Are you a privacy-conscious person who wants to avoid tracking, telemetry, and data mining, an IT professional seeking customizable, robust, and free tools for system administration, or someone on a budget looking for the best free alternatives to software like Microsoft Office or Adobe Creative Cloud? Perhaps you need software to edit your photos, write and manage your documents, or improve your media playback experience. Then, open-source software is what you need.

Popular open source software examples, such as GIMP, LibreOffice, Shotcut, Audacity, and VLC Media Player, allow you to modify the software code to fit your needs. 

Additionally, the top open source software for PC is generally free, completely transparent, and highly customizable. They offer several advantages, such as easy integration with other applications and platforms. For example, LibreOffice seamlessly opens Microsoft Office files, ensuring compatibility and smooth workflow transitions, while VLC Media Player streams content effortlessly to devices like Chromecast, enhancing your multimedia experience.

Hence, this article lists the best open source software for Windows you can use for your various requirements, while first explaining the meaning of open source software. 

What Is Open Source Software 

Imagine a proprietary software (for example, Adobe Creative Cloud), i.e., a copyrighted software, which is the property of its creator or owner, that you cannot relicense, distribute, copy, or inspect the code yourself. Moreover, you can use this software only under predetermined conditions, which usually come for a fee. 

An open source software is the exact opposite. 

Built by multiple collaborators who voluntarily worked to create some awesome software, an open-source program is software with an open or publicly available code. 

This is a software operating under a license that contains distribution, modification, sublicensing, and other software permissions and limitations. 

The licenses under which open source software operates include the MIT license, the Apache 2.0 license, and the GNU GPL. 

An MIT license is the most popular open source software license that grants you the copyright license without granting a patent; you can use the software commercially. 

An Apache 2.0 license lets you use, distribute, and modify open source software without royalty payment or patent infringement. 

The GNU GPL license allows subsequent work on the open source software, but under the same terms. 

While this is what open source software means, is it a secure option? Let’s answer this question next. 

Are Open Source Software Secure 

Despite the public availability of the source code, an open-source program is often more secure than closed or proprietary software, as anyone can inspect the code and there is greater community collaboration. However, it’s important to acknowledge that open source software can also have vulnerabilities if not properly maintained. Fortunately, active communities play a crucial role in addressing these issues quickly, making the software more resilient over time.

That said, let’s proceed to the list of top open source software available currently.
