PCjs uses JavaScript to emulate x86 hardware architecture. This allows the Windows XP operating system to believe it is running on real, physical hardware. It simulates the CPU, RAM, and storage necessary for the OS to boot. 1. Performance (The "Slow" Reality)

Below is a working (though slow) configuration for Windows XP on PCjs. Save this as winxp.json or machine.xml depending on your PCjs version.
Google Chrome, Mozilla Firefox, or Microsoft Edge are highly recommended. Ensure your browser is updated to the latest version to take advantage of the newest WebAssembly compilation optimizations.
: Unlike many modern emulators that use WebAssembly (Wasm) for speed, PCjs is written entirely in JavaScript. This allows it to run on virtually any modern browser without external plugins. Component-Based Simulation You can bridge this to your host OS's
to keep internal system clocks accurately synchronized.
Windows XP has a legendary reputation for its stability and iconic "Luna" design, but running it today can be tricky. While the project specializes in high-fidelity browser-based emulations of classic 1970s and 80s hardware, its support for newer systems like Windows XP is limited compared to its robust older libraries.
