Note: If Office came pre-installed on your new device, see Activate Office that's pre-installed on a new Windows 10 device.

Activate Office that's pre-installed on a new Windows 10 device

Shows the "Let's get started" screen that indicates an Office 365 trial is included with this device

If this screen appears, Office is installed as an Office 365 Home trial

You'll see this screen if you sign in to Office that was pre-installed on a new device but don't have an Office product associated with your account.

To use Office on your new device, you can activate Office as a 1-month trial of Office 365 Home. You can also buy Office, add Office to an existing Office 365 subscription, or enter a product key from a new product key card. If you have an older copy of Office, you can install that instead.

A digital Office product key is transmitted to your PC, so you won't need or receive a printed product key. You activate Office by selecting the Activate Office button. Be sure to activate Office as soon possible. The offer will expire 180 days after you activate Windows.

Troubleshoot activation errors

If Office can't activate, it eventually becomes unlicensed and all editing features of Office are disabled. Office can become unlicensed for a number of reasons. For example, if your Office 365 subscription expires, you must renew your subscription to restore all features of Office. If Office was pre-installed on your new PC, you must start an Office 365 Home trial or buy Office to continue using Office.

A subscription notice appears when I open an Office 365 application

You get the Office error "The products we found in your account can't be used to activate <app>"
