Thanks for reply.
Well, is not so easy. I know how to find and edit Windows Key in other motherboards, but not on this one
I have tried to find via:
Hex editor
01 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 1d 00 00 00
Total Commander
\w\w\w\w\w-\w\w\w\w\w-\w\w\w\w\w-\w\w\w\w\w-\w\w\w\w\w
but, everything what I can find is: model number, serial number, but no Windows Key
Working dump (from working motherboard) also has a Windows key (checked by RW Ewerything program) and I know Windows key, but I can not find it in bios dump via Hex editor
