This week marks a major milestone: Microsoft’s Windows turns 40. The operating system that began life in 1985 as a clunky graphical add-on for command-line computers has evolved into the most recognizable name in personal computing. From bulky beige desktops to sleek, cloud-connected laptops, Windows has been a companion for every generation of users — through triumphs, flops, and the occasional blue screen of death.
It all started on November 20, 1985, when Microsoft launched the first version of Windows. Although humble in appearance — windows couldn’t even overlap — it introduced a revolutionary idea: making computers visual and clickable. With a mouse and icons, users could finally interact with their PCs without memorizing cryptic DOS commands.
At that time, Apple’s Macintosh had already popularized the friendly graphical interface, while IBM’s machines ruled the professional world. Microsoft aimed to merge familiarity with accessibility. It took several iterations, but the vision eventually defined how billions use computers today.
Across four decades, Windows has seen dramatic highs and frustrating lows. Here’s a quick tour through the milestones:
A reader poll revealed that Windows XP remains the fan favorite, drawing 35% of votes, followed by Windows 7 at 17%. Clearly, stability and familiarity are tough to beat.
Today, Windows powers over a billion devices worldwide — from gaming rigs to portable workstations and ARM-based tablets. But it’s no longer just about the desktop. The platform now connects seamlessly to Office, Xbox, Edge, and the vast Azure cloud infrastructure. With the rise of AI tools such as Copilot, Windows is evolving into an intelligent assistant woven into everyday tasks.
Even with fierce competition from Linux devotees, Chromebooks, and mobile-first ecosystems, Windows remains the foundation of modern computing. For millions, it’s not just software — it’s part of everyday life, the digital backdrop to work, creativity, and nostalgia.
What lies beyond 40? Rumors suggest Windows 12 is on the way, featuring deeper cloud integration, enhanced AI support, and perhaps a modular design adaptable to various devices. However it appears, one truth endures: Microsoft’s Windows remains the defining interface of personal computing.
