Hi, Would someone who knows more about these things tell me if I am on the right track, please. I have a laptop (Toshiba L300) with vista and it has a 2.1 slic. I have extracted the installed OEM certificate that matches the slic. My understanding is that the slic 2.1 and the existing vista certificate will bo OK for windows 7. Is this correct? All i need is the matching SKU OEM for Win 7. Is this correct too? Thanks guys.
