ReactOS
An open-source operating system designed to achieve binary compatibility with Windows NT.
Timeline (last 90 days)
The ReactOS project took 25 years to clone Windows.
ReactOS is a free and open-source operating system aimed at achieving binary compatibility with Windows NT.
ReactOS as a whole remains in the Alpha stage.
ReactOS's user-mode components (such as user32.dll, kernel32.dll, and gdi32.dll) heavily reuse code from the Wine project.
ReactOS released version 0.4.16.
ReactOS uses the open-source ACPICA library to handle ACPI table parsing.
ReactOS currently relies primarily on the open-source Mesa 3D graphics library's OpenGL implementation to perform hardware-accelerated rendering.
The graphical output during the ReactOS installation phase relies primarily on the VBE specification within the VESA standard.
The ReactOS project underwent an audit event related to leaked Windows source code in 2006, after which stricter code review processes were established.
ReactOS version 0.4.16 has been officially released, bringing a graphical installer, 3D hardware acceleration, and improved hardware support.

50%UnverifiedReactOS is a free and open-source operating system aimed at achieving binary compatibility with Windows NT.
50%UnverifiedReactOS strictly enforces clean-room reverse engineering principles, requiring that the engineers who analyze Windows behavior and the engineers who write the code must be different people.
50%UnverifiedReactOS is still not suitable for use as a daily primary system.
50%UnverifiedReactOS has long run primarily in virtual machines such as VirtualBox, VMware, and QEMU, and stability on real physical hardware has consistently been a pain point for the project.
50%UnverifiedReactOS is a free and open-source operating system aimed at achieving binary compatibility with Windows NT; it is not based on the Linux kernel but reimplements the Windows NT architecture from scratch.
50%UnverifiedReactOS primarily provides an OpenGL implementation via the open-source Mesa 3D graphics library and achieves hardware-accelerated rendering through open-source drivers adapted for specific graphics cards.
50%UnverifiedReactOS's pursuit of binary compatibility means that compiled .exe and .dll files can run directly on ReactOS without recompilation.
50%UnverifiedReactOS's binary compatibility goal is more ambitious than the Wine project, because it also needs to implement a complete NT kernel interface and a Windows-compatible driver model (WDM/KMDF).
50%UnverifiedThe ReactOS project has been under development for over twenty years since its founding in 1998 and remains in the Alpha stage to this day, with a version number of only 0.4.x.
50%UnverifiedReactOS's graphics subsystem corresponds to the Win32k subsystem in Windows and is responsible for window management, GDI drawing, and user input handling.
