ReactOS in Action - Free and Open Source Windows for All

ReactOS® is a free open source operating system based on the best design principles found in the Windows NT® architecture (Windows versions such as Windows XP, Windows 7, Windows Server 2012 are built on Windows NT architecture). Written completely from scratch, ReactOS is not a Linux based system, and shares none of the UNIX architecture.
