This has since produced several different versions of Linux, including one called Lindows. Lindows is exactly what you would expect from the name. It is a version of Linux that looks and acts exactly like a modern version of Windows. At first, both operating systems seemed promising for a brighter future for computing. However, one of them grew exponentially while the other was ignored. Windows became the world's leading operating system in no time. It was created by Microsoft with the logo being a colored window with the colors red, green, blue and yellow. It offered a user-friendly point-and-click interface that was completely different from that of the time, and then continued to innovate it.
