Thanks for the help It's a repair CD for me and my friends. My friends lacks the skills to install XP, and maintaning it... So I make personal CD's for each of them. And I plan to have it fully update with hotfixes, and their drivers added. So I easily can re-install their PC. As for the key, I use the one they give me. How they got it, I don't know and don't care. My goal is to have a easy install and a secure and updated PC.
