Success Story Behind Windows from MS-DOS to Windows 10


After 35 years from their initial launch, Microsoft had become the most popular operating system in the world. From generation to generation they developed their OS to give a better experience to the users and there are a lot of incidents behind the success story of Windows from MS-DOS to Windows 10 which we are using now. Did you ever know that Bill Gates is not the person who created the DOS(Disk Operating System) operating system? If not let’s see the Success Story Behind Windows from MS-DOS to Windows 10

History of Microsoft

It almost 35 years, 1985 November 20 is the very first launch date of the MS-DOS operating system. Before creating this MS-DOS, Let’s see the background story of Bill Gates and his friends. In 1968, Teletype Model 32 computers were brought into Bill’s school and this Teletype Model 32 is more like a typewriter, and Computer Center Cooperation were the owners. To use this Teletype 32 for one hour, they had to pay 40 dollars to the owners but Bill and three of his friends including Paul Allen figured out a way to use these computers without paying. However, after some time, the company figured out this and they decide to ban Bill and his friends from using computers.

Bill was just 14 years old, and after this incident, they created a club called “Lakeside Computer Club” with the purpose of troubleshooting the errors and fixing them with their programming knowledge. But the coolest thing is, the first customer of this Lakeside Computer Club is the same company which bans Bill and his friends, the Computer Center Cooperation. After 3 years Bill and his friend Allen started a company called “Traf-O-Data” to create a software solution to convert traffic data into readable data. But after selecting into different universities both of them stepped out of the company and started continuing higher studies.

During the 1975 – 1980 time period, the market slowly changed to focus on minicomputers and microcomputers. But all the big companies including IBM had a huge doubt about creating a computer for personal use as it cost around 20,000 dollars or even more and they didn’t have any idea whether it will be profitable or not. But in 1975, MIT created ALTAIR 8800 PC model was released and this made a huge revolution in PC history. Everyone started about talking this ALTAIR 8800 which has a simple interface with switches and bulbs. Again in 1975, Bill and his friend Allen came up with an idea of creating software(a basic interpreter) for this ALTAIR 8800 but none of them had an ALTAIR 8800 to test this.

Bill Gates decided to tell his first lie to MIT, saying that they almost developed an interpreter for ALTAIR 8800 and they are ready to give a demo version of that. Finally, MIT gave a chance for an interview and before the interview, Bill Gates and Paul Allen created an emulator on the mainframe computer at Harvard University to emulate as an ALTAIR 8800. With this successful attempt, 4KB paper tape code was taken to the MIT and this is the first successful software solution from Micro Computer Solutions which later became Microsoft with the contribution of Bill Gates and Paul Allen. This project generated over 30 Million for Microsoft.

The Story Of Microsoft DOS

After realizing the popularity of personal computers, IBM wanted to enter the microcomputer marketplace instead of staying in the first place. But as an additional item, IBM wanted to release their own operating system with their microcomputers. Among several DIY operating system projects, CPM(Control Program for Microcomputers) created by Digital Research Ink was the most popular one. IBM discussed with Digital Research Ink but they gave a high demand and refused to offer their operating system for IBM.

After this discussion, IBM contacted Bill Gates and asked to create an operating system for their latest PC. By that time, Tim Paterson who worked for Seattle Computer Products reverse engineered this CPM operating system and created a clone version after looking at the manual issued with CPM. Bill purchased this 86 DOS operating system from Tim Paterson for 75,000$ and joined him at Microsoft. After a quick development, MS-DOS was released for IBM microcomputers. This became the turning point of Microsoft and they successfully established their territory in the technical industry.

Moreover that Microsft gave their OS for more than 75 computers in micro pc manufacturing companies. After this release, Digital Research Ink was agreed to give their CPM OS to use in IBM computers but it was too late. And they had proof to show that MS-DOS was a clone from their CPM but they didn’t claim any copyrights and this was another significant moment for Microsoft.

Microsoft Contribution for Apple Macintosh

To prepare some Softwares for the Apple Macintosh, Bill Gates was invited and successfully contributed himself to development. Later in 1984, Apple Macintosh was released and Bill Gates also featured inside a video clip which they used as a trailer by that time. But later Apple claimed that Microsoft stole their GUI Design. In 1985 November 20, Microsoft released their Next Operating System Windows 1.0


Story from Windows 1.0 to Windows 10

  • Windows 1.0 – Graphical user interface created over MS-DOS which gave the facility to control applications with a mouse and more applications such as paint, clock, calendar, and a bunch of other stuff were added.
  • Windows 2.0 – Improved more than Windows 1.0 and added more features such as Resizing windows, optimizations for Intel’s brand new processor.
  • Windows 3 & 3.1 – Got the Ture Time Font which used in Apple macintosh in the year 1984.
  • Windows NT – Windows NT stands for Windows New Technology and mainly focused on cooperating, business-side users
  • Windows 95 – Going away from the MS-DOS-based architecture, Windows 95 was the first native 32-bit operating system. Fully designed Icons, Start Menus and User-friendly GUI were there and Microsoft dedicated a 30 Million budget for the development of Windows 95. Sold 1 million copies in 4 days and over 7 million copies were sold around worldwide within one month.
  • Windows 98 – Improved more than Windows 95 and added USB support.
  • Windows ME – First unsuccessful edition with bugs that cause blue screens and system slowdowns.
  • Windows 2000 – Designed and focused on the cooperate sector
  • Windows XP – Most popular operating system and became the next greatest hit after Windows 95. The only operating system which got official support over 14 years.
  • Windows Vista – Needed more RAM and powerful graphic cards to power up this OS. Unnecessary security features were added which make the users fed up with the OS
  • Windows 7 – Solid and stable OS to give an ultimate user experience
  • Windows 8 & 8.1 – Going away with the typical interface, a Tile complex interface was added but many people didn’t switch to this. As a solution, Windows 8.1 was released and added many missing features in Windows 8
  • Windows 10 – Final operating system from Microsoft. Security and more features will be given through updates

Microsoft is no longer willing to earn from selling their OS. Instead of that they are developing cloud services, Xbox game consoles and Apps which generates more income to them. This is the great Success Story Behind Windows from MS-DOS to Windows 10.
