Your only option is to keep track of your device installs and the corresponding Office versions. The bottom line is there is no way to obtain the full Product Key using commands or third-party software unless you use Office 2010 or earlier. The image below applies to Microsoft Office 2013 and newer, even though they are pushing their 365 subscriptions. Unfortunately, Microsoft made changes beginning with Office 2013, where only the last five digits of the product key get stored on your PC. Each one has specific methods for installation and reinstallation, as well as how the product key gets stored and used. There are four types of Microsoft Office software: Retail, Subscription, Volume, and OEM. It’s difficult to find, so you might be panicking trying to remember the lost activation code.


One example is LibreOffice, which is a fully-fledged, suite, complete with alternatives to Word, Excel, PowerPoint and more. The good news is that you can get a perfectly good free alternative which is still compatible with Microsoft Office document formats. Each license only usually covers one machine.

Old physical copies are likely to be available on eBay and similar sites, but make sure it’s not already been activated.

Microsoft has never made Office available as a completely free product, so expect to pay if you want access to its capabilities.
