Download Win11 in React – Windows 11 Desktop Simulation in Your Browser

Win11 in React is an open-source project that recreates the Windows 11 desktop experience entirely inside a web browser using React.js. It faithfully simulates the Windows 11 UI including the Start Menu, taskbar, desktop icons, File Explorer, settings panel, and several built-in apps — all running client-side with no server required.

This project is ideal for developers who want to explore React component design patterns, students learning frontend development, or anyone who simply wants to experience a polished Windows 11 interface without installing the operating system. The codebase is clean, well-organized, and makes excellent use of modern React hooks and CSS styling techniques.

You can run it directly in your browser by visiting the live demo, or clone the repository and host your own instance. It is a great showcase of how far modern web technologies have come in replicating complex native UI experiences.
