-There are some scenarios in which you may be eligible to receive Extended Security Updates patches at no additional cost. Two of these scenarios supported by Azure Arc are (1) [Dev/Test (Visual Studio)](/azure/devtest/offer/overview-what-is-devtest-offer-visual-studio) and (2) [Disaster Recovery (Entitled benefit DR instances from Software Assurance](https://www.microsoft.com/en-us/licensing/licensing-programs/software-assurance-by-benefits) or subscription only). Both of these scenarios require the customer is already using Windows Server 2012/R2 ESUs enabled by Azure Arc for billable, production machines.

These tags allow you to link your Azure machines to existing licenses that are already configured with payable cores without needing to create any new licenses or add additional cores to your free machines.
 
 **Example:**
-- You have 8 Windows Server 2012 R2 Standard instances, each with 8 physical cores. Six of these Windows Server 2012 R2 Standard machines are for production, and 2 of these Windows Server 2012 R2 Standard machines are eligible for free ESUs through the Visual Studio Dev Test subscription.

Six of these Windows Server 2012 R2 Standard machines are for production, and 2 of these Windows Server 2012 R2 Standard machines are eligible for free ESUs because the operating system was licensed through a Visual Studio Dev Test subscription.
     - You should first provision and activate a regular ESU License for Windows Server 2012/R2 that's Standard edition and has 48 physical cores to cover the 6 production machines. You should link this regular, production ESU license to your 6 production servers.
     - Next, you should reuse this existing license, don't add any more cores or provision a separate license, and link this license to your 2 non-production Windows Server 2012 R2 standard machines. You should tag the ESU license and the 2 non-production Windows Server 2012 R2 Standard machines with Name: "ESU Usage" and Value: "WS2012 VISUAL STUDIO DEV TEST".
     - This will result in an ESU license for 48 cores, and you'll be billed for those 48 cores. You won't be charged for the additional 16 cores of the dev test servers that you added to this license, as long as the ESU license and the dev test server resources are tagged appropriately.

 In all cases, you're required to attest to conformance with SA or SPLA. There is no exception for these requirements. Software Assurance or an equivalent Server Subscription is required for you to purchase Extended Security Updates on-premises and in hosted environments. You will be able to purchase Extended Security Updates from Enterprise Agreement (EA), Enterprise Subscription Agreement (EAS), a Server & Cloud Enrollment (SCE), and Enrollment for Education Solutions (EES). On Azure, you do not need Software Assurance to get free Extended Security Updates, but Software Assurance or Server Subscription is required to take advantage of the Azure Hybrid Benefit.
 
+### Visual Studio subscription benefit for dev/test scenarios
+
+Visual Studio subscriptions allow developers to get product keys for Windows Server at no additional cost to help them develop and test their software. If a Windows Server 2012 server's operating system is licensed through a product key obtained from a Visual Studio subscription, you can also get extended security updates for these servers at no additional cost. To configure ESU licenses for these servers using Azure Arc, you must have at least one server with paid ESU usage. You can't create an ESU license where all associated servers are entitled to the Visual Studio subscription benefit. See [additional scenarios](deliver-extended-security-updates.md#additional-scenarios) in the deployment article for more information on how to provision an ESU license correctly for this scenario.
+
+Development, test, and other non-production servers that have a paid operating system license (from your organization's volume licensing key, for example) **must** use a paid ESU license as well. The only servers entitled to ESU licenses at no additional cost are those whose operating system licenses came from a Visual Studio subscription.

 ## Cost savings with migration and modernization of workloads
 
 As you migrate and modernize your Windows Server 2012 and Windows 2012 R2 infrastructure through the end of 2023, you can utilize the flexibility of monthly billing with Windows Server 2012 ESUs enabled by Azure Arc for cost savings benefits.
