This is a free, browser-based fake computer freeze prank tool that displays a convincing frozen desktop screen. Five freeze modes are included, each producing a different "broken computer" effect that anyone unfamiliar with the prank will believe is real.

Cursor Trail mode leaves a frozen copy of the mouse cursor everywhere the user moves their mouse - within seconds the screen fills with arrows. Screenshot mode captures a fake desktop image and locks it in place. Click Trail drops a red marker on every click. Glitch shows random screen tearing and color noise. Ghost Cursor lets the cursor move normally but everything else stays frozen.

You can layer in fake error popups and a synthesized system beep on every click for extra chaos. Press Esc at any time to exit - nothing is actually frozen, the computer continues running normally underneath the overlay.

1. Pick a freeze mode - Cursor Trail is the best starting point because it's instantly recognizable and dramatic. Try Glitch for a "system corrupted" vibe.

2. Configure popups - Optional fake Windows error popups can layer on top of the freeze. Set the frequency or trigger them only on click.

3. Toggle sound and cursor options - Enable system beep on click for the classic "computer is mad" effect. Hide the real cursor for full immersion.

4. Schedule the start delay - Set 10-30 seconds so you can leave the room before the freeze kicks in.

5. Go fullscreen and click Freeze - Click Enter Fullscreen, then Freeze Screen. Walk away. Press Esc when the joke is over.

No. The tool only displays a fake frozen screen inside your browser tab. The computer continues to run normally underneath - you can press Esc at any time to exit and return to your desktop.

Cursor Trail leaves frozen cursor copies wherever the user moves their mouse. Screenshot Freeze captures the current screen and locks it in place. Click Trail places frozen click markers wherever they click. Glitch shows random screen tearing. Ghost Cursor shows the real cursor moving but everything else is frozen.

Every time the user moves the mouse, a copy of the cursor stays on screen at that position - making it look like the cursor is multiplying instead of moving. After a few seconds, the screen fills with frozen cursors.

The beeps are synthesized in your browser using the Web Audio API - they sound like a computer that has stopped responding to input. No audio files are downloaded or played from your system.

Press the Esc key once. If "Hold ESC to Exit" is enabled, hold ESC for one second. On mobile, tap the screen to reveal the exit hint. The exit is always available - the computer is never actually locked.

Yes. Set a delay of 5 to 60 seconds before the freeze starts, giving you time to step away from the computer before the prank begins.

Yes. The freeze runs on iOS Safari, Android Chrome, and any modern mobile browser. Touch events are tracked the same way mouse movements are. Tap during the prank to see the exit hint.

No. Nothing is installed and no settings are changed. Once you press Esc and close the browser tab, everything returns to normal immediately.

Pair with the Fake Windows Update for an "and now it's stuck" follow-up, or with the Fake Virus Scanner to imply the freeze is virus-related.
