An operating system designed to run legacy software and drivers, continuing support for older x86 PCs and legacy applications not compatible with modern Windows versions
ArcaOS is an operating system based on an open source branch of IBM's OS/2. It is designed to run older applications and device drivers that are incompatible or unstable on modern versions of Windows.
One of the key goals of ArcaOS is maintaining support for legacy software that relies on 16-bit installers, DirectX 5 graphics, and older multimedia frameworks. Many business applications from the 1990s and early 2000s fall into this category.
In contrast to Windows 10's frequent updates and interface changes, ArcaOS provides a consistent environment optimized for productivity and compatibility. It includes updated drivers for modern hardware like SSDs and USB 3.0 devices while retaining OS/2's classic Workplace Shell GUI.
Key features include compatibility with older office suites like WordPerfect and Lotus SmartSuite, native DOS and Windows 3.x session support, integrated multimedia and internet capabilities, and a bundle of open source software adapted for OS/2. The operating system is optimized to run well even on older Pentium hardware.
ArcaOS aims to be a dependable platform for running essential legacy software that has become unusable or unreliable on modern systems. It brings new life to aging PCs while providing a familiar desktop experience focused on stability and compatibility.
