Windows 10 loT Enterprise LTSc 21H1has reached the end of support

Hi Maverick Zou,

I see from your screenshots that you're running Windows 10 IoT Enterprise LTSC 2021 (version 21H2, build 19044.6456) on a device like a MAXHUB Room-B2, and the Windows Update screen is displaying an end-of-support warning despite the lifecycle table indicating extended support through 2032 for this specific edition. Your understanding is mostly correct.

For standard consumer editions of Windows 10 (like Home, Pro, Education, and Enterprise non-LTSC), mainstream support indeed ended on October 14, 2025, meaning no more free security updates, feature updates, or technical assistance without enrolling in paid Extended Security Updates (ESU). However, Windows 10 IoT Enterprise LTSC 2021 operates under a different Fixed Lifecycle Policy tailored for embedded and IoT scenarios, where stability and long-term support are prioritized over frequent changes.

According to Microsoft's official lifecycle documentation, this edition became available on November 16, 2021, with mainstream support (which includes feature updates, though LTSC rarely gets them) ending on January 12, 2027. After that, it enters the extended support phase, where Microsoft continues to provide security patches for critical vulnerabilities until January 13, 2032—no new features, just security fixes to keep the system protected. This extended timeline is exclusive to the IoT variant; the standard Windows 10 Enterprise LTSC 2021 ends all support on January 12, 2027, without an extended phase.

The "end of support" message you're seeing in Windows Update is likely a bug or false flag that's been reported affecting some LTSC installations, even though support is ongoing. This could be due to the "Some settings are managed by your organization" note, which suggests group policies or MDM (Mobile Device Management) configurations might be interfering with the update UI—LTSC editions are often deployed in managed environments where updates are controlled via tools like WSUS (Windows Server Update Services) rather than standard Windows Update. Recent discussions confirm that IoT LTSC 2021 systems are still eligible for updates post-October 2025, and Microsoft has acknowledged similar false EOL notifications in non-consumer editions.

To confirm ongoing support on your device, you can check for updates manually (even if the message persists).

If the warning bothers you or blocks checks, consider reviewing your device's management settings (e.g., via gpedit.msc under Computer Configuration > Administrative Templates > Windows Components > Windows Update) or contacting your organization's IT admin, as IoT LTSC is typically licensed for specialized use cases.
