What basic graphics program is bundled with Windows by Microsoft?

The basic graphics program bundled with Windows by Microsoft is Paint. This application serves as a simple tool for creating and editing images, offering basic functionalities such as drawing shapes, adding text, and filling areas with color. Paint has been included with Windows operating systems for many years, making it widely accessible to users who need basic graphic editing capabilities without the need for advanced software.

In contrast, Photoshop and Illustrator are professional-grade software developed by Adobe that provide extensive features for image editing and graphics creation, but they are not included with Windows by default and typically require a purchase or subscription. GIMP is an open-source alternative to these advanced programs, but it also does not come pre-installed with Windows. Therefore, Paint stands out as the correct answer because it is specifically designed for straightforward graphic tasks and is readily available to all Windows users.
