Windows Server 2012 R2 Extended Security Updates

Windows Server R2 extended support has officially come to an end.

On October 10th, 2023 extended support for Window Server 2012 R2 officially came to an end.  Although most IT departments have been able to upgrade or migrate away from these servers, there may still be mission critical applications running on Windows Server 2012R2 that do not have an update available yet. For those instances Microsoft is able to offer the Extended Security Updates program.  What is the Extended Security Updates Program (ESU)?  It is a last resort for customers who need to run legacy Microsoft products past the end of support date.

If you must run a legacy server past the end of support date you have two options.  Migrate the affected server to an Azure Virtual Machine which includes Extended Security Updates, or purchase and Extended Security Updates subscription from Microsoft.

If you choose to subscribe to ESU for servers still running on premise you have several deployment options for the updates with varying requirements for each, depending on if you choose Azure Arc to deploy the updates.

If you are running Microsoft SQL 2012 which has also reached end of support, you can leverage its own Extended Security Updates. Contact your account manager or anyone with Keller Schroeder’s Datacenter Team for more information on Extended Security Updates (ESU) or migration paths from legacy operating systems.
