In the Windows development ecosystem, build numbers are the true identifier of the operating system's state.
Released to the general public in late October 2023, Build 22631 marked a shift in Microsoft's engineering strategy. While previous "Feature Updates" often required full OS reinstalls or lengthy enablement package processes, 23H2 shares the same core file structure as 22H2. This means that for many users, updating to Build 22631 is a relatively swift process, akin to installing a large cumulative update, rather than a complete system overhaul.
