How to Find the Product Key for Microsoft Office Word 2007 After It Is Installed

1. If you obtained your copy of Microsoft Office Word 2007 via CD or DVD, check the sticker on the packaging. The product key will be printed there.
2. Check the Certificate of Authenticity, which verifies that your copy of the software is legal. You will have received a Certificate of Authenticity with your copy of the software, either with your CD or DVD, or in an email from Microsoft if you purchased your software online.
3. If you purchased the software online, check the confirmation email message sent to you by Microsoft.
4. If you cannot locate the product key that came with the software, you can purchase a 'perpetual' product key, which you will either find inside a new Product Key Card available in stores or online from Office Online with the full download of Microsoft Office.
