I have received a replacement computer that has Windows 8.1 pre-installed. The previous computer stopped working and has been destroyed.
I have gone to upgrade it to Windows 8.1 Pro and it accepted the product key but the next day it won't allow me to activate Windows because the product key is in use on another computer.
How do I somehow notify that the previous computer is no longer a computer (it's probably in a thousand pieces by now) and that I am correctly licensed and should be allowed to activate it on this replacement computer.
