Quick Start Guide

New to Windows 98 Web Edition? Here's how to get started:

  1. Launch the Demo: Click the live demo link above.
  2. Open the Start Menu: Click the Start button in the bottom-left corner.
  3. Try Some Apps: Navigate to Programs → Accessories → Games → Solitaire or Programs → Accessories → WordPad.
  4. Explore Your Folders: Double-click My Computer from Desktop and go to File → Insert Removable Disk on top left corner of the window to mount a folder from your real computer as a virtual drive. You can open and edit text files, play music & video files and also play your SWF Flash games.
  5. Browse the Retro Web: Double-click Internet Explorer from Desktop and navigate to your favorite websites in 1998. Try google.com!
  6. Customize Your Desktop: Right-click anywhere on the desktop → Properties to change color schemes and wallpapers. You can also go to click Start button and navigate to Settings → Control Panel → Desktop Themes to apply a new theme.
  7. Meet Clippy: Launch the Assistant from the Start Menu (under Programs → Accessories) to activate the AI-powered Clippy. Ask about anything you want! Once running, you can find it in the system tray.

Pro Tips:

  • Drag windows by their title bars to move them around.
  • Store your files in the My Documents folder for easy access.
  • Right-click almost anywhere for context menus.
  • Install as a PWA (look for the install icon in your browser's address bar) for a more app-like experience.
  • Mount Local Folders: Open My Computer, go to File → Insert Removable Disk to mount a folder from your real computer as a virtual drive.

Background

This project started as a small experiment to give my portfolio website a Windows 98 theme. As I explored many WebOS UI and filesystem libraries and dabbled with LLM agents like Google Jules, that experiment gradually grew into a full browser‑based desktop environment.

Over time, it became a challenge: to push how far a vanilla JavaScript application (no React, Vue, or Angular) could go, to explore OS‑like UI structures in the browser, and to test my ability to design and sustain a larger, long‑running personal project. It's also my opportunity to experience collaboration with LLM AI and test their limits.

Why Windows 98? The main inspiration for this is actually my (parents') first computer ever, a Windows 98 machine. It is my first experience with a computer, and I remember the excitement of tinkering with it. That feeling is what I'd like for you to experience as well.

What You Can Do Here

  • Explore a browser-based desktop that behaves like a classic operating system.
  • Change themes, colors, wallpapers, and sound schemes to customize your experience.
  • Run classic games and utilities in an authentic retro environment.
  • Create, edit, and manage files in a persistent virtual file system.
  • Mount local folders and .ISO files as virtual drives (A:, D:, etc.) to work with your real files.
  • Install the project as a Progressive Web App for offline access.
  • Chat with an AI-powered assistant for help and nostalgia.

🐞 Bug Reporting

We want to make Windows 98 Web Edition as stable and authentic as possible! If you encounter any issues, please let us know.

The Preferred Way: GitHub Issues

For the best tracking, please report bugs directly on our GitHub repository. This allows the community to discuss, track, and fix issues transparently.

👉 Report a Bug on GitHub

In-App Reporting

If you don't have a GitHub account, you can also use the Report a Bug application within the OS (Start → Programs → Accessories → Report a Bug). Note that these reports are anonymous and we may not be able to follow up with you directly.

Special Features

  • Assistant (Clippy): An intelligent assistant that can answer questions and help navigate the system.

A complete and up-to-date list of applications, including development notes and how to create your own apps, is available here:

📄 Application Development Guide

For Developers and Tinkerers

This project is designed to be forked, studied, and experimented with. The codebase is structured to be modular and extensible.

Key Features for Developers:

  • Applications are registered dynamically through a central configuration system.
  • Apps can be window-based (traditional GUI apps) or function-based.
  • Context menus, menu bars, and keyboard shortcuts are easily configurable.
  • Themes and visual styles are data-driven.
  • Virtual file system with persistent storage (IndexedDB) allows for real file operations.
  • Event-driven architecture with a global window.System API.

Creating Your First App:

import { Application } from '../../system/application.js';

export class HelloWorldApp extends Application {
  static config = {
    id: 'hello-world',
    title: 'Hello World',
    width: 400,
    height: 300
  };

  _createWindow() {
    const win = new window.$Window({
      title: this.title,
      width: this.width,
      height: this.height,
    });
    win.$content.append('<div style="padding: 20px;">Hello from Windows 98!</div>');
    return win;
  }
}

For detailed instructions, see the Application Development Guide.

Architecture Overview

Core Components

  • System Core (src/system/): Handles the fundamental "OS" logic.

    • os-init.js: Boot process and system initialization.
    • window-manager.js: Window lifecycle and z-index management.
    • app-manager.js: Application registration and launching.
    • zenfs-init.js: Virtual file system configuration.

  • Shell (src/shell/): Desktop environment components (Taskbar, Start Menu, Desktop, Explorer).

  • Applications (src/apps/): Individual applications decoupled from the core system.

  • Global API:

    • window.System.launchApp(appId, data): Launch applications programmatically.
    • window.fs: Access the virtual file system (ZenFS).
    • window.mounts: View currently mounted file systems.

Virtual File System

Uses ZenFS to provide a Unix-like file system in the browser:

  • Root (/): InMemory file system, containing mount points for other drives.
  • C: Drive (/C:): Persistent storage (IndexedDB). Data survives browser restarts.
  • A:, D:, E:, etc.: Can be used to mount local folders (via File System Access API) or ISO images.

AI Assistant

Clippy is reintroduced as an optional, AI-powered assistant that provides contextual help and guidance.

How It Works:

  • Launch the Assistant app from the Start Menu or Desktop.
  • Type your question or request in natural language.
  • Clippy processes your input using a language model backend.

Privacy Note: Conversations with Clippy are sent to a backend API for processing. The backend service lives here: 👉 resume-chat-api

Future Roadmap

  • Theme Installation: Allow users to install custom themes (.theme/.themepack/.reg).
  • More Screensavers: Recreate more Windows 98 Plus! screensavers.
