If you only need a short‑lived test environment, Microsoft’s official Windows 10 Enterprise Evaluation VMs (VHDX format) are fully legal for 90 days. Converting those VHDX files to QCOW2 is also permissible for evaluation purposes.
This guide explains how to safely acquire, convert, and deploy Windows 10 .qcow2 images on your virtualization infrastructure. What is a .qcow2 File?
VirtualBox does natively support QCOW2. However, you can convert the image to VDI or VMDK using qemu-img convert , then import it into VirtualBox. Alternatively, you can use the VBoxManage tool to convert VDI files, but the QCOW2 format itself is not directly usable. Windows 10.qcow2 Download
Always set the disk bus interface to VirtIO rather than IDE or SATA.
