> Microsoft officially ended mainstream support for Windows 10 last month, nudging users to upgrade to Windows 11. While that led to almost [1]an overnight technological revolution in Japan , elsewhere, it has caused a lot of confusion. Certain versions of Windows 10, like Enterprise LTSC -- and those enrolled in the ESU program -- are still scheduled to receive security updates through at least 2027, but [2]they're starting to see out-of-support messages in Settings .

>

> Various users over the past few days reported that they're being subjected to end-of-life warnings in Windows, despite already qualifying for extended security updates through the ESU program. Windows 10 Enterprise LTSC 2021 and âIoT Enterprise are business-oriented editions of the OS, so they're already supported up to 2032, but even they saw these incorrect messages. This widespread bug started to occur after the KB5066791 updates were pushed on October 14, 2025.

>

> Microsoft has already acknowledged this mishap and said, "The message, 'Your version of Windows has reached the end of support, might incorrectly display in the Windows Update Settings page," confirming it as a mistake. The company has already released a cloud config fix that should remove the message, but you need to be connected to the internet for that, and a restart is also required.
