Solution 1Recommended

Activate Office with an Existing Product Key

Use this solution if you have already purchased a Microsoft Office license or have a product key included with your PC.

Windows 11 and Microsoft Office are separate products. Many new PCs come with a pre-installed 30-day trial of Microsoft 365. If you own a valid product key, you must link it to your Microsoft account to activate the software.

1
Locate your product key

Find the 25-character product key from your physical receipt, email confirmation, or the Office card included in your computer's packaging.

2
Visit the setup page

Open a web browser and navigate to https://setup.office.com.

3
Sign in and redeem

Sign in with your Microsoft account, enter your 25-character product key, and follow the on-screen instructions to redeem your license.

4
Refresh your Office app

Open Microsoft Word on your PC, sign in with the same Microsoft account, and the trial expired message will disappear.

Activate Office with an Existing Product Key
Account Linking: Once your key is redeemed, the license is permanently tied to your Microsoft account, meaning you will not need the physical key again for reinstallations.

Frequently Asked Questions

Does Windows 11 come with a free version of Microsoft Office?

No, Windows 11 and Microsoft Office are separate products. While a new Windows 11 PC often comes with a pre-installed 30-day trial of Microsoft 365, a paid license or subscription is required to continue editing documents after the trial ends.

Where can I find my Microsoft Office product key if I purchased one?

If you purchased a physical copy from a retailer, the 25-character product key is usually printed on a card inside the box. If you purchased it digitally, check your email receipt or look at the purchase history within your Microsoft account.

Can I still view my documents if my Office trial expires?

Yes, once your Microsoft Office trial expires, the applications enter a 'read-only' mode. You can still open and view your existing documents or print them, but you will not be able to make edits or create new files until you activate a license or switch to a free alternative like WPS Office.

How do I stop Office from asking for activation every time I start my PC?

To stop the activation prompts completely, you must either activate the software using a valid product key, sign in with a Microsoft account that holds an active subscription, or uninstall the expired trial software from your Windows 11 'Installed apps' settings.
