On November 20, 1985, the IT giant Microsoft released Windows 1.0, the first operating system in the Windows series, which today has reached Windows 11. This operating system promised to change the relationship with personal computers forever thanks to a simple to use graphical environment, capable of working alongside the command lines of MS-DOS. Marketed at a price of $99, it included basic applications such as Paintbrush, Notepad, Calculator, a version of the Reversi game and a Control Panel for customizing the system. Bill Gates, co-founder of Microsoft, spoke of a platform designed for those who considered the PC a serious productivity tool, capable of offering a «unprecedented power» and pave the way for future hardware and software innovations. The goal was to bring one to life GUIacronym for Graphical User Interfacethat is, a graphical user interface that allows you to interact with the computer through visual elements and the mouse, instead of just typing text commands.
At the time, however, not everyone was convinced by the novelty: many professionals considered graphics systems to be a whim, expensive in terms of memory and performance. Windows 1.0 was greeted with skepticism, criticized for its slowness and lack of compatible software. Yet it brought with it dynamics that we still find today in practically all major operating systems, desktop and mobile: basic multitasking, a stable API for developers and the desire to create a shared ecosystem between different hardware manufacturers. In this in-depth analysis we will take a closer look at how the project was born, what challenges it encountered and what functions made it the ancestor of everything we consider “normal” when we use a modern Windows PC.
How and when Windows 1.0 was born
Windows 1.0 didn’t come out of nowhere. Microsoft had been working on the idea of a system oriented towards the use of mice and graphics since 1981, but the real push came when Gates saw a demonstration of Visi On, a competing graphics suite, during the 1982 COMDEX technology fair. From that moment on, creating his own visual environment became a priority for Gates’ company. Scott A. McGregor, a key figure in the development of window systems at the famous Xerox PARC center, was brought in to lead the project.
The development of Windows 1.0 continued until November 1983, when it was revealed to the public for the first time, but its release was so late that the media of the time began to talk about vaporwarea neologism coined precisely in that period and which still today sarcastically refers to products announced with great enthusiasm but which seem to “evaporate” without ever actually arriving on the market. In November 1985 Microsoft was finally ready to release its creature. In remembering that moment, the specialized site The Verge tells:
On November 20, 1985, the company shipped the operating system, and the next evening Microsoft threw its own party at the Comdex trade show in Las Vegas. InfoWorld editor Stewart Alsop presented Bill Gates with the Golden Vaporware award, mocking the missed release dates. (…) Microsoft threw dry ice into buckets of water in a failed attempt (given the dry air of Las Vegas) to produce real steam.
The features of Windows 1.0
Windows 1.0 functioned as a sort of “graphics layer” on top of MS-DOS. Most modern applications designed for Windows could run in non-overlapping windows, while traditional DOS software took up the entire screen. The choice of non-overlapping windows might seem rigid, but it had the aim of containing memory consumption: the minimum configuration involved the use of just two floppy disk drives and 192 KB of RAM.
The mouse was already present and the system encouraged mouse operations click-and-dragdragging and dropping items, although you had to hold down the button to open the menus, which is different from current standards. Among the most useful applications were Paintbrush (the ancestor of Paint), Write (a rudimentary word processor), a communications terminal and Cardfile, a sort of digital filing cabinet. The interface introduced a bar at the bottom where the reduced application icons ended up, a solution reminiscent of the taskbar introduced later, with the advent of Windows 95.
From a technical point of view, Windows integrated three fundamental libraries: KERNELdedicated to memory and activity management; USERresponsible for the interface and dialogue with the user; GDIthe graphics part responsible for drawing elements on the screen. These components would define the foundation of Windows architecture for many years.
The concept of “window”, which gave its title to the operating system itself, was also taken up in a stylized form in the Windows 1.0 logo, which showed a rectangle with rounded corners divided into four sectors. This graphic idea became iconic and remained at the center of the evolution of the Windows logo for four decades.
The reception of Windows 1.0 on the market
Despite the ambitions and expectations placed by Microsoft, the reception of Windows 1.0 on the market was not the best. Critics and industry journalists complained about poor performance on machines with 512 KB of RAM, limited compatibility with existing software and a non-trivial learning curve for those who had never used a mouse. Just to give you an example, in an article on New York Times claimed that “running Windows on a PC with 512K of memory is like pouring molasses in the Arctic». Despite the lukewarm reception from critics and tech enthusiasts, to say the least, the project continued to evolve, with updates up to version 1.04 and technical support that lasted until December 31, 2001, longer than any other edition of Windows. And today, 40 years after then, the Windows operating system is one of the most widespread in the world.
