They never did when I used such discs back in the days, and why would DELL be allowed to distribute software making such a thing possible? Of course you could argue that he has manipulated the program on the disc but as far as I know that has not been proven and he is claiming he did not.
They answer your question on the Dell disks, which basically boils down to the convenience of customers unable to reactivate properly for whatever reason, who merely get nag screens. May only have applied to some Dell customer groups and some Windows versions and I'm not about to dig out my old Dell XP reinstallation disk to find out! Presumably they trust that [certain groups of] Dell customers are not buying new computers with bundled Windows versions with the intention of reusing the software on unlicensed older machines, and make enough from selling the OEM licence not to care about the low level of piracy they anticipated as a result.
