Fake Update & Error Screens

These are cosmetic replicas rendered in your browser. They do not touch your operating system, install anything, or change any setting — closing the tab ends the effect. Do not use them to deceive someone into paying money or handing over access.

Use these responsibly

These are cosmetic replicas rendered in a browser tab. They install nothing, change no setting, and end when the tab closes. They are fine for a harmless desk prank, a film or stage prop, a UI mock-up or a screenshot. They are not fine for pressuring somebody into paying for a "fix", for locking a machine you do not own, or for anything that could be read as fraud.

Making one look convincing

  • Go fullscreen first — visible browser chrome gives it away instantly.
  • Match the screen to the actual operating system on the machine.
  • Set a duration long enough to be believable but short enough to end on its own.
  • Esc always exits.
