Over the last decades, Microsoft has successfully established a monopoly in the desktop operating system market. Key to the company’s success were deals with PC manufacturers to have its software preinstalled on computers. Microsoft keeps its contracts with top « Original Equipment Manufacturers » like HP and Gateway secret. These corporations get very cheap Windows licenses in return for certain favors. Among other things, OEMs may not install a competing operating system on PCs that also run Windows. (This is explained in detail in my previous article Microsoft’s Dirty OEM Secret.) Now, according to an article in the New York Times , a Microsoft executive has openly defended this practice, with specific reference to Linux, before the United States District Court for the District of Columbia.
