ReactOS brings its Windows NT tribute act to ARM64

ReactOS has successfully booted on ARM64 architecture, marking a significant milestone for the project aimed at recreating Windows NT. This experimental build has been demonstrated running on ARM64 via QEMU and on the Raspberry Pi 5. The ARM64 port is currently a proof of concept with limited functionality, and users need a UEFI ARM64 system with GICv2 or v3 enabled to run it. The ReactOS team has emphasized the experimental nature of this development, and the project is still focused on compatibility with Windows Server 2003. ReactOS is described as "an alpha-quality operating system," intended for users willing to experiment on less critical devices.

Miss Windows XP or 7? Then I have a free, open-source alternative for you

ReactOS has merged its Live and Boot ISOs into a single installation image, simplifying the installation process for users. This integration allows users to test the OS in a live environment and transition to installation without needing multiple discs or USB drives. The installation process still resembles older Windows versions with a text-based setup, but a full graphical installation interface is expected in the upcoming 0.4.16 build. Additionally, ReactOS is expanding its hardware compatibility with a new ATA storage driver, enabling it to boot on a wider range of storage devices. ReactOS is currently in its alpha stage of development and is not yet suitable for everyday use.

Doubtful Linux can ever meaningfully challenge Windows 11? This new distro may change your mind

Loss32 is a new Linux distribution concept developed by Japanese developer Hikari no Yume, designed to provide a Windows-like desktop experience on the Linux kernel. It was introduced at the 39th Chaos Communication Congress in Germany. Loss32 integrates the Windows desktop experience using WINE, allowing Windows applications to run natively on Linux. Unlike ReactOS, which aims to reimplement the Windows NT kernel, Loss32 leverages the established Linux kernel and WINE for better reliability. The initial proof-of-concept for Loss32 is expected to be released in January 2026, although the timeline for a finished product remains uncertain. The project aims to create a user-friendly experience without common Microsoft-related issues, while also allowing the use of native Linux applications. The development of Loss32 may positively impact the WINE project, enhancing its functionality for all users.

ReactOS Starts 2026 With Another “Major Step” Toward Windows NT6 Compatibility

The ReactOS project is celebrating its 30th anniversary and has made significant progress in compatibility with Windows NT 6.0. The team has synchronized their implementation of the Microsoft C Runtime library (MSVCRT) with Wine 10.0, resulting in a 30% reduction in API test failures and improved support for various applications. Approximately 7,574 out of 25,517 test failures have been addressed, leading to a 29.6% improvement in overall stability.

6 exciting and niche OS projects that are quietly growing as users leave Windows

More individuals are dissatisfied with Windows due to updates, telemetry, and restrictive design choices, especially with the end of life for Windows 10 approaching. This has led to a subtle migration towards niche operating systems. Zorin OS is a user-friendly Linux distribution designed for newcomers, featuring a familiar interface that mimics Windows and macOS, and is powered by Ubuntu for stability. It includes Zorin Connect for synchronizing notifications and emphasizes security and privacy. Haiku is a lightweight operating system that serves as a successor to BeOS, focusing on speed and simplicity, built entirely from scratch for a snappy user experience. SerenityOS is an independent project created from the ground up, featuring a nostalgic aesthetic and a complete desktop environment, with a focus on usability and craftsmanship. Ultramarine Linux is a Fedora-based distribution that simplifies open-source software for users, offering multimedia codecs and multiple desktop environments for a comprehensive experience. Vanilla OS introduces a modern approach to Linux with immutability, protecting core system files and allowing independent application management to enhance stability. ReactOS aims to recreate the Windows experience using open-source code, focusing on compatibility with Windows applications and drivers while fostering a community around its development.

As Windows 10 signs off, ReactOS devs are exploring a long-awaited feature in WDDM support — investigation could pave the way for newer GPU hardware compatibility

The ReactOS development team is working on integrating the Windows Display Driver Model (WDDM) into their operating system as Windows 10 approaches its end-of-life. A significant challenge has been the lack of video driver documentation for both the older XDDM and the newer WDDM, but the emergence of open-source GPU drivers has provided valuable insights. ReactOS is an open-source project designed to run Windows software and drivers, developed entirely from scratch without relying on Linux or Unix. It is currently in an experimental phase and may not be suitable for daily use, lacking many modern features found in contemporary operating systems. ReactOS is notable for being the only open-source OS that can natively run Windows applications without compatibility layers.

ReactOS Making Progress On Windows WDDM Driver Support

The ReactOS project is working on supporting the Windows Display Driver Model (WDDM), which is a modern graphics driver architecture introduced with Microsoft Windows Vista. This development signifies a shift from older XDDM drivers and aims to keep ReactOS relevant as new hardware emerges. Recent efforts have focused on enabling communication between ReactOS and WDDM drivers, with progress reported by developer TheDarkFire, who noted that BasicDisplay.sys was successfully loaded in ReactOS, allowing the system to utilize modern monitors at full resolutions and refresh rates. However, limitations were encountered due to hardware support rather than the implementation of Win32k.

Forced E-Waste PCs And The Case Of Windows 11’s Trusted Platform

The process of upgrading Windows operating systems was straightforward until Windows 11, which introduced a new requirement for a Trusted Platform Module (TPM), potentially rendering many capable PCs obsolete. The TPM is used for boot validation and storing biometric data, but it complicates data recovery and may lock out legitimate users. Users have found ways to bypass Windows 11's TPM and CPU restrictions, allowing installation on unsupported hardware. Microsoft’s enforcement of these requirements remains uncertain, raising concerns about system reliability and user access to updates. Many users are opting to stay on Windows 10 while advocating for continued support from developers.

ReactOS, an Open Source Take on Windows

ReactOS is an open-source operating system designed to be compatible with Windows, aiming to recreate the Windows experience while ensuring compatibility with existing software applications. The first stable release occurred in 2011, followed by a beta version in 2013 that improved support for 64-bit systems. By 2020, ReactOS reached a Technical Alpha milestone, indicating progress in stability and performance. The latest version resembles the outdated Windows XP interface, which may appeal to some users but lacks modern functionality. The ReactOS Application Manager allows users to install applications, but many popular software versions are outdated or incompatible. Users are advised to use the Application Manager for installations, as external downloads can lead to issues. ReactOS appeals to Windows users reluctant to switch to Linux or invest in new hardware, but it remains a work in progress with bugs and limited application support. The project invites contributions to enhance the user interface and application compatibility.
