The November 2026 Windows security update will be the last update available for these editions. After this date, devices running these editions will no longer receive monthly security updates containing protections from the latest security threats. We recommend updating eligible devices running Windows 11, version 23H2 to a supported version of Windows 11.
If you have an eligible device, you can check if an update to a supported version of Windows is available by selecting Settings > Windows Update and selecting Check for updates. If your device is ready for the update, you’ll see the option to Download and install.
