The fastest way to uninstall Microsoft Office

On Windows, open Settings, go to Apps > Installed apps, search for "Microsoft Office", and click the three dots next to it, then select Uninstall. Windows will walk you through removing it. On Mac, open Applications, find Microsoft Office apps (Word, Excel, PowerPoint, Outlook), drag each one to Trash, then empty Trash. This removes the programs themselves, but not all the files they leave behind.

The Settings method on Windows is faster than the old Control Panel route and catches most of what you need to remove. However, Office leaves behind preference files, cached data, and activation records in hidden folders. If you want a truly clean removal — especially before selling the computer or switching to a different office suite — you need to clean up those leftover files afterward.

Key Takeaways

  • Windows: Use Settings > Apps > Installed apps, search for Microsoft Office, and click Uninstall; Mac: Drag Office apps to Trash and empty it.
  • Uninstalling the program does not remove preference files, cache, and activation data stored in hidden system folders.
  • On Windows, search your user folder for "Microsoft" and "Office" folders to find and delete remaining files; on Mac, delete Library folders in your home directory.
  • If Office will not uninstall normally, use the Windows Uninstall Troubleshooter or download the Office Removal Tool from Microsoft.
  • Restarting your computer after uninstalling helps clear any remaining processes that might block file deletion.

Removing leftover files on Windows

After uninstalling through Settings, Office leaves behind folders in two main locations. Open File Explorer and navigate to C:\Users\[YourUsername]\AppData. You will see three folders: Local, LocalLow, and Roaming. In each one, look for folders named "Microsoft" or containing "Office" — these hold cached files, templates, and settings. Delete these folders entirely.

Next, check C:\Program Files and C:\Program Files (x86) for any remaining Office folders. If they still exist after uninstalling, delete them. You may also find Office files in C:\ProgramData\Microsoft — this folder is hidden by default. To see it, open File Explorer, click View at the top, and check "Hidden items". Delete any Office-related folders there as well.

If you cannot delete a file because it says it is in use, restart your computer and try again. Windows locks files that are currently running, so a restart clears those locks. After restart, you should be able to delete the remaining folders without errors.

Removing leftover files on Mac

Mac stores Office data in your Library folder, which is hidden by default. Open Finder, click the Go menu at the top, hold Option, and select Library. You will now see the Library folder. Look for folders named "Microsoft", "Office", or "Application Support" and open Application Support to find a "Microsoft" folder inside it. Delete all of these.

Also check the Preferences folder (in the same Library location) for files starting with "com.microsoft". Delete any you find. Finally, check ~/Library/Caches for Microsoft or Office folders and delete those too. The tilde (~) represents your home directory, so you can also type it directly into Finder's search bar.

After deleting these folders, empty your Trash to complete the removal. If Trash will not empty, restart your Mac and try again — this clears any processes still holding onto those files.

When Office will not uninstall normally

Sometimes the standard uninstall fails, usually because a file is locked or corrupted. On Windows, try the Windows Uninstall Troubleshooter, which you can download from Microsoft's support site. Run it and select Microsoft Office from the list — it will attempt to remove Office even if the normal uninstall failed.

If that does not work, Microsoft provides the Office Removal Tool (also called the Support and Recovery Assistant). Download it from Microsoft's website, run it, and let it scan for Office installations. It will remove Office completely, including files the standard uninstall misses. This tool is more aggressive than the normal uninstall and handles stuck or corrupted installations.

On Mac, if dragging to Trash does not work, try restarting in Safe Mode (hold Shift while starting up), then attempt to delete the Office apps again. Safe Mode disables extra processes that might be locking the files. If that still fails, use a third-party uninstaller like AppCleaner, which finds and removes all associated files at once.

Removing Office activation and licensing data

If you are selling your computer or giving it to someone else, you should also remove your Office activation and licensing information. On Windows, open Settings, go to Accounts > Your info, and look for any Microsoft account sign-in. Sign out of your Microsoft account before handing over the computer. This disconnects your Office license from the device.

On Mac, open System Preferences > Internet Accounts and remove any Microsoft account listed there. You can also deactivate Office licenses by opening any remaining Office app (if you have not fully uninstalled yet), going to Account settings, and signing out. This step is important for privacy and prevents the next user from accessing your files or account.

Choosing a replacement office suite

After removing Office, you have several free and paid alternatives. LibreOffice is free, open-source, and handles Word documents, Excel spreadsheets, and PowerPoint presentations well. Google Workspace (Docs, Sheets, Slides) is free with a Google account and works in any web browser. Microsoft 365 is a paid subscription that includes Office apps plus cloud storage and other tools.

If you only need basic document editing, Google Docs is the simplest option — no installation required. If you work with complex spreadsheets or need offline access, LibreOffice or Microsoft 365 are better choices. Test a few options before committing, since switching from Office means learning a new interface and sometimes dealing with formatting differences when opening old Office files.

Frequently Asked Questions

Will uninstalling Office delete my Word documents and Excel files?

No. Uninstalling the Office program does not touch your actual documents. Your files stay in whatever folder you saved them to — usually Documents, Desktop, or OneDrive. Before uninstalling, make sure you know where your files are stored and back them up if you want to keep them.

Can I reinstall Office after completely uninstalling it?

Yes. If you own a Microsoft 365 subscription or a one-time Office license, you can reinstall it anytime by signing into your Microsoft account and downloading it again. If you used a free trial or a work/school copy, reinstalling depends on whether that license is still active.

Do I need to uninstall Office before installing a different version?

It is not strictly required, but it is recommended. Installing a newer version of Office over an older one sometimes causes conflicts or leaves duplicate files. Uninstalling first, then restarting, then installing the new version is the cleanest approach.

What if I see Office files still on my computer after uninstalling?

Those are likely your actual documents (Word files, spreadsheets, etc.), not the Office program itself. The program uninstalls; your files stay. If you want to delete your documents too, you can do that separately, but uninstalling Office does not remove them automatically.

Is it safe to delete the Microsoft folders I found in AppData?

Yes, as long as you have already uninstalled Office through Settings first. Deleting these folders after uninstalling is safe and removes the leftover data. However, do not delete Microsoft folders before uninstalling, as that can break the uninstall process.
