Current status as of October 10, 2023
As of October 10, 2023, Home and Pro editions of Windows 11, version 21H2 have reached end of servicing. The October 2023 security update, released on October 10, 2023, is the last update available for these editions. After this date, devices running these editions will no longer receive monthly security and preview updates containing protections from the latest security threats. Enterprise, Education, IoT Enterprise, and Enterprise multi-session editions for this version will reach end of servicing on October 8, 2024 and will receive security updates until then.
To help keep you protected and productive, Windows Update will automatically initiate a feature update for Windows 11 consumer devices and non-managed business devices that are at, or within several months of reaching, end of servicing. This keeps your device supported and receiving monthly updates that are critical to security and ecosystem health. For these devices, you will be able to choose a convenient time for your device to restart and complete the update.
As always, we recommend that you update your devices to the latest version of Windows 11. For detailed information, see the Windows 11, version 21H2 end of servicing (Home & Pro) lifecycle page. For information about servicing timelines and lifecycle, see Windows 11 release information, Lifecycle FAQ - Windows, and Microsoft Lifecycle Policy search tool.
