Today marks 30 years since the first commit to the ReactOS source tree. It's been such a long journey that many of our contributors today, including myself, were not alive during this event. Yet our mission to deliver "your favorite Windows apps and drivers in an open-source environment you can trust" continues to bring people together. Let's take a brief look at some of the high and low points throughout our history. ## Progress update: fixing the ReactOS test suite DevFeed: [Progress update: fixing the ReactOS test suite]() Original publisher: [Read original article]() Published: 2025-11-04T00:00:00Z Content type: opinion Language: en Sources: [Front Page on ReactOS Website]() Topics: [Testing](), [WINE](), [Windows](), [gcc](), [MSVC](), [x86]() Tags: [changes](), [developer](), [free](), [gcc](), [msvc](), [open-source](), [os](), [react](), [reactos](), [tests](), [update](), [win32](), [winapi](), [windows](), [wine](), [x86]() ### AI overview A ReactOS project developer describes work to clean up the neglected test suite. The update reports fixes to 55 existing test modules, five new modules, broader testing across Windows versions and compiler toolchains, and changes intended to improve synchronization with Wine 10.0. The supplied text also states that the full test suite can now run on Windows Vista without a bugcheck. ### Source excerpt For many years, the ReactOS test suite was neglected. It was a random collection of our own tests and old Wine tests that were only checked against Windows Server 2003 and sometimes a random newer version of Windows up to the discretion of the contributor. The Wine tests we imported were heavily modified and the changes made weren't always well documented. I'm here to clean up this mess. I have been deeply involved with the ReactOS project since 2023 and in May of 2024 I became an official project developer. ## An initial investigation into WDDM on ReactOS DevFeed: [An initial investigation into WDDM on ReactOS]() Original publisher: [Read original article]() Published: 2025-10-07T00:00:00Z Content type: article Language: en Sources: [Front Page on ReactOS Website]() Topics: [ReactOS](), [Windows](), [GPU](), [Hardware](), [DirectX](), [OpenGL](), [Graphics]() Tags: [directx](), [free](), [gpu](), [graphics](), [hardware](), [open-source](), [opengl](), [os](), [react](), [reactos](), [win32](), [winapi]() ### AI overview This article investigates the Windows Display Driver Model (WDDM) in ReactOS, describing how Vista-era changes shifted GPU management toward driver vendors and examining related display-driver behavior, OpenGL ICD loading, and Vulkan similarities. ### Source excerpt The history of ReactOS spans a wider range than the lives of many of the people who work on it today. Incredible individuals have come and gone from the project with vastly different goals for what they want to see developed. In recent years, better hardware support has emerged as one of those goals. As ReactOS gazes towards the world of Vista and beyond, a few questions about how hardware works emerge. ## Carl Bialorucki hired to improve ReactOS test suite DevFeed: [Carl Bialorucki hired to improve ReactOS test suite]() Original publisher: [Read original article]() Published: 2025-07-04T00:00:00Z Content type: release Language: en Sources: [Front Page on ReactOS Website]() Topics: [Testing](), [Development](), [Windows](), [Kernel](), [WINE](), [x86]() Tags: [2025](), [automated](), [crashes](), [development](), [free](), [open-source](), [os](), [project](), [pull-requests](), [react](), [reactos](), [testing](), [win32](), [winapi](), [windows](), [wine](), [x86](), [x86-64]() ### AI overview Carl Bialorucki announces a full-time contract with ReactOS Deutschland e.V. to improve ReactOS's test infrastructure.
