First of all let me tell you one thing that before microsoft there was very little scope for personal computers and softwares related to those computers. Still there were some softwares and software building programming languages. FORTRAN or formula translation, the first high level programming language, was invented by John Backus for IBM, in 1954, and released commercially, in 1957. It is still used today for programming scientific and mathematical applications. Fortran began as a digital code interpreter for the IBM 701 and was originally named Speedcoding. John Backus wanted a programming language closer to human language, which is the definition of a high level language.

At that time the softwares available were Aldus Pagemaker, Trillian, Wordstar, Computer Chess, VisiCalc Spreadsheet. WordStar - The First Word Processor Released in 1979 by Micropro International, WordStar was the first commercially successful word processing software program produced for microcomputers and the best selling software program of the early eighties. first desktop publishing program was created by Paul Brainard and a company called Aldus, the program called "Aldus Pagemaker 1.0" was released in July, 1985 for the "Macintosh" and in December, 1986, for the "IBM". If you go with the history of operating system than previously there was nothing except UNIX.What computer software were computers using before Microsoft was invented?DOS (disk operating system)What computer software were computers using before Microsoft was invented?Before Apple there was Windows 3.1.
