Microsoft concluded all support for Windows Vista and Server 2008 as of January 13, 2026. Most customers lost support in January 2020, but Extended Security Updates were available until January 2023 for most users and until January 2024 for Azure customers. Free security updates, non-security updates, and support options are no longer accessible for the retired codebase. Organizations are encouraged to migrate to Azure for additional security updates. Windows Server 2012 will also reach the end of its ESU on October 13, 2026.
