keeveek: I haven't updated my WindowsXp since Service Pack 3.
Sue me. That might actually happen. While you can do what you want, you are also responsible for your actions. If your OS is being used as a basis for eg botnets attacks that caused financial loss, it might happen that you get fined. Being sued by the person being harmed itself is probably impossible due legal technicalities (at least here). That line of thought is pretty much how torrent piracy can still be "harvested" legally. They cannot prove that you uploaded something, but they take you in for being responsible that your internet access was being used.
Having an old and "harmful to society" OS can be (hyperbolically) compared to driving a car that runs on kittens and exhausts pure sulphur. Your actions cause harm and costs on the society itself, hence you pay a higher fee than those tree hugging hybrid car driving vegan corneaters. Or if you use that field you have to store battery acid. It will cost you.
Now, currently XP is still "good to use", but if it actually becomes a serious security risk, any user should feel obligated to switch or go off-line. Considering that there are free alternatives available (linux) and Windows is (comparatively) cheap it isn't an unreasonable demand. It might be more difficult for companies that have to switch whole program infrastructures, but those can (IIRC) pay for "extended services" for longer XP usage. (But compare this with what companies had to invest when it came to upgrading their vehicle fleets to accommodated new ecological guidelines or renovating office because of stupid "fire hazards" I think it is manageable).
It wouldn't surprise me, if in the next ten to fifteen years most countries would actually draft some legislation in this regard. As it is my understanding, that the biggest problem with internet crime is outdated security.
