Many enterprises still run legacy line-of-business applications, SQL Server instances, or file services on this operating system. However, Windows Server 2008 reached End of Extended Support on January 14, 2020 (for 2008) and January 10, 2023 (for 2008 R2). This means no more free security patches from Microsoft.
