History Of Windows Operating System

To run a computer and interact with other devices like keyboard, mouse, LAN card, Modem, Pen drive, printer, scanner we need an Operating System. Only with the help of the operating system, the computer can be able to understand our given instructions.

In simple words, without any operating system computer was unable to interact with users. The OS keeps data from every computer program in itself. With which the operating system only decides which time the program will use for which resources.

There are different types of OS available in the market but the most user-friendly of them is the Windows Operating system. Today a large amount of market share hold by Windows OS.

People of different ages find it very useful because it is easy to use. There are lots of services available in Windows by default and you can try these with no prior knowledge needed. Over the last 36 years, Windows’s been modified so beautifully and integrated all the latest technologies as per the need of a user.

So in this article, we explore the history of the window’s operating system.

How This was Started?

Bill gates and paul Allen

Two Childhood Friends Paul Allen and Bill Gates who are programmers and fond of technology and software are busy with their experiments. In 1974, the first personal computer kit (the Altair 8800) was launched by Micro Instrumentation and Telemetry Systems (MITS) in Albuquerque, New Mexico. Gates and Allen contacted the president of MITS (Ed Roberts) and offered to develop the first microcomputer in the form of BASIC (originally developed by John Kemeny and Thomas Kurtz) to extend the performance of the 8800.

After, this successful Development of Altair Basic they both joined MITS. But within a short period in 1979 Bill and Allen created a company initially Called “Micro-Soft”. Microsoft brought an existing Operating system from Seattle Computer Products (86-DOS), for $75,000 in 1981. The same year IBM launched its personal computer using Microsoft’s new operating system, MS-DOS 1.0.

They both invented this Disk Operating System. DOS primarily relied on a set of commands to interact with the computer, and at that time, was considered as a future-ready system that had its right use. On November 10, 1983, Microsoft formally announced a Graphical User interface (GUI) for its own OS MS-DOS called Microsoft Windows.

Initially, the new product was developed under the name Interface Manager, but before the official introduction in 1985, the marketing gurus convinced Bill Gates, that Windows is a more suitable name.

The main partner of Microsoft since 1981 was IBM when MS-DOS became the highly successful operating system, that came bundled with an IBM computer.

Early Days before Windows came!

In the year 1983, initially, bill gates approached IBM to launch a beta version of the operating system with no graphic user interface in it. DOS(Disk Operating System) OS that runs through commands, But at that time IBM was working with their OS called ‘Top View‘ so gates had to wait for some time. In the meantime, Apple launched two operating systems called Lisa and Macintosh with GUI (Graphic User Interface) built within it. Suddenly gates realize the importance of GUI and work on that for more than two years. After doing all the modifications and integration with DOS finally, Microsoft launched its first OS in the year 1985 in the name of Windows 1.0. If you want detailed info regarding OS then Check out the History.

The Journey From 1.0 to 10:

The journey of windows is quite fascinating because when it’s released in 1985 it’s not perfect and supports a very limited amount of function. But in these 36 years, windows evolve wonderfully and create one of the major brands in the operating system industry. They have fully developed their OS based on what customers want’s, and that’s the main reason for their huge success.

So lest discuss all versions of the windows one by one…

Windows 1.0 (1985):


The first version of window’s MS-DOS is called the Microsoft disk operating system which is a character-based operating system. First OS from Microsoft support input device like Mouse, Keyboard. By moving a mouse pointer, the user can navigate through the screen and click icons to carry out specific tasks.

The first OS supports 16-bit multitasking so a user can do multiple works at a time like doing a calculation and taking notes simultaneously. Most of the user is unfamiliar with a mouse so Microsoft builds a game for them called Reversi(visible in the screenshot) which help a user to practice the cursor of the mouse and familiar with the click function.

Windows 2.0:


Microsoft introduced Windows 2.0 in the year 1987 and supports the Intel 286 (16 Bit) processor. This version added desktop icons, keyboard shortcuts, and improved graphics support.

Windows 2.0 was more reliable and faster than Windows 1, designed with improved screen layout control. The first time Microsoft introduced Microsoft Word and Excel for Windows and is used by many immediately.

The big innovation for Windows 2 was that windows could overlap each other, and it also introduced the ability to minimize or maximize windows instead of opening a window by clicking or zooming an icon.

The control panel, where various system settings and configuration options were collected together in one place, was introduced in Windows 2 and is still very much useful.

Windows 3.0:


In the year 1990 Microsoft released their Windows 3.0 OS which is a much more improved version in terms of performance. This is the first OS that supports a dedicated hard drive and runs on Intel 386 processor.

The release of Microsoft’s SDK (Software Development Kit) with Windows 3.0 enables software developers to focus more on writing applications increases the development of new programs for both business and personal use.

It can run MS-DOS programs means we run programs from the command prompt window.

In 1992 Microsoft released version 3.1 with the features like true type fonts, rich multimedia support, object linking and embedding (OLE), application reboot capability.

This is the first time window’s version comes with a Program manager, file manager, and print manager. We run different programs outside the default ones with the help of a program manager which attracts many developers to develop applications for windows.

The introduction of virtual memory and 16 color support help the OS to run applications more smoothly and efficiently. We could run multiple programs with much-improved accuracy.

The introduction of Hearts, Minesweeper, and Solitaire increase the importance of personal computers.

Windows NT (New Technology):


On July 27, 1993, Microsoft release new technology specially designed for server and high-end multitasking environments. It had 32-bit multiple processor support and was created for higher security and stability.

There are two versions of Windows NT: Windows NT Server, designed to act as a server in networks, and Windows NT Workstation for stand-alone or client workstations.

Due to its lack of hardware support and complexity developers are not interested to migrate their computers to NT, that’s why it creates a small impact on the market.

Windows 95:


For the first time, Microsoft created an operating system that is run independently with the window’s kernel (A ‘kernel’ is an interface between the software and hardware, taking program demands and allocating them between the requisite hardware components, such as the CPU, RAM and Input/Output devices (keyboards, mice, printers, display, etc.) but still based on MS-DOS kernel.

A significant change in the user interfaces with the Start menu and taskbar which is very appealing for users. It introduced preemptive multitasking into the operating system which was a way to ensure that each application gets a fair portion of the CPU while it’s trying to run. Creates a stable system.

It also introduced the concept of “Plug and Play” to connect a peripheral and the operating system finds the appropriate drivers for it and makes it work. Supports different CD- ROM devices.

Windows 95 also introduced a 32-bit environment, the taskbar where all the opened apps are minimized, a start button for accessing the applications, Recycle bin where all the deleted data is stored. It allows us to write the name of the file with 255 characters along with mixed cases (upper and lower case both).

An Internet Explorer was also introduced with version 95 plus version (OSR2) later because of the increasing trends of internet surfing.

Other miscellaneous abilities added in Windows 95 are built-in dial-up networking for the Internet, improved multimedia capability, simpler installation of software and hardware, and improved networking and mobile computing service.

Windows 98:


Released in June 1998, Windows 98 is the last version to be based on MS-DOS. It focuses on home and office-based PCs.

Windows 98 was built on Windows 95 and brought on IE(Internet Explorer) version 4, Outlook Express, Windows Address Book, Microsoft Chat, and NetShow Player, which was replaced by the windows media player later in 1999.

One of the biggest changes was the introduction of the Windows Driver Model for computer components and accessories – one driver to support all future versions of Windows.

Users could find all the information on the local computer as well as on the internet easily because of the internet connection sharing feature.

Other useful features integrated like improved power management system (Hibernate and standby added), network management where configure an internal or external network, USB management including USB hub and USB mice.

Windows 2000,(Win 2K):

On 17th February 2000, Microsoft released Windows 2000, which is an upgrade from NT 4.0 series. Although it included all the functionality from the 98 and NT like improved Internet explorer browser, Outlook express, run multiple programs simultaneously, able to access files over the internet, access printers, etc.

Microsoft released four versions of Windows 2000, which are Professional, Server, Advanced Server, and Datacenter Server edition.

Some features like NTFS (New Technology File System) 3.0, Microsoft Management Console (MMC), Encryption File System (EFS), Active Directory (AD) are introduced with Win2K edition.

The Automatic Update feature fully works with Win 2000, and also for the first time Microsoft integrate Hibernate function. In Hibernate the hardware of the computer remains in an inactive state to save power and resource.

There are also some new technologies integrated that help visually challenged people.

Windows ME(Millennium Edition):

In the short span of four months, another edition called windows me launched on June 19, 2000, with multimedia and networking enhancements for home users.

Windows ME introduced system restore and system file protection and auto-update features to create a stable and secure system. However, this edition was heavily criticized for its slow and buggy nature and not being able to create an impact in the market.

That’s why Microsoft replaced this one with their XP edition in the next year and solved all the issues.

  1. Thank you very much for sharing the history of the Windows Operating System. I’ve briefly touched the Windows 98 when I was a kid. I still remember how hard it is to operate it, but I love to play with Microsoft Word and Excel. Fast forward, I agree that Windows 10 is currently the best one and glad they didn’t reuse the UI of Windows 8 that much. By the way, I heard Windows 10 is the last and final Windows. Why they don’t want to create, for example, Windows 20?

    1. You welcome and let me inform you Windows 11 is coming in June 24 with lot’s of new features. We never know maybe one day Windows 20 came.
