    Hi @cj.ackermann ,

    You won't be able to activate Windows 10 using Windows 11 product key, it will only work the other way (Activate Windows 11 with Windows 10 key).

    It may be possible to obtain a downgrade product key, I'd ask the reseller about downgrade rights.

    Hi @cj.ackermann

    I suppose Windows activation will not work in reverse order. You can use the Windows 10 key to activate the Windows 11 .
