Microsoft’s extended security updates (ESU) program for Windows 10 has encountered a minor hiccup, leaving some users perplexed by erroneous “end of support” notifications. Despite having signed up for the program, individuals may find their PCs displaying a message indicating that support has concluded. Rest assured, this is not a reflection of any misstep on your part; rather, it stems from a display bug that Microsoft is actively addressing.
In a recent update to its known issues page, Microsoft confirmed that users may see the misleading message after installing the KB5066791 update, which was released on October 14, 2025. This update marks the final official security patch for Windows 10, and the glitch affects various editions, including Windows 10 22H2 Pro, Education, and Enterprise, all of which are enrolled in the ESU program and configured with a valid ESU product key. Additionally, Windows 10 Enterprise LTSC 2021 and Windows 10 IoT Enterprise LTSC 2021 are also experiencing this issue.
Fortunately, Microsoft has clarified that this glitch is merely a visual error. Machines equipped with a legitimate ESU license will continue to receive the promised security updates. For businesses, Microsoft has rolled out a “cloud configuration update” as a temporary solution. However, individual users may need to await a forthcoming Windows update that will rectify the issue.
Despite the cessation of official support for Windows 10 in October, many users and organizations remain on the platform. The ESU program offers a pathway to extend support for an additional year. Users can qualify for the ESU through several methods, including a flat fee of or by redeeming 1,000 Microsoft Rewards points, which can be accumulated through various activities, such as using Microsoft Bing for searches.
For those seeking a cost-effective option, utilizing the built-in Windows Backup tool to sync settings to the cloud is the most economical route. Regardless of the method chosen, Windows should recognize your enrollment and ensure your device is included for future updates.
How to check for the bug
If you suspect that your Windows 10 PC has been affected by this bug, you can easily verify it. Navigate to Settings, select Update & Security, and then click on Windows Update. The full notification will read: “Your version of Windows has reached the end of support. Your device is no longer receiving security updates.” To confirm your eligibility for updates, look for a message stating: “Your PC is enrolled to get extended security updates.” If you see this confirmation, there’s no need for concern regarding the misleading error message; you remain on track to receive the necessary security updates.
