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.

Microsoft is facing a significant security challenge due to hundreds of millions of unsupported PCs still in use, particularly those running Windows 10. Nearly a billion users have not transitioned to Windows 11, with about 500 million on PCs that cannot upgrade. Microsoft has released its final Patch Tuesday updates for 2025, addressing 56 vulnerabilities, including three zero-days. Windows 10 users not enrolled in the extended security updates (ESU) program will no longer receive automatic updates, with November’s Patch Tuesday marking the first serious fixes not extended to them. Users can enroll in the ESU program at no cost, allowing access to recent updates, with no deadline for enrollment until October 2026. Delaying enrollment increases vulnerability to attacks.

Dell's Chief Operating Officer, Jeffrey Clarke, reported a 10% to 12% lag in the migration from Windows 10 to Windows 11 compared to previous adoption rates. Approximately 500 million PCs are incompatible with Windows 11 due to its stringent system requirements. Dell has seen an increase in PC sales for 2025 but anticipates flat sales in 2026 due to rising component costs and supply chain issues. The slow uptake of Windows 11 may lead consumers to retain their Windows 10 machines or consider alternatives like Linux or macOS. Microsoft is providing extended support for Windows 10 until October 2026, allowing users more time to decide on upgrades. The future pace of migration to Windows 11 may be influenced by Microsoft's integration of AI functionalities.

Microsoft's Windows 10 reached its end-of-life on October 14, leading to the introduction of Windows 11. Dell's COO, Jeffrey Clarke, indicated that the transition to Windows 11 is slower than expected, with a 10-12 point lag compared to the previous OS transition. Approximately 500 million PCs are unable to upgrade to Windows 11, and Microsoft has implemented Extended Security Updates (ESU) to support these devices temporarily. Dell noted that around 500 million additional PCs could transition to Windows 11 without hardware upgrades. Despite this, Dell reported record Q3 results of billion, primarily driven by AI servers and infrastructure rather than PC sales, which have shown mid-to-high single-digit growth in a flat overall market.
