Its just a basic graphic editing tool thrown in with Windows, so that people could mess around with pictures. Whilst it obviously doesn't compete with professional graphics software, it provides a distraction, and a way of saving bmps and jpgs of screen dumps with no additional software.
Paint (formerly Paintbrush for Windows) is a simple graphics painting program that has been included with almost all versions of Microsoft Windows since its first release. It is often referred to as MS Paint or Microsoft Paint. The program opens and saves files as Windows bitmap (24-bit, 256 color, 16 color, and monochrome, all with the .bmp extension), JPEG, GIF (without animation or transparency, although the Windows 98 version and a Windows 95 upgrade did support the latter), PNG (without alpha channel), and TIFF. The program can be in color mode or two-color black-and-white, but there is no grayscale mode.
