Make a fake blue screen message

Create harmless browser HTML that resembles a retro Windows stop screen without crashing a computer.

The frame below runs the same code as this page, in the reader's own browser. Nothing is sent to us, and nothing is sent to you.

Pick a dark background and the text and panels follow it, so the frame stays readable on a dark page.

How it works

The heading, message, and displayed code are HTML-escaped before insertion into a full-height blue panel with white monospace text. This produces presentation markup only: it never invokes a kernel bug check, validates the code, or writes a crash dump.

  • The familiar colour and hexadecimal-looking example are visual choices rather than diagnostic evidence.
  • Escaping keeps angle brackets and quotes visible instead of executing them as markup.

Worked example

Make a fake blue screen message
Input
											Title: A problem has been detected
Message: Coffee not found
Stop code: 0xC0FFEE
Output
												<div style="min-height:100vh;background:#0000aa;color:white;padding:8vh;font:24px monospace"><h1>A problem has been detected</h1><p>Coffee not found</p><p>*** STOP: 0xC0FFEE</p></div>

When to use this

Presentation slides use fictional error visuals, video props display a full-screen browser panel, and web exercises recreate high-contrast monospace layouts.

Edge cases

  • A title containing <script> is shown as text because reserved HTML characters are escaped.
  • An invented value such as 0xC0FFEE remains unchanged and must not be read as a Microsoft diagnosis.
  • Opening the result cannot create the dump file that Windows may write after a genuine kernel stop.
