Solution 1Recommended

Check Microsoft Account and Reinstall Office

Verify if your Office license is digitally linked to your Microsoft account and reinstall the software directly from your subscriptions page.

Modern preinstalled Office licenses are often digital entitlements bound to the first Microsoft account used on the device. Signing out or experiencing a major system update can sometimes cause the apps to lose track of this activation.

Sign in to Microsoft Account

Go to the official Microsoft Account website and log in using the email address you originally used on the laptop.

Navigate to Services & subscriptions

Click on the 'Services & subscriptions' tab at the top of the dashboard to view all licenses linked to your account.

Uninstall the Unlicensed Version

If you see your Office entitlement listed, open your laptop's Settings, go to Apps, and uninstall the current unlicensed version of Microsoft Office.

Reinstall Office

Return to the 'Services & subscriptions' page and click the 'Install' button next to your Office product to download and reactivate a fresh copy.

Check Multiple Accounts: If you do not see a subscription, try logging in with other email addresses you may own, as the license is strictly tied to the account used during the initial setup.

Solution 2

Contact Manufacturer or Microsoft Support

If no license is found in your accounts, seek official support to identify the original license type provided with your laptop.

Frequently Asked Questions

Why did my preinstalled Office suddenly lose its license?

This can happen due to major Windows updates, hardware changes (like replacing a motherboard), or accidentally signing out of the linked Microsoft account. Additionally, if your laptop only came with a 1-year Microsoft 365 Personal subscription, the license may have simply expired.

How can I find the product key for my preinstalled Office?

Modern preinstalled Office versions typically do not come with a physical 25-character product key. Instead, they use a Digital Product Key that is either injected into the device's motherboard or digitally linked to the first Microsoft account used to activate the software.

Does resetting my laptop remove my Office license?

A factory reset will remove the Office applications from your hard drive, but it does not destroy your license. If the license is linked to your Microsoft account, you can simply reinstall and reactivate it by signing back into the Services & subscriptions page online.

Can I edit my files for free if I cannot recover my Microsoft license?

Yes. You can use the free web-based version of Microsoft Office in your browser, or you can download a free desktop alternative like WPS Office to continue editing and saving your documents locally without an active Microsoft subscription.
