Microsoft's Windows XP, launched in 2001, has a lifespan of over 17 years and has inspired a developer to create a web-based simulation called Win32.run. This project recreates a fictional instance of Windows XP using web technologies, allowing users to explore a simulated file system and interact with embedded programs. The developer originally created the simulation as a tribute to the operating system from his childhood, using the Svelte framework, SvelteKit, and Tailwind CSS. However, the project was halted due to significant breaking changes in SvelteKit that made the codebase difficult for other developers to understand. The simulation operates on a client-side architecture, enabling users to run it locally in their browsers. There are also ongoing efforts to transform various editions of Windows into web applications, with projects ranging from simple browser-based simulations to more complex emulation tools. For a more immersive experience, users can run legacy operating systems like Windows XP in dedicated virtual machines using modern desktop hypervisors such as VMware Workstation.
