Dilithium is the 25H1 engineering milestone of Windows as a service that took place between late January 2024 through August 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 notably poisonous. 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.

Like Copper and Gallium, development fluently transitioned into the next milestone, Selenium, around build 27691 and did not enter a stabilization phase usually associated with the creation of release branches.
