Windows 8 remains a popular choice for legacy software testing and lightweight virtualization. Using a QCOW2 (QEMU Copy-On-Write) disk image is the most efficient way to run this OS in modern virtualized environments like KVM, QEMU, or Proxmox. Why Use QCOW2 for Windows 8?
The file only occupies physical disk space as data is written.
