If like me you have installed Windows 8 Enterprise on your machine, you have certainly noticed that you cannot activate Windows because of a DNS error (DNS name does not exist.) if you do not have a KMS server. The error code is 0x8007232B.
To activate Windows Enterprise we will need to change the key of the license.
To activate your account. Take your key on your MSDN account.
Open your Powershell as administrator and type the following commands
> slmgr.vbs /ipk YOUR_KEY> slmgr.vbs /ato
A dialog should now inform you that your Windows license has been activated!
Congratulations your Windows should now be registered.
