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. 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 22H2 is being released as a phased rollout and may not be available to you in Windows Update yet.
