Before Polly this is Ivona and I will show you how to install Polly
Get Started with AWS for Free https://portal.aws.amazon.com/gp/aws/developer/registration/index.html
If you want to use AWS, you generally need to pay using a credit card, Amazon charger $1 for this, and return this amount in five business days
If you need to remove the credit card you only has another valid payment method or credit card
If you decide to close the AWS account because probably recive invoice payments this is the link https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/close-account.html, the credit card info remaining in AWS server .
I suggest in this case Try to Applying for AWS Educate or use a Amazong gift card and you will activate Billing Alerts https://console.aws.amazon.com/billing/home?#/preferences

The below error is thrown when running the command:

The solution
aws configure set region us-east-1 --profile polly-windows
