35 years of Microsoft operating systems: Windows history: from 1.0 to 10

On November 20, 1985, the then small software company Microsoft released the first graphical user interface for its operating system MS-DOS with Windows 1.0. Initially only programmed as an extension of the operating system, Windows 1.0 lays the foundation for an unprecedented success story. Applications on MS-DOS computers can now be operated with the mouse, making the gray boxes attractive for the consumer market.

However, a race against time flared up 30 years ago for the first graphical user interface for the use of PCs. Personal computers are usually used in companies at this time. Bill Gates quickly realizes that a graphical user interface (GUI) would be necessary so that one day the computer would find its place on every desk.

Under Microsoft’s first operating system, MS-DOS, users must already have a certain level of technical know-how in order to operate the computer. Basic knowledge of the Basic programming language was an advantage at the time. However, the first version of Windows still has very little resemblance to the graphical user interfaces as we know them today. The software is bulky, slow and is only supported by a few applications. If you want to start a small program like the calculator, you have to search for the required file (calc.exe) in the depths of the operating system and then start it from the command line.
