I have tried repeatably to activate Windows. I am getting an error code OXC004F074. What is the problem?
This is a result of patches required on a KMS host running Windows Server 2003 or 2008 not being updated to handle Windows 7 or 8 clients or the time differential between the host and client is more than 4 hours. So if you are activating Volume Licensing, your servers need to be updated. If you are activating against Microsoft's servers, your time settings are incorrect.
