Support for Windows 10 Enterprise LTSB 2016 and Windows 10 IoT Enterprise 2016 LTSB will end on October 13, 2026, while Windows Server 2016 will reach its end of support on January 12, 2027. Organizations using these products will receive one final monthly security update on the specified dates, after which they will not receive security patches, updates, or technical support. The Extended Security Updates (ESU) program allows organizations to purchase coverage for up to three years beyond the end of support, with pricing starting at a specified amount per device for the first year and doubling for each subsequent year. Windows Server 2016's ESU pricing has not been announced, and Microsoft recommends upgrading to newer Long-Term Servicing Channel releases. In the European Economic Area, Windows 10 users can access ESU until October 14, 2026, without payment or cloud account requirements due to advocacy from Euroconsumers.
