Microsoft has announced that Windows 11 SE will reach its end of life in 2026. Initially launched in 2021 for K-8 educational environments, Windows 11 SE was designed as a streamlined, web-first operating system to compete with ChromeOS. It allowed only approved applications for educational purposes and required administrator approval for traditional Windows applications. The last supported version for Windows 11 SE is version 24H2, with no new feature updates planned. Schools using Windows 11 SE devices will need to transition to a supported edition of Windows for ongoing updates and support. Microsoft recommends upgrading to maintain security and support, as it will also phase out support for other products, including Office 2021 and Windows 11 24H2 (Pro and Home), by the same deadline.
