ReactOS 0.3.14 | 51 MB

ReactOS® is a free, modern operating system based on the design of Windows® XP/2003. Written completely from scratch, it aims to follow the Windows-NT® architecture designed by Microsoft from the hardware level right through to the application level. This is not a Linux based system, and shares none of the unix architecture.


The main goal of the ReactOS project is to provide an operating system which is binary compatible with Windows. This will allow your Windows applications and drivers to run as they would on your Windows system. Additionally, the look and feel of the Windows operating system is used, such that people accustomed to the familiar user interface of Windows® would find using ReactOS straightforward. The ultimate goal of ReactOS is to allow you to remove Windows® and install ReactOS without the end user noticing the change.


What is ReactOS?

ReactOS is a free and open-source operating system based on the Windows NT architecture, providing support for existing applications and drivers, and an alternative to the current dominant consumer and server operating systems.


Why re-implement NT? 

First of all, the 'Windows' the general public knows is actually just one part of the modern Windows NT operating system. They usually mean the Win32 subsystem, a layer that sits upon the NT kernel, providing the user and application interface. "NT is still around, known as XP and Vista"


Most people think of 'NT' as 'WinNT 4', while in reality the term NT refers to the NT series, which ranges from version 3 over NT5 (2000, XP, 2003) to NT6 (Vista, 2008 and 7).
The NTarchitecture was designed by a team lead by David Cutler, a former lead developer of VMS. It took them more than 4 years to combine the best of UNIX, VMS and OS/2 and create the NT architecture.



What about UNIX?


Mac OS X, Linux, BSD and other UNIX derivates share a common heritage based on a more than three decades old design of a simple basic operating system, that has evolved over time into a complex structure.
Modern incarnations like Mac OS X put a fancy graphical user interface on top of UNIX, to hide system details, but focus mainly on beginners, and many advanced users are left out in the rain, as most advanced features cannot be accessed from the graphical user interface. Almost all UNIX flavors retain some of the original design flaws and binary compatibility between various versions is usually non-existent.

In theory there are a few UNIX standards like POSIX but in practice the standards are old and cover only the basic operating system and the terminal environment. Other standards such as the Linux Standard Base are often not implemented faithfully. As there is no user interface standard nor a standard API, most people still have to use command line applications or fight through the GUI mess. Many UNIX derivates use the de-facto standard X-Window system for graphical output, which might well possess one of the worst designs in software history.
Still, modern UNIX derivates are trying to catch up with recent innovations and some of them already possess important features like access control list support.

In contrast to UNIX, ReactOS was designed for people familiar and comfortable with the Windows environment. Everything can be done through the well known Win32 user interface and advanced users are free to automate tasks with scripts or use the console.
Compatible "Change your OS, not your software!"


The ReactOS project reimplements a state-of-the-art and open NT-like operating system based on the NT architecture. It comes with a WIN32 subsystem, NT driver compatibility and a handful of useful applications and tools.

ReactOS combines the power and strengths of the NT kernel - which is well known for its extensibility, portability, reliability, robustness, performance and compatibility – with Win32 compatibility.
Secure

Despite statements to the contrary, NT is secure by design. It was the first mainstream operating system with a proper implementation of a very flexible security model based on access control lists.

Recent NT-based operating systems from Redmond, especially XP, got a bad reputation for their weak default security settings; mainly to simplify the transition from Win9x for both users and legacy applications. This decision alone invalidated many of the security features in NT. ReactOS will incorporate proper default security settings.

ReactOS has been designed for high security; it doesn't share some of the common security flaws with other operating systems.

On a closer view, real computer viruses (which are normal applications) are not as widespread anymore. Most malicious applications are scripts that target common network software like browsers and email applications and software with built-in scripting support like various Office products.
Obviously, more widespread systems with a large user base are more likely to be attacked by bad software writers than minor systems like Macintosh and Linux.
Lightweight

In short, ReactOS is designed to be powerful and lightweight. You can think of the term "lightweight" in the good old fashion of Win95, a consistent user interface and small bundle of very common and useful tools. Although lightweight, ReactOS offers a lot in comparison to Windows 95, with an up-to-date experience as well as built from scratch on a rock solid NT core.
