If you uninstall your current version of Microsoft Office, you should keep your product key on file so you can reinstall it at a later time if you choose to do so.

Microsoft Office 2016

You likely won't need to recover or replace the product key if you purchased Microsoft 2016 online or it's been installed once before. To install Office, go to Microsoft's My Account page and sign in with the Microsoft account tied to the product and click the Install button.

If you'd prefer to install Office using a disk and you need the product key, you can find it on your account page. Under the Account Options, click Install from a disk. On the next screen, click on I have a disk, and then click on the View your product key button to display the install product key.

If you bought the box product at a store and you haven't installed Office 2016 yet, the product key can be found in the packaging.
