This is for the CD and booklet new and sealed, there is no product key included, you will need this to activate the OS. When you are prompted to activate the operating system, choose "Activate by telephone". The numbers provided are still valid. At the prompts for product type choose "other". You will then provide the installation ID and they will read you back the activation ID. Please ensure that the computer you intend to install this software on has a Windows XP Professional license sticker attached. I am providing these to replace lost or damaged discs. We ship these via first class shipping in a 9x7x1 bubble mailer and protected by cardboard. Thank you for your interest!
