Microsoft releases October security updates for Windows 11
Microsoft has released mandatory October updates for Windows 11 versions 23H2, 24H2, 25H2 and 26H2.
The updates include security patches for hundreds of vulnerabilities found in previous months, as well as bug fixes and new features.
The 25H2 and 26H2 updates are based on the same release as 24H2, so they include the same changes.
File Explorer changes include new options for previewing downloaded files and remembering whether Home sections are expanded or collapsed.
The update also adds Emoji 17.0 and a Tips widget, alongside improvements to desktop backgrounds and Bluetooth reliability.
These changes matter because the release addresses security flaws while making some Windows features work differently or more reliably.
Users can install the update through Windows Update or download it from the Microsoft Update Catalog.
