Microsoft, in conjunction with the Computer History Museum in Silicon Valley, has released the source code for MS-DOS 1.1, MS-DOS 2.0, and Word for Windows 1.1a. These programs are probably the three most important releases in the history of Microsoft: MS-DOS would create and secure Microsoft’s monopoly of the PC market for more than 20 years, and the massive success of Word for Windows would go on to cultivate Microsoft’s Office suite, which has generated hundreds of billions of dollars for the company.
