The first version of Microsoft’s PC operating system hit the market 35 years ago. It was so bad it could have been the latest version. But even then, Microsoft proved its greatest virtue: perseverance.
In November 1985 the moment had finally arrived: after a long and tiring development time, the ambitious product was ready for publication: the graphical user interface of Microsoft, with which Bill Gates and his colleagues wanted to keep up with their great competitor Apple.
Two years earlier, in January 1983, Apple had provided an impressive model with the Lisa desktop computer of how computers would be used in the future: with a mouse and a self-explanatory user interface. Microsoft’s main product at the time was the DOS operating system, which was controlled via the so-called prompt, the command input line that could only be used meaningfully if you knew the most important commands by heart.
