Windows Error Message Generator
Build a custom Windows-style error popup with your own title, message, icon and buttons — then download it as a PNG.
Nothing is uploaded. The popup is drawn on your device — it's cosmetic only.
Pick your Windows version
The generator above draws the Windows 10 dialog. Every Windows release styled its error boxes differently — XP’s Luna blue title bar, Windows 7’s Aero glass, Windows 11’s rounded Fluent chrome — so each one has its own generator that draws it properly.

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