Browser simulation
The reveal timer pauses while you read these sources.
Microsoft documents both blue and black stop screens. The newer design applies to updated Windows 11 24H2 and later; this page does not infer patch levels. The QR code is omitted, the wording simplified, and progress and stop codes simulated.
The system is inferred from browser platform information and may be wrong. Windows patch versions are not inferred. The default language follows browser preferences, which can differ from the system language.
Every screen is drawn by this webpage. Progress, error codes and stack traces are fictional. The prank reveals itself after 8 seconds. Press Esc to end it at any time.
