    Sir, How to Enroll into Extended Security Updates in Windows 10? I have my system updated fully but haven't got the "Enroll Now" option in Windows Update in Settings. I have two Windows 10 systems. In one system I got the Enroll Now option and in another, inspite of updating all possible updates from Windows Update, I couldn't get the "Enroll Now" option.

    There is no ESU for this windows release from 10!!! years ago. it died many years ago, only the 2015 LTSB SKU is still supported (for 10 years already) and afaik not elligible for 3 more years.

    Windows 10 19045.xxxx can get 3 more years of (ESU) support by running MAS > TSForge ESU on it.

    Yes, this applies to all LTSB/LTSC branches - they are generally not eligible for any ESU, as they already have the static support period (5 or 10 years) from the start. That's what LTS means.

    The LTSC version of Windows 1809 (LTSC 2019) is not affected. That is an error in the list. They list LTSB 2016 and even IoT LTSC 2021, too, which is also wrong.

    That finally is it for TH1 1507.

    First time's a charm, last time's an honor.
