About this tool
This fake error message generator recreates the classic Windows-style dialog box, but with text you control. Set the window title, the message, the icon (error, warning or information) and which buttons appear, then use the result for a meme, a joke screenshot or a lighthearted desktop prank.
It's purely cosmetic — nothing is actually wrong and nothing is uploaded. For more pranks, see the fake blue screen and hacker typer.
