For the phony Windows guest we used the registry information from a 32 bit Windows 7 instance. This version of Windows is EOL. Newer Windows changed the versioning scheme so we now use the build ID to distinguish between versions, but we have not tested this in virt-v2v upstream before. I grabbed HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion from a real 64 bit Windows 2022 Server instance, minus identifying strings. Various tests had to be updated because they contained references to Windows 7, or because virtio-win contains more drivers for Windows 2022.
