Restoring XP w/o recovery disks

Hi all could someone help me I got sucked into upgrading my sons pc to vista by a free vista upgrade ...and as most of you know this is the most unstable p.o.s operating system ever!.. I did not make recovery disks when I upgraded from XP to vista. Is there any way I can revert back to XP w/o these disks?please?
Thanks in advance and Happy New Year!!

No, you can't just down grade. Your going to have to format and reinstall XP. Vista is completely different then XP. There is a guide on how to install XP right here:

That is if you have an XP install disk?
