How to Change the Product Key Number in Windows 8
This tutorial will show you how to enter a new product key number, or change the current product key number to a different key to be used to activate Windows 8 with.
For example, to activate "Windows 8 Enterprise".
You must be signed in as an administrator to be able to do the steps in this tutorial.
You can only use a product key number for the same Windows 8 edition that you currently have installed. For example, you cannot enter or change the product key number in Windows 8 with a Windows 8 Pro product key number, or vice versa.
Once Media Center
is installed (whether turned on or off in Windows Features
), only product key numbers for "Windows 8 Pro with Media Center" will work to activate Windows. Microsoft regards this as a different version of the OS to all intents and purposes. In other words only keys obtained for Windows 8 Media Center will work from then on should you wish to change the key.
