remove, then click Delete Files.

Frequently Asked Questions

Can I undo an uninstall if I change my mind?

No, Windows does not have an undo for uninstalls. However, you can reinstall the program if you have the installer file or if you can read it again from the publisher's website. If the program came with your computer, check the manufacturer's support page. Some programs also keep backups of your settings, so reinstalling may restore your preferences.

What if a program will not uninstall no matter what I try?

Restart your computer in Safe Mode, which loads Windows with minimal programs running. Then try uninstalling again. If that does not work, the program may be corrupted or locked by another process. You can also try uninstalling from Control Panel instead of Settings, or search the program's website for a dedicated uninstaller tool they provide.

Do I need to uninstall a program before installing a newer version?

Not always. Many programs can install over themselves, updating to the new version automatically. However, uninstalling first ensures a clean install with no leftover old files that might cause conflicts. Check the program's installation instructions to see whether it recommends uninstalling the old version first.

Will uninstalling a program slow down my computer?

Uninstalling programs does not slow down your computer directly. However, removing large programs frees up disk space, which can help your computer run faster if your drive was nearly full. The main benefit is freeing space, not improving speed.

Can I uninstall Windows 10 itself?

No, you cannot uninstall Windows 10 through Settings or Control Panel. If you want to remove Windows 10 and install a different operating system, you need to use a bootable installation disk or USB drive for the new system. This is an advanced process that erases your entire drive, so back up your files first.
