This error is caused by the activation server being aware that the Windows 10 product key may have been used on multiple PCs. When you install the Windows 8.1 or Windows 10 Operating System product a specific number of times, the error code 0xC004C008 normally prompts because the Windows 8.1 or Windows 10 license can only be installed on a single device.
