Now in this article, we will list all the possible ways that you can find Office product key online or on your computer.
Generally, after software installation on computer, product key is saved in registry file. Office 2016 product key is also stored in system registry after installation. Just because it is written in binary format, human cannot read it directly.

As is known from Microsoft, a product key isn’t provided if when you buy or download Office online, the Microsoft account you used during the first Office installation will be linked to the product and will be needed if you need to reinstall.
Therefore, if you have Office 2016 installations associated with your Microsoft account, you can login into your Microsoft account, see the installations and get the key on the My Account page.
Step 1: On My Account page, you can view partial product key codes for Office installations.
Navigate to Account Options > Install from a disc > I have a disc, and click View your product key button. Then product key for the installation is displayed.

If Office 2016 is preinstalled on your computer, probably its product key is printed on the Certificate of Authenticity sticker on computer, especially common for Windows 7 PCs. The one in registry and key-viewer application is a red herring. So if it came with a CD, look for the sticker on the card to find Office 2016 product key.
