If your new Windows 10 PC came with Office re-installed, one of two Let's Get Started screens will appear when you open an Office app. These screens indicate whether Office was paid for with your PC, or whether you received a free 1-month trial to Office 365 Home.
Start Office to see which version is installed
To start Office, press the Start button on the lower-left corner of your screen, type Word 2016, and then select the Word 2016 icon. One of the following two Let's Get Started screens will appear:
If you see Try, Buy, Activate
Office is installed as an Office 365 Home trial
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 product key card. If you have an older copy of Office, you can install that instead.
Office is installed as a one-year subscription or one-time purchase
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 Activatebutton and associating your purchase or offer with a Microsoft account.
