Hello, I have just activated Windows 8 using the latest KMS I found on MDL Forums. It worked well, the Windows 8 was activated but... after I checked the Windows Activation in System, I found a label saying: "Your Windows 8 license will expire at: 09/02/2013". So, should I change the product key and reactivate or what? I have Windows 8 Enterprise. Please help me! Thnaks and please response quickly!
