Introduction

Few software products have transformed the world as profoundly as Microsoft Windows. Since its first release in 1985, Windows has become the world’s most widely used desktop operating system, powering billions of computers in homes, schools, businesses, and governments. For nearly four decades, it has played a central role in shaping how people work, learn, communicate, and create.

From simple graphical interfaces to today’s AI-powered computing experiences, Windows has continually evolved alongside advances in computer technology. Whether used for office work, gaming, software development, education, scientific research, or creative design, Windows remains one of the most influential software platforms in history.

The Birth of Microsoft

Microsoft was founded on April 4, 1975, by Bill Gates and Paul Allen in Albuquerque, New Mexico. Their original goal was to develop software for personal computers, which were just beginning to emerge.

Their breakthrough came when IBM selected Microsoft to provide the operating system for the IBM Personal Computer (IBM PC), introduced in 1981. Microsoft acquired an operating system called QDOS (Quick and Dirty Operating System), modified it, and released it as MS-DOS (Microsoft Disk Operating System).

MS-DOS quickly became the dominant operating system for IBM-compatible computers.

Life Before Windows

Early personal computers were difficult to use.

Users interacted with the computer through a command-line interface, typing commands such as:

C:\> DIR
C:\> COPY
C:\> FORMAT

There were no icons, windows, or mouse controls.

Only users who memorized commands could operate computers efficiently.

As computers became more common, there was growing demand for a simpler, more visual interface.

The Birth of Windows

Microsoft answered this challenge with Windows 1.0, released on November 20, 1985.

Rather than replacing MS-DOS, Windows functioned as a graphical shell running on top of DOS.

It introduced several revolutionary features:

• Graphical windows
• Mouse support
• Icons
• Pull-down menus
• Scroll bars
• Multiple applications running simultaneously

Although primitive by today’s standards, Windows 1.0 marked the beginning of a new era.
