❌ – PCjs shines for DOS and Win95. XP pushes the emulator past its sweet spot. ❌ No 3D acceleration – Forget DirectX games or Aero themes. ❌ Disk I/O is molasses – Installing software inside XP takes ages. ❌ No USB support – XP’s USB stack is emulated poorly or not at all. ❌ Modern web limitations – Browsers throttle background tabs; PCjs needs to be foreground.
The emulator may run slower than a dedicated native virtual machine.

Windows XP, released in 2001, was a landmark because it unified the consumer (9x) and business (NT) lines under the stable Windows NT kernel. For emulators like PCjs, XP represents a significant jump in complexity compared to Windows 1.0 or 3.1.
By default, changes made to a PCjs virtual machine are temporary. Since browsers operate on a stateless or strictly sandboxed storage model (like IndexedDB), saving large files or installing massive software suites requires exporting modified disk images back to the host machine's local storage. How to Get the Most Out of PCjs Windows XP ❌ – PCjs shines for DOS and Win95
Usually configured between 128MB and 256MB of RAM—enough to boot XP smoothly without overwhelming the host browser's memory allocation.
PCjs is an open-source project dedicated to creating fast, full-featured computer simulations written entirely in JavaScript. By leveraging modern browser capabilities, it enables users to run classic operating systems like DOS, Windows 95, OS/2, and 1.2.1 , 1.2.4 . ❌ Disk I/O is molasses – Installing software
There is a bittersweet quality to running Windows XP in PCjs.
Incredible technical achievement in browser-based JavaScript.
If you approach it as a technical demo of how far browser-based emulation has come, you’ll be delighted. If you expect to use Outlook 2003 or play Pinball, you’ll be frustrated.
