ReactOS Celebrates 30 Years In Striving To Be An Open-Source Windows Implementation

Written by Michael Larabel in Operating Systems on 22 January 2026 at 05:57 AM EST. 58 Comments
The ReactOS project is celebrating today that it marks 30 years since their first code commit in the ReactOS source tree. During the past 30 years now the project has seen more than 88k commits from more than 300 developers as it seeks to be a robust open-source Windows implementation. In their 30 year birthday blog post they also provide a look ahead at what they're working on.

ReactOS in their blog post today provided a look back at how far the project has come as well as some screenshots from their earlier days:

The future of ReactOS is arguably what is most interesting. Among the items they are working on moving forward is their new "RosBE" build environment for developers, a new NTFS file-system driver, a new ATA storage driver, SMP multi-processor support, class 3 UEFI systems, address space layout randomization for kernel and user-space, and modern GPU drivers built on Microsoft's WDDM model. They still got a lot of work to go in really being a usable platform but at least they are advancing at a more brisk pace than GNU Hurd.

More details for those interested via the ReactOS.org blog post.
