I bought a new laptop and ran magic jellybean and got the Product ID and CD Key off the pre-installed windows 7 Home Premium 64- bit from Toshiba. I have a copy of WIndows 7 Home Premium disc and installed it to get rid of all the crap that comes on the laptop. After installing Windows 7, the product ID is the same on both, but the key number errors out upon trying to activate it. Is there certain files I need to pull off the laptop using the factory system to add to or overwrite on the other disc to Toshiba OEM it and make the CD key to work? Thank you.
