ReactOS online running, a free and open-source operating system based on the best design principles found in the Windows NT architecture. Written completely from scratch, ReactOS is not a Linux-based system and it 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 Windows applications and drivers to run as they would on a 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 people to use it as an alternative to Windows without the need to change software they are used to.

The ReactOS operating system design is able
to provide portability across families of
processors, such as Intel x86 and even
provide portability across different processor
architectures, such as CISC and RISC. There
is only one single OS core, the kernel; porting
ReactOS to other architectures only involves
porting the hardware abstraction layer, the
lowest part that talks directly with the
platform hardware.

ReactOS is flexible and extensible by design.
ReactOS is probably one of the most versatile
operating system platform, especially thanks
to its NT kernel and the open source nature.
ReactOS can be extended with the help of so
called "subsystems" to provide support for
legacy applications from other platforms. For
example, a POSIX subsystem would provide
compatibility layer with various flavors of
UNIX applications.

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.

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.

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.
