TinyRetroPad, a 2.5 KB 'Notepad' for Windows

A former Microsoft engineer created TinyRetroPad, a minimalist text editor for Windows that takes up only 2.5 KB of disk space, as a nostalgic recreation of the original Notepad from the early 1990s.

Background

- A former Microsoft engineer created TinyRetroPad, a text editor for Windows that is only 2.5 KB in size — far smaller than Notepad (which is around 200 KB) and absolutely tiny compared to apps like VS Code (hundreds of megabytes). - The project is a technical stunt: it was written entirely in raw x86 assembly language (no high-level languages like C or Rust), compiled into a single tiny executable that fits on a floppy disk thousands of times over. - It deliberately strips away almost every modern feature: no tabs, syntax highlighting, settings — just plain text editing with a retro aesthetic (green text on black, chunky fonts). - The significance lies in how software bloat has become normal. Modern apps often use giant frameworks (Electron, .NET) that bundle entire browsers or runtimes, whereas TinyRetroPad shows what is possible when a skilled developer works close to the metal. It is both a nostalgic homage to DOS-era tools and a pointed commentary on today's bloated software.
