Windows 10 is dead, sort of. Official support for the operating system ended on October 14, 2025, but some versions of the operating system are still due to receive support from Microsoft for a few years yet. Now, just weeks out from the broader discontinuation of the OS, bugs are causing headaches for all involved.
As a reminder, Windows 10 users can enjoy the Extended Security Updates (ESU) program via several means, with those living in the European Economic Area (EEA) becoming eligible free of charge. Elsewhere in the world, you’ll need to pay a one-time fee or agree to use Microsoft’s cloud services.
However, even successfully signing up for the ESU or running a version of Windows 10 with guaranteed support baked in won’t keep you safe from upgrade prompts. Those using the Education, Enterprise, and Pro versions of the operating system have been receiving unexpected end-of-life notifications.

Microsoft has already conducted an investigation into the issue. According to the company, this notification bug originated in the KB5066791 update released on October 14. The custodians of the operating system have since deployed a cloud configuration update which should correct this issue.
So, if you’ve joined the ESU on your personal machine and have seen this message, there’s no need to worry. For those in the workplace, make sure to contact your IT Administrator to be on the safe side. All being well, this should amount to little more than incorrect messaging on most systems.
For context, Windows 10 22H2 Pro, Education, and Enterprise, including the Enterprise LTSC 2021 (Long-Term Servicing Channel) and IoT Enterprise LTSC 2021 (Internet of Things), will remain supported until January 12, 2027, and January 13, 2032, respectively.
Hopefully this marks the last spot of bad news for Windows 10, as the operating system undergoes its final sunsets across various versions.
