QEMU’s qcow2 format offers the most flexible, snapshot-friendly, and accurate replication of the Windows 98 environment available in 2025. It transforms your $3,000 ultrabook into a time machine back to 1998.
Introduction: Why Windows 98 in 2025? In an era of NVMe SSDs, 16-core CPUs, and ray-traced graphics, the clatter of a dial-up modem and the chime of a 32-bit operating system seem like ancient history. Yet, for retro gamers, industrial control system administrators, and software archivists, Windows 98 remains a critical platform. It represents the pivot point between DOS command-line grit and the modern Windows NT architecture.

We need to emulate a mid-90s PC: Pentium (no SSE), 256MB RAM (Windows 98 crashes with >512MB), and an Intel 440BX chipset.
