Thanks for the reply you all. cluberti,cant type in the key cause its "banned" by MS. I googled the key and i found it on like 1 billion sites,so its no wounder i cant use that one. I was about to change the key anyway cause it will be used as an work machine,so all the software on it must be legit. The key i would like to use is not a "stolen" key,its from my work and its payed for. The 7 digit number i typed was not taken from my comp,i only wrote something to illustrate the difference One says oem and the other says 640. Has anyone uses the sysprep tool to change the installed settings? Ill try it today and give you all some feedback.
