    Activating a new device with Win11 Pro key


    Good day,A few years ago I bought a Windows PC without activated Windows which I activated thanks to a key I received from the company BCS IT GmbH DE. I still have a key that I received through Email and used on my previous device. But not a long ago, I just bought a new device and tried to activate Windows with my key, after deleting Windows on previous device. But I got an error that I tried to use an invalid Windows Key. What can I do to pass my key to my new device, when I have already deleted everything from the old one and used slmgr /upk and slmgr /cpky commands in old Windows?

    :)
