The launch of a big Microsoft Windows 10 update like the Fall Creators Update isn’t the end of a process — it’s really just the beginning. As soon as a major update is released, Microsoft quickly gets to work on improving it by fixing bugs, releasing security patches, and occasionally adding new features.

Here we’ve summarized what you need to know about every Windows 10 update being released to the public. First come updates to the currently shipping version of Windows 10 — version 1709, known as the Fall Creators Update — with the most recent updates on top. (Note that the Fall Creators Update is on a phased rollout, so you may not have received it yet.) Below that are updates to version 1703, known as the Creators Update. For each build, we’ve included the date of its initial release and a link to Microsoft’s announcement about it.

Note: If you're looking for information about Insider Program previews for the next major release of Windows 10, code-named Redstone 4, see "Windows 10 Redstone: A guide to the builds." And if you’re still using an earlier version of Windows, see the Microsoft support site for details about updates to Windows 7, Windows 8.1 and Windows 10 version 1607 / Windows Server 2016.
