Microsoft to end Windows 11 SE support in 2026
Microsoft will discontinue Windows 11 SE support in October 2026, ending its five-year effort to compete with Chromebooks in educational markets. The operating system launched exclusively for school devices, aiming to prevent customer migration to Google’s Chrome OS platform.
Microsoft confirmed the end date in an updated support document, stating, “Support for Windows 11 SE — including software updates, technical assistance, and security fixes — will end in October 2026.” The company advised educational institutions that while existing hardware will continue functioning, transitioning to standard Windows 11 editions is necessary for ongoing security and support. Devices running Windows 11 SE will remain on version 24H2 permanently, as Microsoft excludes them from receiving the upcoming 25H2 update scheduled for release later this year.
Multiple hardware partners released devices for the platform since its inception. Manufacturers producing Windows 11 SE laptops included:
- Acer
- Asus
- Dell
- Dynabook
- Fujitsu
- HP
- JK-IP
- Lenovo
- Positivo
Microsoft itself introduced the $249 Surface Laptop SE in 2021 as a budget option targeting classroom deployment. This marked another attempt to counter Chrome OS, following the earlier Windows 10 S Mode strategy that restricted applications to the Microsoft Store. That approach encountered user dissatisfaction due to insufficient app availability.
Windows 11 SE similarly promoted Progressive Web Apps (PWAs) over traditional win32 applications. IT administrators faced limitations, required to manually approve win32 software through a tightly controlled exception process managed by Microsoft. Industry analysts at Gartner previously highlighted challenges for Chromebooks, noting they were “losing market share due to their limited customer base and inferior build quality.” Chromebook shipments have consistently declined since 2022, coinciding with a global PC refresh cycle primarily focused on upgrading existing systems to Windows 11 rather than adopting Chrome OS alternatives.
