I’ve heard, but not bothered to verify, that Windows jumped from 8 to 10 because there were so many vestigial references to “9,” i.e. Windows 95/98 that they couldn’t clear up.

Ward never revealed how it was made, saying merely that it contained ‘up to 21 organic polymers and copolymers, and small quantities of ceramics’.
