100% Safe & Free

Runs entirely in your browser, no installation, no permissions, no data collected

This is a free, browser-based prank tool that displays a convincing fake Windows update screen on any computer. The tool covers 8 different operating system styles - Windows 11, Windows 10, Windows 7, Windows XP, the Blue Screen of Death (BSOD), macOS, a Linux apt-update terminal, and iOS - so you can match the prank to whatever computer your target is using.

Everything runs locally in the browser. Nothing is downloaded, installed, or sent anywhere. Press Esc at any time to exit, even after going fullscreen with F11. The prank works on Windows, Mac, Linux, ChromeOS, iPhone, iPad, and Android - any device with a modern web browser.

Beyond the basic update simulation, advanced features include custom status messages, a stuck-at-percentage mode (the most realistic touch - real Windows updates do hang at 27% for hours), a scheduled-start countdown, random critical error popups mid-update, synthesized sound effects (HDD grinding loop, error beeps, startup chimes), and a "Just Kidding" reveal at the end so the joke ends well.

1. Pick a screen type - Choose between Windows 11, Windows 10, Windows 7, Windows XP, BSOD, macOS, Linux terminal, or iOS depending on what computer you're pranking.

2. Pick a preset (or skip it) - Use a quick preset for common scenarios like a 5-minute office prank or the classic 27% freeze, or skip and configure manually.

3. Set duration and starting percentage - 5-10 minutes works for most office pranks. Start at 0% for a fresh update or 80%+ for an "almost done" effect.

4. Customize text (optional) - Write your own title and subtitle, or set a custom BSOD stop code. Leave blank to use realistic defaults.

5. Toggle prank options - Enable sound effects, random error popups, the "Just Kidding" reveal screen, and the hold-ESC-to-exit safety.

6. Schedule the start delay - Set a 10-30 second delay so you can step away before the prank kicks in.

7. Go fullscreen and start - Click Enter Fullscreen, then Start Prank. Press Esc when the joke is over.

Yes. The tool only displays a fake screen inside your browser. It does not modify, install, download, or change any files or system settings. Press Esc at any time to exit.

Press the Esc key once. On mobile devices, tap the screen to reveal the exit hint. If you used real fullscreen with F11, Esc exits fullscreen too. If you enabled "Hold ESC to Exit", hold the key for one second.

No. Nothing is installed and no system changes happen. The tool runs entirely inside the web browser tab and exits cleanly when you press Esc.

Yes. The tool runs on iOS Safari, Android Chrome, and any modern mobile browser. Tap the screen during the prank to reveal the exit hint.

Yes. Use the Custom Text fields to write your own title and subtitle. For BSOD mode, set any stop code you want - leave it blank to use the default CRITICAL_PROCESS_DIED.

Stuck Mode freezes the progress at a percentage you choose. Real Windows updates often hang at the same number for hours, so this produces the most believable prank. Try 27% for the classic.

After the page loads once, the tool runs entirely in the browser without needing a connection. No data is sent anywhere.

No. All sound effects are generated on-the-fly using the Web Audio API - they're synthesized tones, not real Microsoft or Apple sounds.

Yes. Click the Share Link button to copy a URL containing all your current settings. Anyone who opens the link sees the same configuration ready to start.

Modern browsers require a user gesture before audio can play. Sound starts working after you click Start Prank - that counts as the gesture.
