ReactOS is an operating system. Our own main features are that ReactOS is able to run Windows software, and it is also able to run Windows drivers. ReactOS looks-like Windows, and it is free and open source. ReactOS is a free and open source operating system written from scratch. Its design is based on Windows in the same way Linux is based on Unix, however ReactOS is not Linux. ReactOS looks and feels like Windows, is able to your run all your Windows applications and software, as well as all your Windows drivers, and is familiar to Windows users. You can create your own ReactOS versions! You’re using Open Source software daily if you use Firefox, LibreOffice, OpenOffice, GNU-Linux distributions among zillions of Open Source projects out there. The Open Source projects, as ReactOS, are driven for and by its Community, so being active translating, donating, or coding is a way to help ReactOS boost forward.
