"Easy-to-Use, Lightweight Windows-Like OS with Great Driver Compatibility"
What do you like best about ReactOS?

ReactOS is an open-source operating system. It’s easy to download and install, and its graphics feel very similar to Windows. It can run Windows executable files and apps, and it has an old-school Windows look from the early 2000s, like Windows XP.

Overall, it’s very user-friendly and easy to use and understand, without demanding high system resources. It’s also highly compatible with Windows drivers and can be used to run older, classic Windows applications. It doesn’t require much hardware, and technically it can be an alternative to the modern Windows 11 look if you want a more classic Windows-like experience.

It’s easy and convenient to use, not resource-hungry, and it works very easily in VirtualBox as well. The version I used felt stable, and I can see it being used as an everyday OS. Review collected by and hosted on G2.com.

What do you dislike about ReactOS?

React OS is good, but because it uses an old Windows-style look and graphics, it sometimes feels like an outdated experience. At times, these older visuals make it less attractive, and I don’t feel like spending a lot of time using React OS. It also has some limitations, and the settings can be hard to access; they aren’t very straightforward, so it’s not easy to set up the proper environment for use. Sometimes it becomes unresponsive or lags, and it can feel unstable and buggy.

It also has a very unpopular GUI similar to Windows NT, which, in my opinion, isn’t very appealing to users today. Review collected by and hosted on G2.com.

"A Lightweight Open-Source Platform for Windows-Compatible Legacy Software"
What do you like best about ReactOS?

What I like best about ReactOS is its goal of being fully compatible with Windows applications and drivers while remaining open-source and lightweight. It offers a familiar Windows-like environment without licensing costs, gives transparency and control over the OS, and is especially useful for learning, experimentation, and running legacy software on modest hardware. Review collected by and hosted on G2.com.

What do you dislike about ReactOS?

What I dislike about ReactOS is that it is still in an early development stage, which means stability issues, incomplete hardware driver support, and limited compatibility with some modern Windows applications. Bugs and crashes can occur, documentation is sometimes sparse, and it is not yet suitable for daily production use. As a result, it works better as an experimental or educational system than a reliable everyday OS. Review collected by and hosted on G2.com.

"Open-Source Windows Compatibility in a Lightweight, Familiar Environment"
What do you like best about ReactOS?

The best thing about ReactOS is its vision to provide Windows application and driver compatibility while being completely open source. It allows users to explore a familiar Windows-like environment without licensing costs. Its lightweight nature and open codebase make it very useful for learning, experimentation, and testing legacy applications. Review collected by and hosted on G2.com.

What do you dislike about ReactOS?

ReactOS is still in an early development stage, which makes it unreliable for daily or production use. Many features are incomplete, system stability can be an issue, and hardware and driver support is limited. The community support and documentation are helpful but not yet as mature as other operating systems. Review collected by and hosted on G2.com.

"Revives Legacy Applications with Ease"
What do you like best about ReactOS?

I appreciate ReactOS for its valuable role in providing real-world learning tools for developers interested in understanding the Windows kernel. For six months, I have found it particularly helpful in running older applications and for evaluation and testing purposes. I love its capability to use FAT16 or 32 for boot partitions, which aligns well with my testing needs. Moreover, ReactOS bridges the gap by running older applications that aren't backward compatible with other operating systems, which includes my usage of DOSBox. The performance of these applications on ReactOS impresses me, running smoother compared to other platforms. ReactOS is not hardware intensive, which is beneficial as it extends the life of aging systems and repurposes outdated hardware. I like the familiar Windows interface which makes it user-friendly and less intimidating. Additionally, the fast boot process is a feature I find appealing too. The straightforward setup and the ability for quick installation further enhance its user-friendly nature, making the experience pleasant and efficient overall.

What do you dislike about ReactOS?

I find the lack of NTFS support in ReactOS a limitation. It prevents me from using larger drives efficiently, which could enhance my experience significantly by allowing better utilization of storage resources and handling of larger files. Review collected by and hosted on G2.com.
