The AWS Command Line Interface (AWS CLI) is a unified tool to manage your AWS services.
To install AWS CLI on Windows, visit the AWS Documentation website to download the installer, select Windows as the operating system, and download the AWS CLI MSI installer.
After the installation is complete, open the Command Prompt or Terminal and configure AWS by entering the access key, secret key, and region.
Once configured, you can test the CLI by running 'aws iam list-users' to see the IAM users created in the Management Console.
