I formated it and now I always get error code 0xC004C003. and i cannot change the product key, i tried to contant HP and they told me to contact microsoft about this issue. I'm wondering why is that happened this is the second time happened to me. I searched the forums and tried all the solutions mentioned by Microsoft team and no one of them worked with me!!!. I have one more question is this will happen on every format?!?!.
