Which windows are open by default when starting a new project in Unity?

When starting a new project in Unity, the default windows that open are the Hierarchy, Inspector, Console, and Scene Window.

The Hierarchy window is essential for managing all the game objects in the current scene, allowing you to see and organize how your game elements relate to one another. The Inspector window provides detailed information about the currently selected game object, enabling you to modify properties and settings easily. The Console window is crucial for viewing logs, warnings, errors, and outputs from scripts, which helps in debugging and tracking the performance of your game. Finally, the Scene Window is where you can visually lay out and manipulate the game environment.

All these windows are integral to the initial workflow in Unity, aiding developers in designing and scripting their projects effectively right from the outset.
