Hackers would have more fun with XP if they open sourced it so no thanks, I think they should just let it die,no OS can remain forever especially one full of security holes.
you have to say why did microsoft release windows xp which must of had lots of security problems right on release which even after 12 years microsoft has not fixed them all. I think part of the problem was releasing windows xp without a antivirus and firewall for starters.
