I'm trying to reinstall win8 Pro w/ Media Center on an older Dell C2D system for a friend. She has no discs as she got it from her brother for x-mas a little while back and she's unable to get them as he lives out of state. I used a program to extract the keys, but it seems that the media center add-on has overridden the pro key and it wont let me install windows. I noticed it gave me an internet explorer key that was different from the win8 key, but it rejected that too. Is there a way to extract the original win8 pro key? I couldn't seem to find anything with google.
