Microsoft Windows Server 2012 and 2012 R2 Extended Security Updates available

Microsoft Windows Server 2012 and 2012 R2 Extended Support ended on October 10, 2023. Microsoft Windows Server 2012 and 2012 R2 Extended Security Updates are now available.


What is the Extended Security Update (ESU) program?

The Extended Security Update (ESU) program is a last resort option for customers who need to run certain legacy Microsoft products past the end of support. It includes critical and/or important security updates for a maximum of three years after the product’s End of Extended Support date.


Are Extended Security Updates (ESUs) available through CSP?

Yes. 1-year ESUs are now available through the Microsoft Cloud Solution Provider (CSP) program.


How will ESUs be distributed?

  • In Azure, ESUs are automatically applied.
  • In on-premises and hosted environments, there are two options to get ESUs:
  1. ESUs enabled by Azure Arc, where you can enroll your machines in Windows Server 2012/R2 or SQL Server 2012 ESUs via the Azure portal, connect through Azure Arc, and pay for them as an Azure billed service. You pay a monthly fee for these ESUs. There are no keys needed; the new Azure subscription performs all the authentication and replaces the need for acquisition, deployment, and management of keys. Additionally, an inventory view will show the Extended Security Update coverage of all Windows and SQL Server machines enabled by Azure Arc.
  2. Get ESUs through Windows Update, Windows Server Update Service, and the Microsoft Update Catalog.
