Windows ESU – Does enrollment end on 13 Oct 2026 or does the program end on that date?

Hi,

I would like clarification regarding the Windows 10 Extended Security Updates (ESU) timeline.

When Microsoft states that ESU is available until 13 October 2026, does this mean:

13 October 2026 is the last date customers can sign up/enroll in the ESU programme? OR

13 October 2026 is the official end date of the ESU programme itself (i.e., security updates stop on that date)?

In other words, if a customer enrolls close to October 2026, will updates only be provided until 13 October 2026, or does enrollment extend coverage beyond that date?

I would appreciate clarification based on Microsoft’s official lifecycle policy documentation.

Thank you.

    13 October 2026 is the end of the ESU coverage period, not a date after which coverage continues.

    From the Windows lifecycle ESU FAQ, Windows 10 ESU has the following dates:

    • End of support for Windows 10: 14 October 2025
    • ESU Year 1 end date: 13 October 2026
    • ESU Year 2 end date: 12 October 2027
    • ESU Year 3 end date: 10 October 2028

    These dates are described as “ESU End Date Year 1/2/3”, meaning they are the last dates through which Critical and Important security updates are provided for that ESU year.

    For the consumer ESU program specifically (Windows 10 Home/Pro, etc.), Microsoft states:

    • “You can enroll in ESU any time until the program ends on October 13, 2026.”
    • “If you enroll after the ESU program launches, you will receive any previous updates as well as any future updates.”

    Putting this together:

    • For consumer ESU (Home/Pro/Pro Education/Workstation):
      • 13 October 2026 is both the last day to enroll and the last day security updates are provided under that consumer ESU program.
      • Enrolling close to that date only provides updates up to 13 October 2026; coverage does not extend beyond that date.
    • For commercial ESU (Enterprise/Education/Pro in commercial use):
      • ESU is structured in three annual years after end of support, with end dates in 2026, 2027, and 2028 as listed in the lifecycle FAQ.
      • Each ESU year’s end date is the end of update coverage for that year; enrollment does not extend coverage beyond the published ESU end dates.

    In all cases, ESU does not extend the product lifecycle; it only provides Critical/Important security updates up to the published ESU end dates.

    Dear DARIUS WU JUNYE,

    Thank you for your question about Windows ESU.

    1. Based on Microsoft’s official documentation and lifecycle policy, October 13, 2026, is the official end date of the consumer ESU program itself. So if a customer enrolls close to October 2026, the security updates will only be provided until 13 October 2026.
    2. Additionally, after October 14, 2025, any refunds would follow our policy for digital purchases for your country. For complete details on how to return eligible products, see our Returns and Refunds page. *And if you enrolled in ESU at no additional cost by backing up your PC settings, you were not charged for ESU, so there would not be any refunds.

    *For more information, please check out Windows 10 Consumer Extended Security Updates (ESU).
