Boot Windows XP in your browser — no download, no install
This Windows XP simulator runs the full Luna desktop experience entirely inside your web browser. There is no virtual machine, no download, and no installer — just click Launch XP Simulator and the boot screen takes over the page. After the loading bar finishes, the classic XP startup chime plays and the Bliss desktop fades in with the green Start button, blue taskbar, and clickable desktop icons. Everything you remember from the early 2000s is here, recreated in HTML, CSS, and JavaScript so anyone with a browser can use it.
It is the perfect prank for office computers, an instant nostalgia hit for retro fans, a screen-share showpiece for streamers, and a usable simulation for anyone who needs to demonstrate the XP UI in a video, blog post, or design mockup.
What’s inside the Windows XP simulator
The desktop is fully interactive. Double-click any icon to launch a real working application, click Start for the classic two-column menu, and drag, resize, minimize, or maximize any window. The taskbar at the bottom shows every open program and updates in real time, just like the real Windows XP.
Working applications
- Notepad — full-featured text editor with the original menu bar (File, Edit, Format, View, Help) and a live title bar that updates as you type.
- Calculator — Standard mode with all four operations, square root, reciprocal, percent, sign toggle, and the classic clear / clear-entry / backspace buttons.
- Paint — drawing canvas with pencil, brush, eraser, line, rectangle, oval, paint-bucket fill, and eyedropper tools, plus the original 14-colour palette.
- Internet Explorer — multi-page browsing simulator with working back / forward / refresh / home buttons, an editable address bar, history navigation, and fake versions of MSN.com, Google, Yahoo!, Bing, and Hotmail. Click any blue link to navigate.
- My Computer — full Explorer view with the blue task pane sidebar, Files Stored on This Computer, Hard Disk Drives, and Devices with Removable Storage sections.
- My Documents — file-folder grid with the classic “File and Folder Tasks” sidebar.
- Recycle Bin — empty bin view with the standard task list.
- Minesweeper — fully playable 9×9 board with first-click safety, flood-fill reveal on zero cells, flag-on-right-click, mine counter, timer, and the classic smiley face that turns shocked when you lose and cool when you win.
- Solitaire (Klondike) — full deck shuffle, stock and waste piles, four foundations, seven tableau columns, automatic face-down flipping, and win detection. Click a card to select it, click a destination pile to move.
How the simulation works
Everything happens inside one webpage. The window manager is plain JavaScript — drag handlers, resize handles on every edge, a z-order stack so clicking a window brings it to the front, and a taskbar that mirrors the open-window list. The boot screen is an animated CSS gradient with a sliding progress bar. The startup chime is generated live with the Web Audio API, so no sound files need to be downloaded.
The XP wallpaper is a stack of CSS gradients tuned to approximate the famous Bliss photograph (the green hill and blue sky shot in California’s Sonoma County), the taskbar uses the original Luna blue gradient, and the Start button uses the Luna green gradient with the classic skewed four-color flag.
Nothing is uploaded or saved
The simulator is a static webpage. There are no cookies tracking your activity, no analytics recording what you type into Notepad, no calls home to any server, and no files written to your machine. Everything you do — drawings in Paint, text in Notepad, played games of Solitaire — exists only in your browser tab. Refreshing the page resets the entire desktop to a freshly booted state.
What people use the XP simulator for
- Office pranks. Open the simulator on a coworker’s screen during lunch and watch the confusion when they return to find their “operating system” has changed.
- Streaming and content creation. A clean, recognizable XP desktop is great background for retro-themed videos, throwback streams, and screen recordings without the work of spinning up an actual VM.
- Design references and mockups. Designers and writers needing screenshots of the classic XP UI for blog posts, books, or presentations can grab them straight from the simulator.
- Nostalgia. Sometimes you just want to hear that startup chime, click the green Start button, and play one round of Minesweeper or Solitaire the way it was in 2003.
- Education and demos. Computer-history classes, UI/UX lectures, and YouTube explainers about how desktop operating systems evolved can use the simulator as a live demo.
Tips for the most convincing experience
- Press F11 (or accept the fullscreen prompt) before launching. This hides the browser address bar so the desktop fills the entire screen.
- Use the Start menu. Open Start → All Programs-style apps from the main column to build the most layered, lived-in desktop.
- Right-click on the desktop background. The classic Arrange / Refresh / Properties context menu is there, just like the real thing.
- Press ESC to exit. One press closes the topmost window. Pressing ESC with no windows open exits the simulator and returns you to this page.
- Double-click a desktop icon to open it. Single-click only selects the icon, the same as real Windows.
