Dilithium is the 25H1 engineering milestone of Windows as a service taking place since January 2024.

It is codenamed after the fictional material from Star Trek due to negative associations of arsenic[1] (the element after germanium in the periodic table), as it is infamous for its use in poisons due to its toxic properties. This is the second time a fictional element from popular culture was used as the codename for a semester instead of continuing the previous line of chemical elements – the 20H1 semester had previously been codenamed after the Vibranium metal from the Marvel Universe instead of Chromium to prevent confusion with the web browser project.
