Microsoft Ends Support for Windows Server 2016 and Windows 10 2016 Versions: Upgrade Now


Microsoft will stop all support for Windows Server 2016, Windows 10 Enterprise LTSB 2016, and Windows 10 IoT Enterprise 2016 LTSB soon. No more security patches, bug fixes, or tech help after these dates. Windows 10 versions end October 13, 2026. Windows Server 2016 follows on January 12, 2027. The Microsoft Lifecycle page confirms: “After end of support, receive only Extended Security Updates if enrolled.”

These are LTSC/LTSB editions for stable, long-term use in servers and devices. Support spans 10 years from release. Patching ends with the last Patch Tuesday. Unpatched systems face rising attack risks. Hackers target known flaws in legacy OS.

As of February 26, 2026, no changes to timelines. Microsoft’s Tech Community blog urges migration. “Plan upgrades to Windows Server 2025 or LTSC 2024,”

Staying on old versions breaks compliance. New vulns go unpatched. Enterprises in finance, healthcare, and IoT face audits and breaches. Extended Security Updates (ESU) offer a bridge, but costs rise yearly.
