Microsoft does not officially distribute Windows 8.1 in QCOW2 format. QCOW2 is a disk image format used by QEMU/KVM, primarily in Linux virtualization environments. Downloading pre-made Windows QCOW2 images from unofficial sources often violates Microsoft’s licensing terms and carries security risks (malware, lack of updates). Legitimate use requires a genuine Windows license and manual installation from an ISO.
