When you try to change the product key in Windows 8 or in Windows Server 2012, you cannot find a "Change product key" link in the System item in Control Panel.
For example, you want to convert a default setup product key to a Multiple Activation Key (MAK) on a computer that is running Windows 8. However, you cannot find an element in the UI that lets you change the product key.
