40 years of Windows: From DOS shell to an agentic OS enigma

A Monumental Leap: Windows 1.0 Turns 40

Forty years ago, on November 20, 1985, a nascent Microsoft unleashed Windows 1.0 upon the world. This wasn't the all-encompassing operating system we know today; rather, it was a sophisticated graphical shell built atop MS-DOS. Designed for PCs powered by Intel 8088 processors with a modest 256KB of RAM, it introduced a revolutionary paradigm: tiled windows, menus, and crucially, mouse input, all layered over the familiar DOS environment. It was less an OS and more a visionary skin, one that profoundly shaped the trajectory of graphical user interfaces for decades to come.

Evolution of the Window: From Tiled to Overlapping and Beyond

The early years of Windows were a period of rapid, almost breathless, innovation. December 1987 saw the arrival of Windows 2.0, which finally granted windows the ability to overlap and be resized, a fundamental step towards the flexible desktop we now take for granted. The 1990s ushered in Windows 3.0 and its successor, 3.1, in 1990 and 1992 respectively. These iterations brought a significant facelift, introducing the Program Manager, intuitive icons, the game-changing TrueType fonts, and rudimentary multimedia capabilities. This was the era when Windows truly began its ascent to ubiquity on personal computers.

The Dawn of Modern Windows: From '95 to the XP Era

The seismic shift occurred with Windows 95 in August 1995. It unveiled the iconic Start menu, the omnipresent taskbar, and a predominantly 32-bit desktop, fundamentally altering user interaction. Subsequent releases like Windows 98, Me, and 2000 refined this experience, incorporating enhanced USB support, power management features, and the robust NT kernel. The year 2001 marked a pivotal moment with Windows XP, which masterfully consolidated both consumer and business editions into a single, remarkably stable platform. Vista, launched in 2007, attempted to dazzle with its transparent Aero interface and a new driver model, though its reception was mixed.

The Zenith and the Shift: Windows 7 and the Modern Conundrum

Windows 7, released in 2009, is often hailed by many as the apogee of Windows development, a harmonious blend of power and usability. Fast forward to today, and Windows 11, a successor to Windows 10, inherits much of its core. Despite being technically an extension of Windows 10, significant UI overhauls, such as the new Settings app, a sometimes cluttered interface, numerous integrated services, and a propensity for update-related glitches, have met with user apprehension. This lukewarm reception has been further exacerbated by Microsoft's announced ambition to transform Windows into an 'agentic OS' – a move that feels like a departure from listening to what users truly desire.

Personal Reflections and the Enduring Appeal of Control

For this writer, the journey began with Windows 98, preceded by DOS and Windows 95, which was the first truly mainstream Windows in my region. The earlier Windows 1-3 iterations remained niche, and PCs were a rarer commodity in the final two decades of the 20th century. The undeniable strengths of Windows have always been its user-friendly graphical interface, simplifying tasks that seem laughably basic now, and its vast software ecosystem, which cemented its status as the dominant desktop operating system. I've always found a deep satisfaction in customizing my computing environment, installing the programs I need, rather than having a Microsoft functionary or an AI dictate my digital destiny. The idea of relinquishing that control is, frankly, unsettling.
