As the number of services or applications grows, Configuration APIs make it easier to scale allowing to quickly configure multiple instances of services using just a few lines of code.
Configuration APIs of WAS provide deeper access to system settings and allow for custom configurations.
These APIs allow developers to include configuration as part of their Continuous Integration / Continuous Deployment processes.
Application Pool Settings can be automatically adjusted using Configuration APIs depending upon the load to handle the dynamic systems.

Here are the steps to enable it in Windows 11.

Go to the Start menu and open Run Command.
