The 15 Best Windows Alternative As Open Source OS in 2020

There is not a single person in the digital world who doesn’t know about the Windows OS. It is the most common and useful operating system for a computer. But with features, it costs a massive amount of money, and it takes an ample space in the PC’s storage. That is a problem when the world is offering information and services for free. And most importantly, the technology enthusiasts do not like to be bound by the restriction of a closed operating system like the Windows OS. That’s why the world has developed codes to create an open-source OS, free for everyone to use and modified as per anyone’s desire and taste. In today’s article, we will know about 15 of the Best Windows Alternative Open Source OS. So, let’s get ahead on the topic.

What is an Operating System?


Operating System or OS is a computer system or software that manages and handles the computer’s hardware, software resources, and yields other computer programs and services. You can say it is the brain of a PC that runs the whole operation. Without an OS, your PC won’t even turn on or let you do anything. You can have all the best hardware loaded in your PC, but your PC will be nothing but an empty metal shell without an OS software.

Depending on the source code there are mainly two types of OS,

  1. Open source Operating System and;
  2. Closed source Operating System.

The most commonly used operating systems for computers are Microsoft Windows, macOS, and Linux. The first two are the example of a closed source Operating System, and the later one is an open-source Operating System.

The Early History of the Operating Systems


The operating system was first developed in the early 1950s. The first operating system was invented in 1964 by IBM to operate IBM’s mainframe computer. And the first PC (IBM Model 5150) for general use came with Microsoft’s first operating system, ‘MS-DOS’, in 1981. MS-DOS was a closed source OS.

It was Richard Stallman who started the Open Source movement in 1976, and the ‘Emacs’ project was the first Open Source Operating Systems.

Famous ‘Linux OS’ started its journey in 1991, and ‘MacOS’ was initially released on March 24, 2001.

What is Windows Operating System?


The first windows OS was ‘Windows 1.0’, which was released 34 years ago on November 20, 1985. It has come a long way till then. Windows is a series of operating systems created and developed by Microsoft Corporation. In 1993 Microsoft published ‘Windows NT 3.1,’ which was the first business-oriented version of Windows OS. Windows 10 is the latest version of Windows that is currently ruling the OS market. You can efficiently productively use Windows 10. This is proof that Windows has developed dramatically over the years.

What is an Open Source Operating System?


Open Source Operating System is an operating system the source code of which is relapsed to the public under the Open Source License. The licenses might be restrictive like the GPL that allows the user to use, modify, remove, edit, distribute the system. You can modify an Open Source Operating System and make it available to the public for general use. An Open Source OS is free. You do not have to pay any money to the developer, and you cannot charge money for the OS you modified. As it is free and available for the mass that ensures the OS is never out of developers, and it continues to develop. Some examples of Open Source Operating Systems are Linux, FreeBSD, Dragonfly BSD, etc. There are some IoT (Internet of Things) operating systems that are open source too.

How Do Open-Source Applications Work?


An Open Source Operating System’s functionality and coding are the same as the proprietary applications or a closed Source Operating System. The difference is that it is available for everyone to use, inspect, and modify the OS. 

Difference Between Windows OS and Open Source OS?


  • Cost: The windows OS costs from $90 to $121, but an Open Source Operating Systems is free of cost.
  • Development of the OS: an Open Source Operating Systems is accessible by anyone because the development of the OS is unique and continues. But for the Windows OS, only the Microsoft Corporation develops the system. We are making it a little bit backdated compared to the Open Source System.
  • Source Availability: Windows OS’s Source is only available to Microsoft. You only pay to use the OS, but you don’t own the system software. But in the case of the open-source OS, the source is available for anyone to grab.
  • Flexibility: Its users cannot modify the Windows operating system. But the open-source operating system is much more flexible. Anyone with the knowledge of coding and C language can modify the system as he desires or needs.
  • Licensing: the Windows OS is under and protected by Microsoft License. But every Open Source Operating Systems is under Open-source license.
  • Security: Some Open Source Operating Systems is much more secure from hacks, malware, and other threats than the Windows OS.
