Buy Windows 8 Pro Product Key
To use KMS, you need to have a KMS host available on your local network. Computers that activate with a KMS host need to have a specific product key. This key is sometimes referred to as the KMS client key, but it is formally known as a Microsoft Generic Volume License Key (GVLK). Computers that are running volume licensing editions of Windows Server and Windows client are, by default, KMS clients with no extra configuration needed as the relevant GVLK is already there.

If you want to activate Windows without a KMS host available and outside of a volume-activation scenario (for example, you're trying to activate a retail version of Windows client), these keys will not work. You will need to use another method of activating Windows, such as using a MAK, or purchasing a retail license. Get help to find your Windows product key and learn about genuine versions of Windows.
If you are converting a computer from a KMS host, MAK, or retail edition of Windows to a KMS client, install the applicable product key (GVLK) from the list below. To install a client product key, open an administrative command prompt on the client, and run the following command and then press Enter:

But what happens if someone buys a Windows 8 PRO laptop, and wants to downgrade to Windows 7 Pro.I've heard a few different confusing and conflicting things. I've heard that if you have a computer with Windows 8 Pro and install Windows 7 Pro on it, you just use the Windows 7 Pro DVD install the OS, and type in the Windows 8 Pro product key, and bam you're activated. But maybe I misunderstood this. I've heard some people say you need to use a Windows 7 volume key. But also, now Windows 8 laptops are shipping without a product key sticker (COA).So basically, how do I activate Win 7 Pro on a computer that shipped with Windows 8 Pro, without spending any more money, and without having a Windows 7 volume license?I've heard that I need to get install media from the manufacturer? Why can't I install Windows 7 from generic media?
I just don't quite understand Microsofts activation process.I know Windows computes some kind of system description and sends it to Microsoft, so if too much hardware changes, Microsoft will think it's a new system and require you reactive windows. Does Microsoft's activation server take a look at that hardware description and say "ohhh, that guy already activated Windows 8 Pro, so we can activate Windows 7 Pro" So am I supposed to punch in ANY Windows 7 key? or am I supposed to punch in a Windows 8 key?
To sum it up, grab a copy of Win7 Pro, install it and when you don't have a product key to enter call the Activation support phone number. On the laptop, look under the battery for the Win8 Pro key - a lot of manufacturers hide it there now. If it's not there, the person on the phone should be able to help you through the process. 041b061a72
