Windows 8 RTM Enterprise Edition – Change Product Key and Activation

Yesterday was the release of Windows 8 RTM for MSDN and TechNet subscribers, After which I downloaded the Enterprise Edition of Windows 8 RTM and Installed on my Lenovo W520. During the installation the setup did not require me to enter a product key but the installation was successful. Upon installation the computer was prompting for Activation. To my surprise i couldn’t find the change product key option under the properties of my computer which Windows 7 had. But to see Windows has assigned itself a product key which fails to activate

No change product key option
