Uninstall Old Office via Windows Settings
The most direct method to remove older Office applications using your computer's built-in application manager.
This standard uninstallation method works for most users and cleanly removes the programs associated with the older version of Office.
Click the Start menu and select the gear icon to open Settings, then navigate to 'Apps' and click on 'Apps & features' (or 'Installed apps' in Windows 11).
Scroll through the list of installed applications or use the search bar to find 'Microsoft Office', 'Microsoft Office Professional Plus', or the specific older version installed (e.g., Office 2016 or 2019).
Click on the Microsoft Office application from the list, select 'Uninstall', and confirm your choice. Follow the on-screen prompts to complete the removal process.
Once the uninstallation wizard finishes, restart your computer to ensure all registry entries and background services are completely cleared.
Use the Official Microsoft Uninstall Support Tool
Use this official utility if the standard uninstallation fails or leaves behind residual files that block Microsoft 365.

Frequently Asked Questions
Will uninstalling my old Office version delete my documents?
No, uninstalling Microsoft Office only removes the application files (like Word and Excel). Your personal documents, spreadsheets, and presentations will remain completely safe on your hard drive and will open normally once you install Microsoft 365.
Can I keep my old Office version and install Microsoft 365 at the same time?
While it is technically possible to have multiple versions of Office installed in some scenarios, Microsoft highly recommends uninstalling older versions to prevent severe software conflicts, especially with Outlook profiles and default file associations.
What should I do if the uninstallation gets stuck or freezes?
If the standard Windows uninstallation process freezes, cancel the process and restart your computer. Then, use the official Microsoft Support and Recovery Assistant (SaRA) uninstall tool, which is designed to force-remove stubborn Office files safely.
Do I need my old product key to uninstall Office?
You do not need your product key to uninstall Office from your computer. However, you should ensure you have your Microsoft account login information or the Microsoft 365 subscription details ready to activate your new installation.
