Windows Server 2016 will end extended support on January 12, 2027. Organizations unable to upgrade can utilize Extended Security Updates (ESUs) through Azure Arc, which are now generally available. These updates provide Critical and Important security patches until January 2030 but do not include new features or non-security fixes. Azure Arc allows for centralized management of on-premises and cloud servers, offering a pay-as-you-go model for ESUs. This solution is intended as a temporary measure while organizations plan their upgrades or migrations. The option is crucial for maintaining security in environments still reliant on Windows Server 2016.
