A silly new app has been doing the rounds this week: Windows 95 as a standalone application. Running on Windows, macOS, and Linux, the Windows 95 "app" combines Electron (a framework for building desktop applications using JavaScript and other Web technology) with an existing x86 emulator written in JavaScript. The emulator can run a bunch of operating systems: for the app, it's preloaded with Windows 95.

This is, of course, software piracy. The developer of the app has no rights to distribute Windows 95 like this, and I'm a little surprised that the app hasn't been yanked from GitHub yet. And for now, the app is just a toy; there's no real reason to run Windows 95 like this, other than the novelty factor of it actually working.
