Windows Server 2012 and 2012 R2 reaching end of support
 

Windows Server 2012 and Windows Server 2012 R2 will end on October 10, 2023. After this date, these products will no longer receive security updates, non-security updates, bug fixes, technical support, or online technical content updates. If you cannot upgrade to the next version, you will need to use Extended Security Updates (ESUs) for up to three years. ESUs are available for free in Azure or need to be purchased for on-premises deployments.
