Windows applicationsĮach of the operating systems most used today around the world, such as Windows, Mac OS and Linux, have a series of applications or programs installed by default that will help you to fulfill different types of tasks until you do the installation of your favorite programs . That is why, no matter how basic or old a program is, if it is installed by default in your computer’s operating system, it is worth reviewing it. Over the years, the development of new programs and the constant updating of others, have made basic programs on your computer little more than forgotten. A good example of this is Paint, the classic program with its function of drawing a grid .
