Another link would be the official documentation for the on-demand EC2 pricing stating:

Pricing is per instance-hour consumed for each instance, from the time an instance is launched until it is terminated or stopped. Each partial instance-hour consumed will be billed per-second for Linux, Windows, Windows with SQL Enterprise, Windows with SQL Standard, and Windows with SQL Web Instances, and as a full hour for all other instance types.

Amazon EC2 instances running Windows were historically charged per hour.

However, they are now charged per-second.

As written in your screenshot: "Windows based EC2 instances used to follow pay-per-hour pricing earlier."
