All genuine Microsoft Office software is issued a product key. This key is entered during the installation process to activate your software. If you purchase the software in a store, the product key is provided with the software. If your version of Office is pre-installed on a new computer, it is listed on a sticker on the bottom of your computer. If you do not have your product key and need to re-install your Office suite, you can use free software to find your product key.
