What is a Product Key?
A Windows 8.1 Pro key is the serial you are asked to enter when you install Windows 8.1 Pro edition. You are granted to access the full functions only when the software or its remote server determines your product key is genuine. Since you can download the setup files online, a Windows 8.1 Pro product key is all you need. (incase you can't find the download resource, we provide additional download service with the product key)
