First Microsoft Windows [DIRECT · TUTORIAL]

The project that became Windows 1.0 was initially codenamed "Interface Manager." The concept was simple: create a graphical "shell" that sat on top of MS-DOS, allowing users to navigate programs and manage files with a mouse rather than by typing commands.

When users booted it up, they were greeted with a stark, black-and-white screen. Unlike modern Windows, version 1.0 did not allow windows to overlap or "stack" on top of one another. Instead, they "tiled" side-by-side. This design choice was partly to avoid copyright infringement lawsuits from Apple, who claimed ownership over the concept of overlapping windows. first microsoft windows

At the time, personal computers like those running MS-DOS were difficult for the general public to use because they required typing complex commands on a text-only screen. Inspired by early graphical user interfaces (GUIs) developed at Xerox PARC and later seen in Apple’s prototypes, Bill Gates sought to create a graphical "shell" that would sit on top of MS-DOS.

Microsoft officially ended support for Windows 1.0 on December 31, 2001—making it one of the longest-supported products in the company’s history, even though almost no one was using it by the early 1990s. Instead, they "tiled" side-by-side

From a tiled, slow, and often-mocked interface to the most dominant desktop operating system on the planet, the journey of Microsoft Windows had to begin somewhere. And it began on that day in November 1985.

When it finally arrived, Windows 1.0 was a far cry from the polished, powerful operating systems we know today. It wasn't a full operating system; it was an application you launched from within MS-DOS.
