I use this script for Windows 11 experiments (same as

Problem is that this is very slow (easily factor >= 20), the Windows
setup crashes trying to configure the keyboard and network.
Technically I can get a cmd.exe shell with Shift-F10, but that doesn't
help a lot without network access.
Basically this is the reason why ms-nfs41-client has no Release
binaries for ARM64 - the sources build for ARM64, but there is no way
for me to test them... ;-(
