Did you download Windows 8 Enterprise using your MSDN or TechNet subscription for testing in your lab? As the full-featured "business edition" of Windows 8, the Enterprise SKU defaults to using corporate Volume License activation on a business network. On a business network, this process provides a simplified end-user activation experience, because Windows 8 Enterprise automatically determines which servers to activate against using DNS without you needing to manage individual activation keys for each PC. To learn more about the Windows 8 Volume License activation process on a business network and the new Active Directory-based activation process, click here.
But, what if I'm testing Windows 8 Enterprise in an isolated lab environment?
This VL activation process works well in a business environment to simplify and automate the overall activation experience, but if you're testing Windows 8 Enterprise in an isolated environment, then you'll encounter an error during the activation process and activation will not successfully complete. This is because your Windows 8 Enterprise PC cannot find the appropriate DNS records to determine how to automatically activate. But, there's an alternative! In your TechNet and/or MSDN subscription portal, you have the ability to claim a "Multiple Activation Key" (MAK) for activating Windows 8 Enterprise by clicking the "Product Keys" button. The MAK is an alternative Product Key that doesn't require the same corporate VL activation process on a business network.
Great! I've got my MAK - What do I do now?
To enter your MAK on Windows 8 Enterprise and successfully activate, you can complete one of the following steps:
Enter your MAK in the "Product Key" field shown above, click the "Activate" button and you should be good to go!
