I was unable to access windows 11 after an update had ruined my SSD so i did a fresh install on the same SSD with USB drive and upon re-installing i have been presented with this error and i have tried troubleshooting in many ways, i only have one device as the reset has erased my previous setup stopping me from being able to re-activate.
I have bought TWO official codes and neither of them work... below it displays both product ID and product KEY and i have no idea what to do now.. windows 11 has been causing me so many issues. User's image

    Hello, AidanGeoghegan-7838.

    Error 0xC004C008 indicates that "The key is being used on another PC". Try following these steps:

    Run the Command Prompt as an Administrator and run the commands in order

    slmgr.vbs /ipk <ProductKey>

    slmgr.vbs /ato

    where <ProductKey> is a 25-digit product code.

    After executing the commands, restart the PC and check for activation after 5-7 minutes. If there is an activation error, then post a screenshot of the command window here

    slmgr.vbs /dlv

    P.S. Please do not post the full product keys here!
