How to Activate Microsoft Word Without a Product Key
Question details
The user needs to activate Microsoft Word but cannot locate their original 25-character product key.

- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Reinstalling or reactivating Office on a new or existing device without having the physical or digital product key on hand.
- Observed behavior
- The user needs a method to authenticate and activate their Word application using alternative credentials, such as a linked Microsoft account.
Ensure you have an active internet connection and know the email address and password for the Microsoft account you originally used to purchase or register Office.
Activate Word Using Your Microsoft Account
Modern Office licenses are tied to your Microsoft account, eliminating the need for a physical product key.
If you are using a current supported version of Microsoft Office or Microsoft 365, your digital license is linked directly to your Microsoft account. You do not need the original product key for reactivation.
Launch the Microsoft Word application on your computer.
Click on 'File' in the top-left corner of the ribbon menu, then select 'Account' from the bottom-left sidebar.
Click the 'Sign In' button and enter the credentials for the Microsoft account associated with your Office purchase or subscription.

Locate Product Keys for Older Perpetual Licenses
If you are using an older version of Office (such as Office 2010 or 2013), you may still need the original key.
Skip the Activation Hassle with WPS Office
If you cannot recover your Microsoft account or product key, switch to WPS Office. It provides a highly compatible, free suite for all your document needs without complex activation barriers.
- 1. Download the Installer: Visit the official WPS Office website and click the free download button.
- 2. Install WPS Office: Run the downloaded installer file and follow the straightforward on-screen instructions.
- 3. Open Your Word Documents: Launch WPS Writer and directly open your existing .docx files to continue working seamlessly.

Frequently Asked Questions
Can I activate Word if I bought it pre-installed on my PC?
Yes. For many pre-installed versions of Office, the digital license is embedded in the device's motherboard or automatically linked to the first Microsoft account you signed in with. Simply signing in with that account will activate Word.
Where do I go to check which Microsoft account has my Office license?
You can visit the Microsoft Account Services and Subscriptions page (account.microsoft.com/services) via a web browser. Log in with any email addresses you might have used, and your active Office licenses will be listed there.
What if I completely lost access to my Microsoft account and the product key?
If you cannot recover your account via Microsoft's account recovery form and have no physical proof of purchase, you may need to purchase a new license. Alternatively, you can download a free office suite like WPS Office to continue editing your documents.
