Windows Server 2016 reaches the end of extended support on January 12, 2027. If you cannot retire or upgrade every server by then, Extended Security Updates (ESUs) provide Critical and Important security updates through January 2030, but not new features or non-security fixes. Microsoft now makes the Azure Arc option generally available: it connects on-premises and other cloud servers to Azure so that you can license and enroll them centrally. This is a temporary security measure while you complete an upgrade or migration plan, not a replacement for it.Source : 4sysops
