# Installing the Amazon Tools for PowerShell on Windows
<a name="pstools-getting-set-up-windows"></a>

For information about the Tools for PowerShell that are pre-installed on Amazon CloudShell, see [Installed on CloudShell](pstools-getting-set-up-cloudshell.md).

A Windows-based computer can run any of the Amazon Tools for PowerShell package options:
+ [**`AWS.Tools`**](ps-installing-awstools.md) - The modularized version of Amazon Tools for PowerShell. Each Amazon service is supported by its own individual, small module, with shared support modules `AWS.Tools.Common` and `AWS.Tools.Installer`.
+ [**AWSPowerShell.NetCore**](ps-installing-awspowershellnetcore.md) - The single, large-module version of Amazon Tools for PowerShell. All Amazon services are supported by this single, large module.
**Note**  
Be aware that the single module might be too large to use with [Amazon Lambda](http://www.amazonaws.cn/lambda/) functions. Instead, use the modularized version shown above.
+ [**AWSPowerShell**](ps-installing-awswindowspowershell.md) - The legacy, Windows-specific, single, large-module version of Amazon Tools for PowerShell. All Amazon services are supported by this single, large module.

The package you choose depends on the release and edition of Windows that you are running.

**Note**  
The Amazon Tools for PowerShell are installed by default on all Windows-based Amazon Machine Images (AMIs). The option that is installed depends on the AMI. Many AMIs have the AWSPowerShell module, but some might have a different option. For example, Amazon EC2 AMIs for Windows Server 2025 use the modular `AWS.Tools` option.

Setting up the Amazon Tools for PowerShell involves the following high-level tasks, described in detail in subsequent topics.

1. Install the Amazon Tools for PowerShell package option that's appropriate for your environment.
