This is why i will always save a copy of my windows xp enterprise edition cd. It's xp, which is still decent enough, and it doesn't require any activation, as opposed to the home/pro-editions.
In case apocalypse happens (ehum, my ISP goes down for 24h) i know i can still get a computer up and running without problem if i have to.
Is that legal? One of the reasons MPAA/RIAA are pissing everyone off and have lost all credibility is that they have helped write and pass many copyright related laws that make even the most natural things to do illegal. They are so out of touch with reality.
