Microsoft has reminded customers today that systems running Home and Pro editions of Windows 11 23H2 have stopped receiving security updates.
Today's announcement follows three previous alerts, when Microsoft asked users to upgrade their devices to the latest available Windows 11 release: the first in August, the second in September, and the last in October.
However, as the company explains on its Windows release health dashboard, Enterprise, Education, and IoT Enterprise editions of Windows 11 23H2 are still under mainstream support for another year, until November 2026.
"Today, November 11, 2025, Windows 11, version 23H2 (Home and Pro editions) has reached end of servicing. The November 2025 monthly security update is the last update available for these editions," Microsoft said in a Tuesday message center update.
"Devices running these editions will no longer receive monthly security and preview updates containing protections from the latest security threats."
Users are now advised to upgrade to Windows 11 25H2 (also known as the Windows 11 2025 Update), which became generally available in September 2025 as an enablement package (eKB) and will reach end of support for consumers in October 2027.
Windows 11 25H2 is now available to all eligible Windows 11 devices for customers who have enabled the "Get the latest updates as soon as they're available" setting.
On an eligible Windows 10 or Windows 11 device, you can check if the update is available by clicking "Check for updates" in the Settings > Windows Update section. If the device is ready to update, you'll see the option to "Download and install Windows 11, version 25H2."
Devices running Windows 11 Home and Pro editions not managed by an IT department will receive the Windows 11 25H2 update automatically; however, they'll still be able to postpone the update or choose the time to restart.
You can find more information about Windows 11 servicing dates on the Windows Lifecycle FAQ page or using the Lifecycle Policy search tool. Microsoft also provides a list of products that will be retired or reach the end of support this year.
