For instance it can boot 64-Bit Linux system using the "Freeloader" utility. Furthermore, ReactOS now natively supports more file systems than all Windows versions combined. It runs LibreOffice, Firefox, Opera and more quite happily, and can even manage some earlier versions of popular commercial applications like Adobe Photoshop. The latest version (0.4.14 can also emulate the Japanese series of NEC PC-9800 computers). Incorporating parts of noted Windows emulator Wine. So it's clearly a bit behind the times, but ReactOS does have its uses. It's currently aiming at full compatibility with Windows Server 2003. Your mileage may vary – it's certainly not going to play nice with high-end games or software, and ReactOS isn't quite up to the Windows 11 level yet. It's completely open source, uses no proprietary Windows code, yet ReactOS is designed to be (and in some cases actually is) compatible with Windows drivers and applications. ReactOS does the same for the Windows NT architecture upon which all modern Windows versions are based. Linux, as you may know, is a ground-up reinterpretation of UNIX. It's worth playing with just for the cleanness of its desktop, and there are working web browsers and media players, although it's still rather experimental and many of the features of BeOS haven't quite been fully realized as yet. The second Beta release (R1) came out in December 2022 around 18 months after the previous beta. Technically Haiku is still considered to be under development so there's no stable release. The spirit of the closed source BeOS lives on in the form of Haiku, an open source re-implementation which began development immediately after Be's demise, and it has been in development since.īuilt from the ground up but designed to be backward-compatible with its classic quarry, Haiku follows BeOS' lead in its entirely modular design, allowing different components of the OS to be developed concurrently. A stylish multitasking OS that introduced a whole host of features that Windows, Linux and macOS would later adopt for their own, BeOS was a true multimedia innovator that left the market with a whimper when its rights were sold to Palm in 2001. We're a bit sad that BeOS didn't take off. The personal edition includes 6-months support and maintenance, while the commercial edition includes one-year of priority support and maintenance. There are two editions available: Personal, which retails for $129 per license, and Commercial, which retails at $229 per license, though volume discounts are available. Though its native file system is JFS, it ships with drivers for the FAT32 file system. It can also run most DOS programs including games. This means it can run 16 and 32-Bit OS/2 applications as well as certain 32-Bit Windows apps. The English edition will be released first with the Spanish, German and other language editions to follow.ĪrcaOS includes a robust Unix compatibility subsystem, featuring a variety of ported Linux apps and some drivers, but still features the OS/2 Workplace Shell.ĪrcaOS is a 32-Bit OS that runs on the x86 processor architecture, so should be compatible with some particularly old PCs. ArcaOS 5.1 is still being actively developed. While OS/2 barely survives as a legacy system, even after being extended for a while as eComStation. So ReactOS also needs to intercept these, process them, and reply, all while the app is none the wiser.ArcaOS is an operating system based on the last IBM release for OS/2. In addition, these software components will normally make system calls directly to the kernel on behalf of user-facing programs. The job before the ReactOS project is to provide a set of libraries, services, and (system) applications that are compatible with the ones Microsoft has. For example, explorer.exe is a program that not only browses files (user-facing), but also provides the desktop, Taskbar, and Start Menu. This includes not only user-facing apps like Word or Chrome, but also system applications. Applications that use these components.The Print Spooler is an example of this, as it waits for other programs to send something to the printer and manages that exchange. Basic software libraries that provide common functions like writing a file to disk.A kernel, which translates between software and hardware.At a very high level, an operating system is made up of the following components:
