Windows 11 Error Message Generator
Windows 11 redrew the classic dialog: rounded corners, a flat title bar with no gradient, a solid accent-blue default button and the Segoe UI Variable typeface. This generator reproduces that Fluent chrome exactly, so a screenshot reads as a current-build Windows box rather than a decade-old one.
Type your own title, message and buttons, pick an icon, and download the result as a PNG. Nothing is uploaded — the dialog is drawn on a canvas on your own device.

What people use it for
- Memes and joke screenshots that need to look like a current Windows build
- UI mockups and slide decks that need a placeholder dialog
- Bug-report illustrations where the real error can't be reproduced
Other Windows and Mac versions
