Episode fifteen of the series tells the story of how Microsoft Windows evolved from a simple graphical add-on for MS-DOS into a global standard that transformed the way people worked with personal computers. Here we follow the system’s development from version 1.0, through the breakthrough “threes,” to the NT family and the era of Windows 2000.
1. Windows 1.0–3.x – the Birth of the “Windows”
Windows 1.0 was released on November 20, 1985 as a graphical shell on top of MS-DOS.
- Tiled windows (they could not overlap!), mouse support (a novelty!), Calculator, Notepad, Paint, a basic file manager.
- The success was moderate — most software was still text-based.
Windows 2.0 (1987):
- Overlapping windows, support for graphical Word and Excel, keyboard shortcuts.
Windows 3.0 (May 1990):
- A real breakthrough — cooperative multitasking, stability, a new VGA GUI, Real/Standard/386 Enhanced modes.
- Popular in offices and homes, with a huge library of applications.
Windows 3.1/3.11 (1992–93):
- TrueType fonts, networking support, multimedia features, a growing OEM software marketplace.

- Iconic Start Menu, Taskbar, preemptive 32-bit multitasking, Plug & Play support
- Full networking support, TCP/IP out of the box, Internet Explorer

3. Windows NT, 2000 – from Desktop to Server Rooms
Windows NT 3.1 (1993):
- A completely new kernel, 32-bit codebase, memory protection, strong security
- Workstation and Server editions, Win32 API
Windows NT 4.0 (1996):
- Brought the Windows 95 interface to the NT line
Windows 2000:
- Stability, Active Directory, Plug & Play support, multiprocessor capabilities
- The direct predecessor of Windows XP
| Version | Years | Key Features |
|---|---|---|
| Windows 1.x/2.x | 1985–1990 | DOS shell, windows, mouse |
| Windows 3.x | 1990–1993 | VGA GUI, multitasking, applications |
| Windows 9x | 1995–2000 | 32-bit GUI, Plug & Play, USB |
| Windows NT/2000 | 1993–2001 | Stability, security, networking |
4. Impact on the Market and Users
- Windows gradually replaced DOS, GEM, OS/2 and other PC operating systems.
- It became the standard in homes, administration, education and industry.
- It opened the way to the Internet, multitasking, and gaming (DirectX, WinAPI).
- The OEM licensing model bundled Windows with nearly every PC or laptop sold.
5. Legacy
Windows defined the model of graphical work on the PC, popularized the mouse, keyboard shortcuts and the GUI as the foundation of productivity.
To this day, later versions — XP, 7, 10, 11 — remain direct descendants of concepts introduced back in the 3.x era and Windows 95.
