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.

Hi, my name is Carl J. Bialorucki. I started making a name for myself in the ReactOS community by contributing several shell improvements. In May of 2024 I was added to the core development team and in March of 2025 I led the release of ReactOS 0.4.15 after the previous release manager was unable to continue working on the project.

I’m pleased to announce that I was hired for a full-time contract position with ReactOS Deutschland e.V. in May of 2025.

Greetings from the ReactOS Team! This year, we will start with a short summary highlighting ongoing work on the project as well as announcing the selection of our brand new developers. We will also talk about the current situation with symmetric multiprocessing (SMP) support in ReactOS. Development team enlargement Over the last decade, the number of people in the project team base has not changed much. While development continued and still continues as usual, the development team hadn’t seen any increase in new developers.

Greetings! Welcome to the third blog of the series “1st-stage GUI setup”: September 2023: Partly Wine-syncing setupapi October-November 2023: Making partitioning UI work December 2023: First tests In this third blog post, I will cover my work done during the month of December 2023: testing the whole 1st-stage GUI setup, together with the partially wine-synced setupapi dll. Finishing and testing the partitioning page UI The first week was devoted to finally putting together the code for manipulating partitions from the user interface, using the new workflow, and testing it.

Greetings! Welcome to the second blog of the series “1st-stage GUI setup”: 1. September 2023: partly Wine-syncing setupapi 2. October-November 2023: Making partitioning UI work 3. December 2023: First tests As you may have noticed, I have been quite silent about my work and not regularly writing blog posts about what I have done so far. Well, I am more concerned about getting actual code written and working before discussing about it, instead of doing that about half-done not-yet-tested code; much like what the GUI setup was during these previous months.

Greetings to all ReactOS followers! As many of you certainly are aware by now, I have been officially hired by ReactOS Deutschland e.V. to develop the graphical version of the 1st-stage ReactOS installer (“1st-stage GUI setup”). During this first month (September 2023), my goal was to partly sync the code of the setupapi.dll module with Wine’s. Indeed, this module was forked way back in 2005, with later partial synchronizations of its code for some of its functions.

Salutations from the ReactOS project team! In previous posts, we talked about the ReactOS releasing process and the development status of the project, as well as the hiring of our long-term developer Hermès Bélusca-Maïto (HBelusca). We are making an effort to publish at least 3 newsletters per year, depending on how the development workflow goes. In this newsletter we will highlight some of the contributions made by project developers and contributors, as well as future plans and headlines.

Our team proudly announces that ReactOS Deutschland e.V. has hired Hermès Bélusca-Maïto to work full-time on the ReactOS GUI Setup for the next 5 months, starting September 2, 2023. Hermès is a long-time contributor and developer who worked on the project since 2012. He has several skills and expertise into various components of ReactOS, notably being the Client/Server Runtime Subsystem (CSRSS), Console Server Subsystem (CONSRV), NTVDM, and others. His upcoming goal is to finish the first-stage ReactOS GUI setup, which offers an alternative to the classic first-stage text-mode setup (also called USETUP).

Hello ReactOS followers and enthusiasts! It has been quite a long time since we published the 101th newsletter and so far no further updates have been posted since then. While the ReactOS Twitter account does provide announcements, posts about working applications and such from time to time, much of what is happening with the project as a whole isn’t mentioned. Most of what we are going to talk about is the current situation with releases and overall ReactOS development.

We are proud to announce that ReactOS has been accepted into the 2022 Google Summer of Code program. The GSOC program is a great opportunity for a fresh contributors looking to join the Open Source and Free Software movement. This year we are looking for new contributors who want to enhance skills in kernel development and NT architecture. Our team consists of skilled mentors who are going to guide eager students with ReactOS architecture and development practices.
