How to Find the Microsoft Product Key

Microsoft produces a variety of software products. As a measure of ensuring that customers receive an authentic Microsoft product, a 25-character product key is required to complete the installation process. If you were able to use the Microsoft software when you purchased your computer, but are now prompted to type the product key, this is because it is a trial version of Microsoft software pre-installed by your computer manufacturer. In this example, you have to purchase a product key for the full version of Microsoft Office suite.

• 1

  Look for the product key sticker on the software CD case or other packaging.

• 2

• 3

  Purchase a perpetual product key from a retail store or from the Microsoft website.
