**Microsoft Acknowledges Windows 10 "End of Support" Notification Bug for Extended Security Updates Users**
As Microsoft officially ended regular support for Windows 10 in October 2025, many users and organizations have turned to the company’s Extended Security Updates (ESU) program to keep their systems protected. This program, which allows eligible users to continue receiving critical security patches for their Windows 10 installations, has provided a much-needed lifeline for those unable—or unwilling—to upgrade to Windows 11. However, a recent glitch has caused confusion among ESU participants, with some users reporting persistent “end of support” warnings on their devices despite being enrolled in the program.
**The Issue: Confusing Notifications After a Critical Update**
Following the release of the KB5066791 update—Microsoft’s final official security patch for Windows 10 issued on October 14, 2025—many ESU subscribers began noticing a pop-up message. This message informed them that their “version of Windows has reached the end of support,” and that their device was “no longer receiving security updates.” This notification, which normally signals the end of a Windows product’s lifecycle, caused understandable concern among users who had paid or otherwise qualified for continued protection.
Microsoft has since acknowledged the problem on its “Windows 10, version 22H2 known issues and notifications” page. The company clarified that the alarming warning is indeed a bug—not a sign that users have lost access to the promised security updates. The glitch appears to affect a wide range of users, including those running the Pro, Education, and Enterprise editions of Windows 10 22H2, as well as Windows 10 Enterprise LTSC 2021 and Windows 10 IoT Enterprise LTSC 2021, provided they are enrolled in the ESU program with a valid product key.
**Why the Error Occurred and Who Is Affected**
The erroneous notification seems to be directly tied to the installation of the aforementioned KB5066791 update. It is showing up regardless of whether users are individual consumers or part of an organizational IT environment. The core of the issue is a display bug: While the message suggests that the device is no longer protected, in reality, any machine with a valid ESU license continues to receive security updates as intended.
This distinction is important, as many users rely on visible system notifications to verify their update status and compliance, especially in larger organizations where IT security is paramount. The presence of a misleading end-of-support alert could prompt unnecessary concern, confusion, or even misguided attempts to troubleshoot a problem that does not exist.
**Microsoft’s Response and Temporary Workarounds**
In response to the bug, Microsoft has issued a “cloud configuration update” designed to address the notification issue, but this solution is currently optimized for business environments rather than individual home users. For most consumers, the only remedy is patience: Microsoft has promised to correct the error in a future Windows update, which should eliminate the false warning once and for all
