The fastest way to delete a program
Open Settings (the gear icon in your Start menu), then go to Apps > Apps & features. Scroll through the list until you find the program you want to remove, click it once, and a button labeled Uninstall will appear. Click that button and follow the prompts — most programs uninstall in under a minute.
This method removes the program files and usually cleans up the shortcuts from your Start menu and desktop. It is the safest way because Windows handles the removal process instead of you manually deleting folders.
If you cannot find the program in that list, it may be a built-in Windows app (like Mail or Photos). Those uninstall the same way, but the button says Uninstall for some and Remove for others. Either one removes the app from your computer.
Key Takeaways
- Settings > Apps > Apps & features is the main place to remove programs on Windows 10, and it works for almost everything you have installed.
- Clicking a program name shows an Uninstall button that removes the program and its files in one step.
- Some programs leave behind small files called registry entries even after uninstall, but these do not take up meaningful space or slow your computer.
- If a program refuses to uninstall, restarting your computer and trying again usually solves the problem.
- Deleting a program folder by hand from your hard drive can leave broken pieces behind and is not recommended.
What happens when you uninstall a program
When you click Uninstall, Windows removes the program's main folder (usually located in C:\Program Files or C:\Program Files (x86)) and deletes the shortcuts from your menus. The program no longer appears in your Start menu, and it no longer runs when you start your computer.
The uninstall process also removes most of the program's settings and data files. If you reinstall the same program later, it will start fresh with default settings rather than remembering your old preferences.
Some programs leave behind small configuration files in a hidden folder called the Windows Registry. These leftover pieces take up almost no space and do not affect your computer's speed. If you want to remove them completely, you would need a specialized tool, but most people never notice they are there.
When a program will not uninstall
Sometimes you click Uninstall and nothing happens, or you get an error message. The most common reason is that the program is still running in the background. Close the program completely, then try uninstalling again.
If that does not work, restart your computer and uninstall when ready after it boots up, before the program has a chance to start. Many programs load automatically when Windows starts, so uninstalling right after a restart catches them before they can block the removal.
A few programs require you to uninstall them using their own uninstaller instead of Windows Settings. Look on the program's folder (in C:\Program Files) for a file called Uninstall.exe or check the program's own menu for an uninstall option. If you still cannot remove it, the program may be protected by administrator settings on your computer — contact whoever manages your computer's security settings.
Programs that come with Windows 10
Windows 10 includes built-in apps like Mail, Calendar, Photos, and Groove Music. You can uninstall most of these the same way you uninstall other programs — go to Settings > Apps > Apps & features, find the app, and click Uninstall or Remove.
A few core Windows programs (like Settings itself, or Cortana) cannot be uninstalled because Windows needs them to run. If you do not use an app but want to keep it, you can hide it from your Start menu instead: right-click the app in your Start menu and choose Unpin from Start.
If you uninstall a built-in app and change your mind later, you can reinstall it from the Microsoft Store (the app with the blue shopping bag icon in your Start menu). Search for the app by name and click Get to read it again for free.
Freeing up space by removing programs
Large programs like video editing software, games, or design tools can take up several gigabytes of space on your hard drive. Uninstalling programs you no longer use is one of the fastest ways to free up that space.
To see which programs are using the most space, go to Settings > System > Storage. Click Apps & features in the Storage window, and Windows will show you a list of installed programs sorted by size. Programs at the top of the list are taking up the most space.
After you uninstall a program, the freed-up space becomes available when ready — you do not need to restart your computer or run a cleanup tool. If you want to see the change reflected in your Storage window, refresh the page by pressing F5.
Removing programs without using Settings
If Settings is not working or you prefer an older method, you can uninstall programs through the Control Panel. Open Control Panel (search for it in the Start menu), click Programs, then Programs and Features. You will see the same list of installed programs. Click any program and an Uninstall button appears at the top of the list.
This method works identically to the Settings approach — it is just a different way to reach the same uninstall process. Most people find Settings easier because it is faster to open, but Control Panel works just as well.
Do not delete a program by dragging its folder to the Recycle Bin. This leaves behind registry entries and configuration files that can cause problems later. Always use either Settings or Control Panel to uninstall, because they handle the cleanup automatically.
Frequently Asked Questions
Will uninstalling a program slow down my computer?
No. Uninstalling programs that you do not use can actually make your computer slightly faster because it frees up disk space and removes programs that might be running in the background. The more space your hard drive has available, the faster Windows can work.
Can I uninstall Windows 10 itself?
No, you cannot uninstall Windows 10 from within Windows 10. If you want to remove it, you would need to install a different operating system using installation media, which is a technical process. For most people, uninstalling Windows is not necessary — you would only do this if you were replacing your computer's entire operating system.
What if I uninstall a program by mistake?
You can reinstall it by downloading it again from the program's website or from the Microsoft Store if it is a Windows app. Your files and documents are not affected by uninstalling a program — only the program itself is removed. If the program had saved data (like game progress or document settings), that data may be lost, but your personal files remain safe.
Do I need to restart my computer after uninstalling a program?
Usually not. Most programs uninstall cleanly without requiring a restart. A few older programs may ask you to restart, but modern software almost never does. If you are not sure whether the uninstall worked, restart anyway — it will not hurt and will may support the program is completely gone.
