Microsoft has announced the end of support for several Windows products launched in 2016, including Windows Server 2016, Windows 10 Enterprise 2016 LTSB, and Windows IoT Enterprise LTSB 2016. Windows Server 2016 has been in the extended support phase since January 2022, with security updates available until January 12, 2027. Windows 10 Enterprise 2016 LTSB and Windows IoT Enterprise LTSB 2016 will reach the end of their extended support on October 13, 2026. Microsoft offers the Extended Security Updates (ESU) program for these products, allowing critical security updates for a fee, with costs for Windows 10 Enterprise 2016 LTSB set to increase annually per device. ESU will also be available for Windows Server 2016, but pricing details are not yet released. Windows IoT Enterprise LTSB 2016 will receive extended support through hardware manufacturers, with terms and costs varying by supplier. Microsoft emphasizes that using unsupported software increases risks and that migrating to a newer version of Windows is the only long-term solution.
