Why the VALID Windows 8 Pro product key is rejected when activating Windows?
Why a VALID product key from an Official Box of the Full Windows 8 Pro 64bit DVD installed on a new hard disk, is rejected as INVALID when Activating Windows at the very end of this installation process?
The PC is a All-in-one Hewlett-Packard Touch Screen of 15 months.
After the single hard drive crashed (it was running Windows 7 Home upgraded to 7 Ultimate), a new replacement hard disk has been fit in and checked.
The installation has gone through without any problem. Thanks.
