The Windows Build Tracker is a complete reference for Windows 11 and Windows 10 build numbers, update history, and Insider Preview releases. It includes detailed listings for Canary, Dev, Beta, and Release Preview channels, along with stable GA updates, cumulative KB, and Out-of-band (OOB) releases.
Use the tracker to search builds, compare versions like 24H2 and 25H2, and follow features as they progress from Insider testing to public release. Updated with every new flight and Patch Tuesday, this database gives you a clear view of how Windows is evolving in real time.
Important: I’m in the early stages of building this database, so it’ll take some time for all the updates to appear on this page. If you have ideas for new features or changes for this project, let me know at [email protected].
