After receiving their final monthly security update, they will no longer get security patches, bug fixes, non-security updates, technical support, or updated online documentation.
| Product | End-of-Support Date |
|---|---|
| Windows 10 Enterprise LTSB 2016 | October 13, 2026 |
| Windows 10 IoT Enterprise 2016 LTSB | October 13, 2026 |
| Windows Server 2016 | January 12, 2027 |
End Support for Legacy Windows Versions
For defenders, the key issue is the accumulation of risk after patching ends.
Systems that remain on these versions after the final Patch Tuesday will increasingly fall out of compliance and become easier targets as new vulnerabilities are discovered and attackers focus on unpatched populations.
Microsoft notes that “LTSB” is the older name for today’s “LTSC” channel, designed for special-purpose devices; the naming shows up differently across documentation, but the lifecycle dates are what matter.
Microsoft’s primary guidance is to upgrade rather than treat extended coverage as a long-term plan. For servers, the recommended destination is Windows Server 2025.
| Current Product | Recommended Upgrade Options |
|---|---|
| Windows Server 2016 | Windows Server 2025 |
| Windows 10 Enterprise LTSB 2016 | Windows 11 Enterprise LTSC 2024 (hardware permitting) or Windows 10 Enterprise LTSC 2021 |
| Windows 10 IoT Enterprise 2016 LTSB | Windows 11 IoT Enterprise LTSC 2024 (hardware permitting) or Windows 10 IoT Enterprise LTSC 2021 |
If timelines do not allow a full migration, Microsoft points to the Extended Security Updates (ESU) program as a temporary bridge for up to three years after the end-of-support date.
ESU provides only “critical” and “important” security updates (per Microsoft’s severity ratings) and offers limited technical support focused on ESU activation, update installation, and issues caused by updates.
ESU does not add features, quality improvements, or design changes, and it does not restore full product support.
For Windows 10 Enterprise 2016 LTSB, Microsoft said ESU will be sold via Volume Licensing or a Cloud Solution Provider in Q2 2026.
Priced at USD per device for year one, discounted to per device for systems managed with Intune or Windows Autopatch.
Microsoft also cautioned that ESU pricing doubles each consecutive year (up to three years) and is cumulative, meaning enrolling in year two requires paying year one as well. For Windows 10 IoT Enterprise 2016 LTSB, ESU is available only through IoT OEMs.
