- Scenario
- Reinstalling productivity software and recovering the product license after performing a factory reset on a laptop.
- Observed behavior
- The laptop has been reset to factory settings, removing the installed Microsoft Office suite, and the user needs to restore it without purchasing a new license.
Ensure you have access to the Microsoft account credentials originally used to purchase or activate your Office subscription, as this is the easiest way to verify your license for a free reinstallation.
Reinstall Office from Your Microsoft Account
If your Office license was previously linked to your Microsoft account, you can easily download and reinstall the suite without paying again.
Digital purchases and modern Office product keys are typically tied to your Microsoft account upon activation. This digital linkage allows you to reinstall your software across device resets effortlessly.
Open a web browser and navigate to https://account.microsoft.com/services. Sign in using the Microsoft account associated with your Office Home and Business purchase.
Scroll through your 'Services & subscriptions' list until you find your specific Microsoft Office product.
Click the 'Install' button next to your Office product and follow the on-screen prompts to download the setup file to your reset laptop.

Reactivate a Preinstalled (OEM) Office License
If your laptop came with Office preinstalled, the license is usually tied to the device hardware or the original Microsoft account used during the initial setup.
Activate Using a Physical Product Key
If your copy of Office was purchased via a physical retail box and never linked to an online account, you will need the original 25-character product key to reinstall it.

Frequently Asked Questions
Can I transfer my Office license to a new laptop instead of a reset one?
Yes, if you have a retail version of Office Home and Business linked to your Microsoft account, you can install it on a new computer. However, you must first ensure it is uninstalled or deactivated from the old device to comply with the one-device licensing terms.
What if I forgot which Microsoft account is linked to my Office purchase?
You can try signing into account.microsoft.com/services with all your known email addresses. If you still cannot locate the subscription, contacting Microsoft Support with your original purchase details or product key is the best course of action.
Do I need the product key if my Office is already linked to my Microsoft account?
No. Once a physical or digital product key is redeemed and linked to your Microsoft account, the 25-character key is no longer needed for installation. You only need to sign in to your Microsoft account online to manage and reinstall your Office software.
