Scenario: Opening and attempting to use Microsoft Office applications immediately after upgrading a PC to Windows 11.
Observed behavior: Microsoft Office displays an 'Unlicensed Product' message and prompts the user to enter a product key, restricting access to editing features.

Solution 1Recommended

Verify License and Account Details

Check if your Office license is active and ensure the Office application is logged into the correct Microsoft account.

Upgrading to Windows 11 can occasionally sign you out of your Microsoft services or cause account syncing issues. Verifying your account details is the fastest way to restore your Office activation.

Sign in to Microsoft Services

Open a web browser, navigate to https://account.microsoft.com/services, and sign in with your Microsoft account credentials.

Confirm your active license

Check the 'Services & subscriptions' page to verify that your Office license is listed and currently active.

Open Office Account settings

Launch an Office app like Word or Excel, click on 'File' in the top-left corner, and select 'Account' from the left-hand menu.

Verify user and switch accounts if necessary

Under 'User Information', ensure the signed-in account matches the one holding your active license. If it does not, click 'Sign out' and then log back in with the correct account.

Multiple Accounts: If you use both a personal and a work/school account on your PC, ensure you are checking the subscription status for the specific account used to purchase Office.

Solution 2

Completely Uninstall and Reinstall Office

Use the Microsoft Support and Recovery Assistant to remove corrupted licensing files and perform a clean installation.

Frequently Asked Questions

Why am I getting an 'Unlicensed Product' error right after upgrading to Windows 11?

Major operating system upgrades like moving to Windows 11 can alter hardware IDs or reset software registries, causing Microsoft Office to lose track of its verified activation status. Re-authenticating your account usually resolves this.

Will uninstalling Office delete my Word documents or Excel spreadsheets?

No. Uninstalling Microsoft Office only removes the application files. Your personal documents, spreadsheets, and presentations saved on your local hard drive or in OneDrive will remain completely untouched and safe.

What should I do if my Microsoft account doesn't show an active Office subscription?

If your license is missing from the 'Services & subscriptions' page, you are likely signed into the wrong Microsoft account. Try signing in with any other email addresses you may have used in the past to purchase or activate Office.

Does the Microsoft Support and Recovery Assistant work on Windows 11?

Yes, the Microsoft Support and Recovery Assistant (SaRA) is fully compatible with Windows 11. It is the recommended tool for automating the uninstallation and troubleshooting of Office products on modern operating systems.
