icrosoft is mostly criticized by the Linux community for their closed-source Windows operating system which single-handedly outperforms the popularity of all the Linux distros combined. The company has been an advocate of proprietary software, but in the last couple of years, Redmond has made a lot of contributions to the open source community.

Microsoft is now one of the top-tier members of the Linux Foundation and has a regular presence on GitHub. Stuffing distros such as Ubuntu, openSUSE, and Fedora into the Windows Subsystem is the sign of love Microsoft is showing towards the Linux community.

However, on the other hand, some people might want to tie this with Microsoft’s evil intentions. Earlier, it was predicted that they would digest Linux in the long run. If Windows becomes capable of running Linux applications someday, then people might fall for it.

Leaving all these things aside, one important thing to consider is that various free and open-source software available for Windows 10. If you want to take advantage of Windows 10’s fluidity and other features, you can do so with a touch of open source.

Don’t forget to check out our list of open source apps for Android.

14 Best Free Open Source Software For Windows 10

Developed by Mozilla Foundation, Firefox is an open-source web browser which was first released in 2002. Firefox started to lose its user base after the arrival of Google Chrome in 2009.

Firefox is the default web browser on various Linux distributions, but it also has gigantic user based on the Windows platform, and not to mention Android.

2. Chromium – Open source alternative to Edge

People often criticize Google Chrome for its proprietary nature; its daddy Chromium is always ready to rescue the popular browser with its open source goodies. In fact, Chrome borrows its base code from Chromium after which Google makes some changes.

One of the advantages of having Chrome or Chromium is that you can stream content from your desktop to TV screen using a Chromecast receiver.

Chromium has posed itself as a serious contender for the default web browser on Linux systems. When it comes to Windows 10, many people are stuck to Chrome, but Chromium can be a great alternative if you want to fill your proprietary machine with some open source software.

Tor Browser is the perfect solution for users who don’t want to blow their anonymity cover on the internet. The open-source web browser for Windows 10, macOS, and Linux leverages Tor network to conceal user’s identity and IP address.

The file-sharing software FileZilla is also a great open source software for Windows 10. It’s available for Linux and macOS as well. The FTP client was born as a class project of a student trio in 2001.

FileZilla offers protected file sharing which requires a username and password to access the shared data. Overall, the software has received a positive response, but it has been accused of storing passwords insecurely. Users have criticized FileZilla for bundling adware as a part of SourceForge’s revenue program.

12. Mozilla Thunderbird – Open source alternative to Outlook

Thunderbird is an email client developed by Mozilla. Launched in 2004, it was able to serve the rising demand for a dedicated email client. In the last few years, Mozilla has reduced their focus on Thunderbird because they don’t believe it can make the same the industry-wide impact as Firefox does.

The open source email client is available for Windows 10, Linux, and MacOS. Other than an email client, Thunderbird includes a Calendar, Chat client, and can receive RSS feeds amongst various other features. However, the emails are listed in a congested manner and might ruin your user experience.

13. Media Player Classic – Home Cinema (MPC-HC)

MPC-HC is also an open source media player for Windows 10. In terms of video and audio format support, it can easily go shoulder to shoulder with VLC. One thing I like about MPC-HC is that it can play 4K videos if you’re running capable hardware.

The biggest drawback of MPC-HC is that it’s only available for Windows platforms, that’s where VLC takes over by providing a cross-platform media player.

Download MPC-HC
