Can't activate Windows 11 (Error code 0xC004C008)

Error code 0xC004C008 means SL_E_CHPA_MAXIMUM_UNLOCK_EXCEEDED

The activation server reported that the product key has exceeded its unlock limit.

Contact the retailer of the key.

Hi,

The error code 0xC004C008 means that the product key that you are trying to use is already activated on a different device. For us to effectively assist you, can you confirm if you have already activated the product key on another device
before building a new computer? Or was it purchased brand new the same time that you have built the new computer?
