After installing windows 7 and not registering the product I would like to

Please explain proper procedure.

Very simple. Just reboot your system with Windows Vista DVD and reformat
your HD and follow the instructions on screen.

You will need to reformat your HD for sure so always backup your documents,
pictures, music, emails etc.

Hope this helps.
