Should you stay away from proprietary operating systems?

Should you stay away from proprietary operating systems?

Closed source software is a third-party product that uses a source code that has not been released to the public, and does not include the option to share the source code with anyone, as no one is can see it or change it. the organization that sells its software to others because it cannot be changed, or copied. A closed source software approach provides organizations with greater control over their user experience and brand message. , because their software is not open to the public, nor is it free.

What is closed source software?

Closed source code is a non-free program, where the source code is protected and encrypted unlike open source software, if you use closed source software, you will not be able to copy, modify or delete parts of it. code, and closed only Software developers can handle source code, and make software upgrades and repairs.

Closed source software cannot be widely distributed because of the license that protects it. Examples of closed source software include Windows and Microsoft Office.

Do you have to stay away from proprietary operating systems?

Choosing the best type of software, whether closed or open source, depends on the needs and goals of your business, so the answer to this question is ultimately in but we would like to point out that only the creators of closed source software are working to make improvements and repairs to their software, which means that continuous development is in their hands only, while updating and Open source software development is based on comprehensive cooperation, and as a result development and repair usually continue indefinitely because the source code is available to all users.

Open source software has a strong advantage that makes it better than closed source, meaning that it is continuous forever, unlike closed source software which can stop working at any time the manufacturer wants. As for open source software, you can get updates, features, or fix new longevity.

Disadvantages of Closed Source Software

Customers have little control over security issues.

Customers rely on updates from the manufacturer even when there are serious security vulnerabilities.

Closed source software makes customers solely dependent on the manufacturer.

Customers have to pay to modify the program according to their own needs.

The difference between closed source and open source software

The concept of closed source software contrasts with open source, in the case of open source software, anyone can view the source code and modify it completely freely, which means that anyone with experience will be able to understand how this program works in detail, so they will be able to modify the code, or Complete its shortcomings in order to create a modified version of the software that is better suited to specific use cases, and is also allowed to publish such changes.

This is not possible with proprietary software (closed source). The source code can only be modified by its creator or authorized person, who are the only ones who can access and modify it, and the manufacturer of the Closed source software charges a fee to modify the program according to the needs of each user.

Open source software is often free, or relatively low-cost, and you can use it completely freely, and closed source software manufacturers sell products to customers for use only in scope. of the terms of the license.


The security of closed source and open source software is controversial because they both have their advantages and disadvantages. You can view, share and modify open source code, which means anyone can fix, update and test the faulty code, how the security flaw is fixed It's super fast, and the code it is carefully checked after each release, although since the source code is open, hackers will be able to practice with it.

Conversely, closed source software can only be fixed by the manufacturer, if something goes wrong with the software you will have to send a request, and wait for a response from the support team, and it may take longer to solves the problem compared to open source, but when it comes to choosing the most secure software, the answer is that both have advantages and disadvantages.

quality support

By comparing the support between open source and closed source programs, we find that the closed source is the winner, as it will get permanent support at any time, and the response will be organized, and documented. well, as for open source programs, such an option is not provided, the only support options there are forums, articles, and expert opinions.

Source code availability

Open source software provides the ability to change source code without any restrictions. Users can develop whatever they want, take advantage of innovations developed by others within the user community, and since the source code is easily accessible, software developers can improve their performance. existing software.

Closed source software is more restrictive than open source software because the source code cannot be changed, or displayed, however this restriction may contribute to the security and reliability of the software. of the closed source.

The most famous examples of closed source software

Most common operating systems, databases, applications, and programs available today are closed source. Examples of closed source software include:

Microsoft Windows

It is a graphical operating system produced by Microsoft, which dominates the market for personal and desktop computers in the world, with a market share of more than 90 percent, which outperforms operating systems such as Mac, and The latest version of Windows is Windows 11, and the latest version for servers is Windows Server 2022.


This is a closed source communication application that allows people to communicate with each other through voice and video calls using mobile devices, computers or tablets.


It is a closed source computer protection program that has many features such as antivirus protection, threat scans, browser protection, and so on.

Microsoft Office

It is a closed source software that includes many applications that are used to perform specific tasks, for example Microsoft Word for creating text documents, PowerPoint for presentations, Microsoft Outlook for emails, Microsoft Excel for spreadsheets, and so on.

Adobe reader

This software helps people perform complex tasks such as editing and signing PDF files, annotating them, and has other functions, including opening PDF files and converting Word documents to PDF, and is a closed source software.
