A Windows launch isn’t the end a process — it’s really just the beginning. As with Windows 10, Microsoft continually works on improving Windows 11 by fixing bugs, releasing security patches, and occasionally adding new features.
In this story we summarize what you need to know about each update released to the public for the most recent version of Windows 11 — currently version 23H2. For each build, we’ve included the date of its release and a link to Microsoft’s announcement about it. The most recent updates appear first.
The easiest way to install updates is via Windows Update. Not sure how? See “How to handle Windows 10 and 11 updates” for full instructions. Note that Windows 11 version 23H2 is being released as a phased rollout and may not be available to you in Windows Update yet.
If you’re still using Windows 10, see “Windows 10: A guide to the updates.” And if you’re looking for information about Insider Program previews for upcoming feature releases of Windows 11, see “Windows 11 Insider Previews: What’s in the latest build?”
