ReactOS User Interface

ReactOS is an open source operating system by the ReactOS Foundation. Unlike Unix-like operating systems, ReactOS re-implements the NT architecture and Windows API as a standalone OS. Its goal is to reach program and driver compatibility with Windows. As of 2017, the support level is on par with Windows Server 2003 SP2.

This article only covers major releases and includes Nightly Builds.

Development

In 1996, a group formed under the name FreeWin95 with the intention of making an open source Windows 95 clone. Development on FreeWin95 halted soon after, as source code contributions never materialized. After a short hiatus, the group reformed in 1998 and changed the project's name to ReactOS. Most development is made gradually, with releases set every 2-6 months. A version number is assigned to major releases (such as 0.4.6), while nightly builds and source code builds use their commit number instead.

Current state

ReactOS is still considered alpha-quality software and only recommended for evaluation and testing purposes. Installation, hardware detection, booting, and running programs can suffer from bugs. As the operating system is open source, it can be freely built from source code, or downloaded from the nightly builds website.

Virtualization support exists for QEMU, however, it can run on other hypervisors. It's possible to install ReactOS on a physical machine, however, this configuration can be risky.

ReactOS 0.4

ReactOS 0.4.0 is rumored to be released in Holidays 2015, it's possible to download a nightly build from the ReactOS website though. It will bring many new features, the major ones being a new Explorer and Application Manager. ReactOS 0.4 will also improve sound, Wi-Fi and USB support.
