# AWS Windows AMI reference AWS provides a set of publicly available Amazon Machine Images (AMIs) that contain software configurations specific to the Windows platform. You can quickly start building and deploying your applications with Amazon EC2 by using these AMIs. First choose the AMI that meets your specific requirements, and then launch an instance using that AMI. You retrieve the password for the administrator account and then log in to the instance using Remote Desktop Connection, just as you would with any other Windows Server. In general, the AWS Windows AMIs are configured with the default settings used by the Microsoft installation media. However, Amazon does apply some customizations. For example, the AWS Windows AMIs come with the following software and drivers: + EC2Launch v2 (Windows Server 2022 and 2025) + EC2Launch v1 (Windows Server 2016 and 2019) + EC2Config (through Windows Server 2012 R2) + AWS Systems Manager + AWS CloudFormation + AWS Tools for Windows PowerShell + Network drivers (SRIOV, ENA, Citrix PV) + Storage drivers (NVMe, AWS PV, Citrix PV) + Graphics drivers (NVidia GPU, Elastic GPU) With the Windows fast launch feature, you can configure pre-provisioned snapshots to launch instances up to 65% faster. For more information, see [Configure Windows fast launch for your Windows Server AMI](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/win-ami-config-fast-launch.html) in the *Amazon EC2 User Guide*. To view changes to each release of the AWS Windows AMIs, including SQL Server updates, see the [AWS Windows AMI version history](ec2-windows-ami-version-history.md). # Specialized AWS Windows AMIs In addition to its standard operating system version AMIs, Amazon creates the following types of specialized AWS Windows AMIs: **SQL Server license-included AMIs** Launching an instance from a Windows AMI with Microsoft SQL Server enables you to run the instance as a database server. For more information, see [AWS Windows Server license-included SQL Server AMIs](ami-windows-sql.md). **STIG Hardened AMIs** STIG Hardened EC2 Windows Server AMIs are pre-configured with over 160 required security settings to help ensure that the instances that you launch follow the latest guidelines for STIG compliance. For more information, see [STIG Hardened AWS Windows Server AMIs](ami-windows-stig.md). **NitroTPM enabled AMIs** Amazon creates a set of AMIs that are pre-configured with NitroTPM and UEFI Secure Boot requirements. For more information, see [AWS Windows Server NitroTPM enabled AMIs](ami-windows-tpm.md). You can also create your own customized AMI from one of the AWS Windows AMIs with EC2 Image Builder. For more information, see the [EC2 Image Builder User Guide](https://docs.aws.amazon.com/imagebuilder/latest/userguide/). We recommend PowerShell for the command line examples in this section. To install PowerShell in your environment, see the [Installation](https://docs.aws.amazon.com/powershell/v4/userguide/pstools-getting-set-up.html) page in the *AWS Tools for PowerShell (version 4) User Guide*. **Note** Not all AMIs are available in all Regions. ## Find an AWS Windows AMI Each of the specialized AMI pages linked above has its own filtered search examples, as follows: + [Find Windows Server AMIs with Microsoft SQL Server](ami-windows-sql.md#ami-windows-sql-find) + [Find a STIG Hardened AMI](ami-windows-stig.md#find-windows-stig-ami) + [Find Windows Server AMIs configured with NitroTPM and UEFI Secure Boot](ami-windows-tpm.md#ami-windows-tpm-find) You can also search for the latest Windows AMIs that include the EC2Launch v2 agent, as shown in the following PowerShell example: ``` Get-SSMLatestEC2Image ` -Path ami-windows-latest ` -ImageName EC2LaunchV2-Windows* | ` Sort-Object Name ``` **Note** If this command doesn't run in your environment, you might be missing a PowerShell module. For more information about this command, see [Get-SSMLatestEC2Image Cmdlet](https://docs.aws.amazon.com/powershell/v4/reference/items/Get-SSMLatestEC2Image.html). Alternatively, you can use the [CloudShell console](https://console.aws.amazon.com/cloudshell/home) and run `pwsh` to bring up a PowerShell prompt that already has all of the AWS tools installed. For more information, see the [AWS CloudShell User Guide](https://docs.aws.amazon.com/cloudshell/latest/userguide/welcome.html). ### Find an AWS Windows AMI in a specific language The following language-specific AWS Windows AMIs are included in the monthly release: + English + Japanese + Chinese + Korean + Czech + Dutch + French + German + Hungarian + Italian + Polish + Russian + Portuguese + Spanish + Swedish + Turkish The following example uses PowerShell to search for the latest English language AWS Windows AMIs: ``` Get-SSMLatestEC2Image ` -Path ami-windows-latest ` -ImageName *Windows_Server-*English* | ` Sort-Object Name ``` **Note** If this command doesn't run in your environment, you might be missing a PowerShell module.

For more information, see the [AWS CloudShell User Guide](https://docs.aws.amazon.com/cloudshell/latest/userguide/welcome.html). # AWS Windows Server license-included SQL Server AMIs AWS Windows AMIs with Microsoft SQL Server include one of the following SQL Server editions. Launching an instance from a Windows AMI with Microsoft SQL Server enables you to run the instance as a database server. + SQL Enterprise Edition + SQL Server Standard + SQL Server Express + SQL Server Web For more information about running Microsoft SQL Server on EC2, see the [Microsoft SQL Server on Amazon EC2 User Guide](https://docs.aws.amazon.com/sql-server-ec2/latest/userguide/sql-server-on-ec2-overview.html). Each AWS Windows AMIs with Microsoft SQL Server AMI also includes the following features: + Automatic Windows and SQL Server updates + SQL Server Management Studio included + Preconfigured SQL Server service accounts ## Find Windows Server AMIs with Microsoft SQL Server AWS managed AMIs always include the AMI creation date as part of the name. The best way to ensure that your search returns the AMIs that you're looking for is to add date filtering for the name. Use one of the following command line options to find an AMI. ------ #### [ AWS CLI ] **Find the latest SQL AMIs** The following example retrieves a list of the latest Windows Server AMIs that include Microsoft SQL Server. ``` aws ssm get-parameters-by-path \ --path "/aws/service/ami-windows-latest" \ --recursive \ --query 'Parameters[*].{Name:Name,Value:Value}' \ --output text | grep ".*Windows_Server-.*SQL.*" | sort ``` **Find a specific AMI** The following example retrieves Windows Server AMIs with Microsoft SQL Server by filtering on the AMI name, the owner, the platform, and the creation date (year and month). Output is formatted as a table with columns for the AMI name and image ID. ``` aws ec2 describe-images \ --owners amazon \ --filters \ "Name=name,Values=*SQL*" \ "Name=platform,Values=windows" \ "Name=creation-date,Values=2025-05*" \ --query 'Images[].[Name,ImageId]' \ --output text | sort ``` ------ #### [ PowerShell (recommended) ] **Find the latest SQL AMIs** The following example retrieves a list of the latest Windows Server AMIs that include Microsoft SQL Server. ``` Get-SSMLatestEC2Image ` -Path ami-windows-latest ` -ImageName *Windows_Server-*SQL* | Sort-Object Name ``` **Note** If this command doesn't run in your environment, you might be missing a PowerShell module. For more information about this command, see [Get-SSMLatestEC2Image Cmdlet](https://docs.aws.amazon.com/powershell/v4/reference/items/Get-SSMLatestEC2Image.html). Alternatively, you can use the [CloudShell console](https://console.aws.amazon.com/cloudshell/home) and run `pwsh` to bring up a PowerShell prompt that already has all of the AWS tools installed. For more information, see the [AWS CloudShell User Guide](https://docs.aws.amazon.com/cloudshell/latest/userguide/welcome.html). **Find a specific AMI** The following example retrieves Windows Server AMIs with Microsoft SQL Server by filtering on the AMI name, the owner, the platform, and the creation date (year and month). Output is formatted as a table with columns for the AMI name and image ID. ``` Get-EC2Image ` -Owner amazon ` -Filter @( @{Name = "name"; Values = @("*SQL*")} @{Name = "platform"; Values = @("windows")} @{Name = "creation-date"; Values = @("2025-*")} ) | Sort-Object Name | Format-Table Name, ImageID -AutoSize ``` ------ # STIG Hardened AWS Windows Server AMIs Security Technical Implementation Guides (STIGs) are the configuration standards created by the Defense Information Systems Agency (DISA) to secure information systems and software. DISA documents three levels of compliance risk, known as categories: + **Category I** — The highest level of risk. It covers the most severe risks, and includes any vulnerability that can result in a loss of confidentiality, availability, or integrity. + **Category II** — Medium risk. + **Category III** — Low risk. Each compliance level includes all STIG settings from lower levels. This means that the highest level includes all applicable settings from all levels. To ensure that your systems are compliant with STIG standards, you must install, configure, and test a variety of security settings. STIG Hardened EC2 Windows Server AMIs are pre-configured with over 160 required security settings. Amazon EC2 supports the following operating systems for STIG Hardened AMIs: + Windows Server 2022 + Windows Server 2019 + Windows Server 2016 + Windows Server 2012 R2 The STIG Hardened AMIs include updated Department of Defense (DoD) certificates to help you get started and achieve STIG compliance. STIG Hardened AMIs are available in all commercial AWS and GovCloud (US) Regions. You can launch instances from these AMIs directly from the Amazon EC2 console. They are billed using standard Windowspricing. There are no additional charges for using STIG Hardened AMIs. The following sections list the STIG settings that Amazon applies to WindowsOperating Systems and components. **Topics** + [Find a STIG Hardened AMI](#find-windows-stig-ami) + [Core and base operating systems](#base-os-stig) + [Microsoft .NET Framework 4.0 STIG Version 2 Release 6](#dotnet-os-stig) + [WindowsFirewall STIG Version 2 Release 2](#windows-firewall-stig) + [Internet Explorer (IE) 11 STIG Version 2 Release 5](#ie-os-stig) + [Microsoft Edge STIG Version 2 Release 2](#edge-stig) + [Microsoft Defender STIG Version 2 Release 4](#defender-stig) + [Version history](#stig-version-history) ## Find a STIG Hardened AMI You can search for a STIG Hardened EC2 Windows Server AMI when you launch an instance from the EC2 console, or you can search for an AMI in the CLI or in PowerShell, as follows. **Name patterns for STIG Hardened Windows AMIs** + Windows\$1Server-2022-English-STIG-Full-*YYYY.MM.DD* + Windows\$1Server-2022-English-STIG-Core-*YYYY.MM.DD* + Windows\$1Server-2019-English-STIG-Full-*YYYY.MM.DD* + Windows\$1Server-2019-English-STIG-Core-*YYYY.MM.DD* + Windows\$1Server-2016-English-STIG-Full-*YYYY.MM.DD* + Windows\$1Server-2016-English-STIG-Core-*YYYY.MM.DD* + Windows\$1Server-2012-R2-English-STIG-Full-*YYYY.MM.DD* + Windows\$1Server-2012-R2-English-STIG-Core-*YYYY.MM.DD* ------ #### [ Console ] You can select an AMI from the **Community AMIs** tab when you launch an instance, as follows. **Launch an EC2 instance with a STIG Hardened Windows Server AMI** 1.

The best way to ensure that your search returns the AMIs that you're looking for is to add date filtering for the name. Use one of the following command line options to find an AMI. ------ #### [ AWS CLI ] **Find the latest NitroTPM and UEFI Secure Boot AMIs** The following example retrieves a list of the latest Windows Server AMIs that are configured for NitroTPM and UEFI Secure Boot. ``` aws ssm get-parameters-by-path \ --path "/aws/service/ami-windows-latest" \ --recursive \ --query 'Parameters[*].{Name:Name,Value:Value}' \ --output text | grep "TPM-Windows_Server" | sort ``` **Find a specific AMI** The following example retrieves Windows Server AMIs that are configured for NitroTPM and UEFI Secure Boot by filtering on the AMI name, the owner, the platform, and the creation date (year and month). Output is formatted as a table with columns for the AMI name and image ID. ``` aws ec2 describe-images \ --owners amazon \ --filters \ "Name=name,Values=TPM-Windows_Server-*" \ "Name=platform,Values=windows" \ "Name=creation-date,Values=2025-05*" \ --query 'Images[].[Name,ImageId]' \ --output text | sort ``` ------ #### [ PowerShell (recommended) ] **Find the latest NitroTPM and UEFI Secure Boot AMIs** The following example retrieves a list of the latest Windows Server AMIs that are configured for NitroTPM and UEFI Secure Boot. ``` Get-SSMLatestEC2Image ` -Path ami-windows-latest ` -ImageName TPM-Windows* | Sort-Object Name ``` **Note** If this command doesn't run in your environment, you might be missing a PowerShell module. For more information about this command, see [Get-SSMLatestEC2Image Cmdlet](https://docs.aws.amazon.com/powershell/v4/reference/items/Get-SSMLatestEC2Image.html). Alternatively, you can use the [CloudShell console](https://console.aws.amazon.com/cloudshell/home) and run `pwsh` to bring up a PowerShell prompt that already has all of the AWS tools installed. For more information, see the [AWS CloudShell User Guide](https://docs.aws.amazon.com/cloudshell/latest/userguide/welcome.html). **Find a specific AMI** The following example retrieves Windows Server AMIs that are configured for NitroTPM and UEFI Secure Boot by filtering on the AMI name, the owner, the platform, and the creation date (year and month). Output is formatted as a table with columns for the AMI name and image ID. ``` Get-EC2Image ` -Owner amazon ` -Filter @( @{Name = "name"; Values = @("TPM-Windows*")} @{Name = "platform"; Values = @("windows")} @{Name = "creation-date"; Values = @("2026*")} ) | Sort-Object Name | Format-Table Name, ImageID -AutoSize ``` ------ # How Amazon creates AWS Windows AMIs The following content is a high level overview of the process Amazon uses to create AWS Windows AMIs. Details include what you can expect from an official AWS Windows AMI, as well as the standards that Amazon uses to validate AMI security and reliability. ## Where AWS gets the Windows Server installation media When a new version of Windows Server is released, we download the Windows ISO from Microsoft and validate the hash Microsoft publishes. An initial AMI is then created from the Windows distribution ISO. The drivers needed to boot on EC2 are included in addition to our EC2 launch agent. To prepare this initial AMI for public release, we perform automated processes to convert the ISO to an AMI. This prepared AMI is used for the monthly automated update and release process. ## What to expect from an official AWS Windows AMI Amazon provides AWS Windows AMIs with a variety of configurations for popular versions of Microsoft supported Windows Server Operating Systems. As outlined in the previous section, we start with the Windows Server ISO from Microsoft’s Volume Licensing Service Center (VLSC) and validate the hash to ensure it matches Microsoft’s documentation for new Windows Server operating systems. We perform the following changes using automation on AWS to take the current Windows Server AMIs and update them: + Install all Microsoft recommended Windows security patches. We release images shortly after the monthly Microsoft patches are made available. + Install the latest drivers for AWS hardware, including network and disk drivers, the EC2WinUtil utility for troubleshooting, as well as GPU drivers in selected AMIs. + Include the following AWS launch agent software by default: + [https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2launch-v2.html](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2launch-v2.html) for Windows Server 2022 and 2025, and optionally for Windows Server 2019 and 2016 with specific AMIs. + [https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2launch.html](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2launch.html) for Windows Server 2016 and 2019. + [https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2config-service.html](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2config-service.html) for Windows Server 2012 R2 and earlier. + Configure Windows Time to use the [Amazon Time Sync Service](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/set-time.html). + Change all power schemes to set the display to never turn off. + Perform minor bug fixes – generally one-line registry changes to enable or disable features that we have found to improve performance on AWS. + Tests and validates AMIs across new and existing EC2 platforms to help ensure compatibility, stability, and consistency before release. For a more detailed list that includes initialization, installation, and configuration settings that are applied, see [Updates applied for AWS Windows AMIs](windows-ami-configuration.md). ## How Amazon validates security, integrity, and authenticity of software on AMIs We take a number of steps during the image build process, to maintain the security, integrity, and authenticity of AWS Windows AMIs. A few examples include: + AWS Windows AMIs are built using source media obtained directly from Microsoft. + Windows Updates are downloaded directly from Microsoft’s Windows Update Service by Windows, and installed on the instance used to create the AMI during the image build process. + AWS Software is downloaded from secure S3 buckets and installed in the AMIs. + Drivers, such as for the chipset and GPU, are obtained directly from the vendor, stored in secure S3 buckets, and installed on the AMIs during the image build process. ## How Amazon decides which AWS Windows AMIs to offer Each AMI is extensively tested prior to release to the public. We periodically streamline our AMI offerings to simplify customer choice and to reduce costs. + New AMI offerings are created for new OS releases. You can count on Amazon releasing *Base*, *Core*, and *SQL Express/Standard/Web/Enterprise* offerings in English and other widely used languages. The primary difference between Base and Core offerings is that Base offerings have a desktop/GUI whereas Core offerings are PowerShell command line only. For more information, see [Windows Server Core](https://learn.microsoft.com/en-us/windows-server/administration/server-core/what-is-server-core) on the Microsoft website. + New AMI offerings are created to support new platforms – for example, the Deep Learning andNvidia AMIs were created to support customers using our GPU-based instance types (P2 and P3, G3, and others). + Less popular AMIs are sometimes removed. If we see a particular AMI is launched only a few times in its entire lifespan, we will remove it in favor of more widely used options. If there is an AMI variant that you would like to see, let us know by opening a support case, or by [providing feedback](https://repost.aws/knowledge-center/send-feedback-aws). ## Patches, security updates, and AMI IDs Amazon provides updated, fully-patched AWS Windows AMIs within five business days of Microsoft's patch Tuesday (the second Tuesday of each month). The new AMIs are available immediately from the **Images** page in the Amazon EC2 console. The new AMIs are available in the AWS Marketplace and the **Quick Start** tab of the launch instance wizard within a few days of their release. **Note** Instances launched from Windows Server 2019 and later AMIs may show a Windows Update dialog message stating "Some settings are managed by your organization." This message appears as a result of changes in Windows Server 2019 and does not impact the behavior of Windows Update or your ability to manage update settings. To remove this warning, see ["Some settings are managed by your organization"](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/common-messages.html#some-settings-managed-by-org). AWS Windows AMIs are publicly available for three months after they are released. Within 10 days after the release of new AMIs, AWS changes access for AMIs that are more than three months old to make them private. After AWS makes an AMI private, you may no longer retrieve it by any method. In the console, the **AMI ID** field for a private AMI states, `Cannot load detail for ami-1234567890abcdef0. You may not be permitted to view it.` If an AMI is deprecated but is not yet marked private, you can still use it. However, we recommend that you always use the latest version. The AWS Windows AMIs; in each release have new AMI IDs. Therefore, we recommend that you write scripts that locate the latest AWS Windows AMIs by their names, rather than by their IDs.

These AMIs include the following high-level changes between AWS Windows AMIs for different Windows operating system versions: ## Windows Server 2025 + Windows Server 2025 AMIs use UEFI boot mode by default, except for Windows Server 2025 AMIs named `BIOS-Windows_Server-2025-English-Full-Base`. **Note** EC2 metal instance sizes and some EC2 instance types do not support UEFI boot mode for Windows Server. To launch Windows Server 2025 on these instances, you must use the AWS managed `BIOS-Windows_Server-2025-English-Full-Base` AMI, or an AMI that is based on that image. For more information about UEFI requirements, [Requirements for UEFI boot mode](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/launch-instance-boot-mode.html) in the *Amazon EC2 User Guide*. + Windows Server 2025 AMIs support Nitro EC2 instance types only. + Windows Server 2025 AMIs use `gp3` EBS volume types by default. + Windows Server 2025 AMIs use the AWS.Tools PowerShell module. ## Windows Server 2016-2022 + To accommodate the change from .NET Framework to .NET Core, the EC2Config service has been deprecated on Windows Server 2016 AMIs and replaced by EC2Launch. EC2Launch is a bundle of Windows PowerShell scripts that perform many of the tasks performed by the EC2Config service. For more information, see [Configure a Windows instance using EC2Launch](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2launch.html). EC2Launch v2 replaces EC2Launch in Windows Server 2022 and later. For more information, see [Configure a Windows instance using EC2Launch v2](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2launch-v2.html). + On earlier versions of Windows Server AMIs, you can use the EC2Config service to join an EC2 instance to a domain and configure integration with Amazon CloudWatch. On Windows Server 2016 and later AMIs, you can use the CloudWatch agent to configure integration with Amazon CloudWatch. For more information about configuring instances to send log data to CloudWatch, see [Collect Metrics and Logs from Amazon EC2 Instances and On-Premises Servers with the CloudWatch Agent](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Install-CloudWatch-Agent.html). For information about joining an EC2 instance to a domain, see [ Join an Instance to a Domain Using the `AWS-JoinDirectoryServiceDomain` JSON Document](https://docs.aws.amazon.com/systems-manager/latest/userguide/walkthrough-powershell.html#walkthrough-powershell-domain-join) in the *AWS Systems Manager User Guide*. **Other differences** Note the following additional important differences for instances created from Windows Server 2016 and later AMIs. + By default, EC2Launch does not initialize secondary EBS volumes. You can configure EC2Launch to initialize disks automatically by either scheduling the script to run or by calling EC2Launch in user data.

These images include EC2Launch v2 and serve as a functional preview of the new launch agent in advance of it being included by default on all AWS Windows AMIs currently provided by AWS later this year. Note that some SSM documents and dependent services, such as EC2 Image Builder, may require updates to support EC2 Launch v2. These updates will follow in the coming weeks. These images are not recommended for use in production environments.

In the near future, all Windows Server AMIs currently provided by AWS will be migrated to use EC2Launch v2 by default as part of the monthly release. EC2Launch v1V2\$1Preview AMIs will be updated monthly and remain available until this migration occurs.
