Run Windows XP Directly in Your Browser with win32.run

Overview

win32.run is a web‑based emulator that reproduces the Windows XP desktop environment in the browser. Accessing https://win32.run/ and pressing Enter loads the XP interface (Bliss wallpaper, taskbar, Start menu, Explorer with C: and D: drives) without installing any software.

Key Features

Accurate recreation of the XP desktop, including the classic wallpaper, taskbar, Start menu and file explorer with C: and D: drives.

Built‑in classic games such as Minesweeper, Solitaire, as well as additional titles like Minecraft and space shooters.

Support for legacy XP applications: Microsoft Word 98, ZIP compression, Flash (.swf) playback, and subtitle‑enabled video playback.

Hidden utilities: install third‑party mini‑apps, drag‑and‑drop files into the virtual explorer, and play .mp4/.srt video pairs.

Internet Explorer runs inside the emulated environment, allowing browsing of modern sites.

Technical Implementation

The project is built with Svelte/SvelteKit and styled using Tailwind CSS. It runs entirely client‑side: all files are processed locally in the browser’s IndexedDB, and no server‑side uploads occur. A standard Node.js environment with npm is required only for building and serving the site.

Local Development

git clone https://github.com/ducbao414/win32.run.git
cd win32.run-main
npm install
npm run dev   # development server at http://localhost:3000

To create a production build:

npm run build   # outputs to win32.run-main/build
npm run preview

Deployment

A typical deployment uses Ubuntu with NGINX (or any static‑file server). After uploading the build folder together with package.json and package-lock.json, install dependencies and start the server, for example:

npm install
pm2 start build/index.js   # serves on port 3000

Limitations & Considerations

Hardware compatibility issues of a real XP installation (drivers, UEFI, partitioning) are bypassed because the emulation runs purely in the browser.

Performance depends on the client’s CPU, RAM and JavaScript engine.

The project targets SvelteKit; future breaking changes in SvelteKit would require a major refactor.
