So we have Windows Server 2012 and Windows 8 RTM and want to activate them with our KMS server. For this to be successful we need to update our KMS Service, with is currently servicing out Windows Server 2008 R2 servers and Windows 7 clients.
When we try to activate a Server 2012 server the following error will occur:

If you don’t install this Update then registering a Windows Server 2012 KMS will throw an Error: 0xC004F050 The Software Licensing Service reported that the product key is invalid.
So install the update (Windows6.1-KB2757817-x64.msu) and restart the server!
Just restarting the KMS service (“net stop sppsvc” and “net start sppsvc“) is NOT enough.
Let’s see what is already running:
slmgr.vbs /dlv => The Windows 2008 R2 KMS key.
Uninstall the current KMS key using slmgr.vbs /upk
(We all know this has to be done from an elevated command prompt..)
Now it is time to install the new KMS key.
slmgr.vbs /ipk {YOUR_SERVER_2012_KMS_KEY}
slmgr.vbs /ato to activate the KMS Service
And now we can check our environment to see what we can activate:
slmgr.vbs /dlv => the Windows Server 2012 KMS key.
