The fastest way depends on your operating system

On Windows, you use the Settings app to uninstall Office. On Mac, you drag the Office folder to Trash. Both methods take about five minutes and remove the main programs — Word, Excel, PowerPoint, Outlook, and OneNote — along with their supporting files. The steps differ slightly depending on whether you have Office 2019, Office 2021, Microsoft 365, or an older version, but the principle is the same: find the program in your system's uninstall list and remove it.

Before you start, close all Office programs completely. If Word or Excel is still running in the background, the uninstall will either fail or leave pieces behind. Check your taskbar and system tray to make sure nothing is open.

Key Takeaways

  • On Windows 10 or 11, open Settings, go to Apps, find Microsoft Office, and click Uninstall; on older Windows, use Control Panel instead.
  • On Mac, open Applications, find the Microsoft Office folder, and drag it to Trash, then empty the Trash to complete removal.
  • Uninstalling Office does not delete your documents — they stay on your computer in Word, Excel, or PowerPoint format unless you delete them separately.
  • If the uninstall fails or leaves files behind, you can read the Office Removal Tool from Microsoft to clean up completely.
  • You can reinstall Office later using the same product key or Microsoft account, so uninstalling is not permanent.

How to uninstall Office on Windows 10 or 11

Open the Settings app by pressing the Windows key and typing "Settings", then click the Settings icon. Once it opens, click Apps on the left side, then click Apps & features. Scroll down until you see "Microsoft Office" or the specific version number (such as "Microsoft Office 365" or "Microsoft Office 2021"). Click on it once to highlight it, then click the Uninstall button that appears.

A window will pop up asking you to confirm. Click Yes or Uninstall depending on what the dialog says. Windows will then remove Office from your computer. This usually takes two to five minutes. When it finishes, you may see a message asking you to restart your computer — do that to make sure all files are cleaned up properly.

If you have an older version of Windows (Windows 7 or earlier), use Control Panel instead. Press the Windows key, type "Control Panel", and open it. Click Programs, then Programs and Features, find Microsoft Office in the list, click it, and click Uninstall. The process is the same from there.

How to uninstall Office on Mac

Open Finder and click Applications in the sidebar. Look for a folder named "Microsoft Office" or individual icons for Word, Excel, PowerPoint, and Outlook. If you see a folder, click it once to select it, then press Command+Delete or drag it to the Trash. If you see individual program icons instead, select all of them (click one, hold Shift, and click the last one) and drag them to Trash together.

After moving the programs to Trash, click the Trash icon in your dock, and click Empty to permanently delete the files. This removes Office completely from your Mac. Restart your computer afterward to may support no background processes are still running.

On newer Macs with Apple Silicon chips (M1, M2, M3), the process is identical — just make sure you are looking in Applications, not in a subfolder. If you cannot find the Office folder, use Spotlight search: press Command+Space, type "Word" or "Excel", and see where it shows the program is located.

What happens to your documents when you uninstall

Uninstalling Office does not delete your Word documents, Excel spreadsheets, or PowerPoint presentations. Those files stay on your computer in their original locations — usually in your Documents folder or wherever you saved them. You can still open and read them with other programs, such as Google Docs, LibreOffice, or Apple Pages, even after Office is gone.

If you want to delete your documents as well, you have to do that separately. Find them in File Explorer (Windows) or Finder (Mac), select them, and delete them manually. This is a good time to check if you have documents you no longer need and clean up your storage space.

When uninstall fails or leaves files behind

Sometimes the standard uninstall does not work completely. You might see an error message, or Office might still appear in your programs list even after you clicked Uninstall. This usually happens if a file is locked or if the uninstall process was interrupted.

Microsoft provides a free removal tool for this situation. On Windows, read the Microsoft Support and Recovery Assistant from Microsoft's website, run it, and select the option to uninstall Office. On Mac, read the Office Removal Tool from Microsoft, run it, and follow the prompts. Both tools are designed to find and remove files that the standard uninstall missed.

After using the removal tool, restart your computer and check your programs list again. Office should no longer appear. If it still does, you may have a different version installed (such as Office for Mac 2011, which uses a different uninstall method) — search Microsoft's support site for your specific version number.

Reinstalling Office after uninstalling

If you change your mind later, you can reinstall Office using the same product key or Microsoft account. If you bought a one-time license (Office 2019 or 2021), you will need your product key, which is usually in a confirmation email or on the packaging. If you have a Microsoft 365 subscription, you can sign in with your Microsoft account and read Office again at any time.

Go to account.microsoft.com, sign in, and look for "My Office" or "Install Office" depending on your version. You can install Office on up to five computers at once with a Microsoft 365 subscription, or on one computer with a one-time license. Uninstalling does not use up your installation count, so you can remove and reinstall as many times as you need.

Alternatives if you want to keep some Office programs

You do not have to uninstall all of Office at once. On Windows, you can remove individual programs while keeping others. Open Settings, go to Apps, find Microsoft Office, click it, and look for an Uninstall button or a Modify option. If you see Modify, click it, and you will see a list of programs you can turn on or off. Uncheck the ones you want to remove and keep the rest.

On Mac, you can delete individual program icons from Applications while leaving others in place. For example, you could delete PowerPoint but keep Word and Excel. Just drag the single program icon to Trash. However, if you have the Office folder, deleting individual programs from inside it may cause the remaining programs to stop working properly — in that case, it is safer to remove the entire folder and reinstall only the programs you want to keep.

Frequently Asked Questions

Will uninstalling Office delete my files?

No. Your Word documents, Excel files, and PowerPoint presentations stay on your computer. Uninstalling only removes the programs themselves, not the files you created with them. You can still open those files with other software like Google Docs or LibreOffice.

Can I uninstall Office and then reinstall it later?

Yes. If you have a product key or a Microsoft account with a subscription, you can reinstall Office whenever you want. Uninstalling does not use up your license or delete your account. Just sign in and read it again from account.microsoft.com.

What if the uninstall button is grayed out or does not work?

Close all Office programs completely, including Outlook and OneDrive if they are running. If it still does not work, read the Microsoft Support and Recovery Assistant (Windows) or the Office Removal Tool (Mac) from Microsoft's website. These tools can remove Office when the standard method fails.

Do I need to restart my computer after uninstalling?

It is a good idea to restart after uninstalling, especially on Windows. This ensures that any background processes are stopped and all files are fully removed. You do not have to do it when ready, but do it before you reinstall Office or another program.

Can I uninstall just one Office program like Word or Excel?

On Windows, yes — click Modify instead of Uninstall and uncheck the programs you want to remove. On Mac, you can delete individual program icons, but if they are in a folder together, removing one may break the others. It is safer to remove the whole folder and reinstall only what you need.
