GuofangandClaude Sonnet 5.5 65a5780e02 Install OpenSSH Server during Windows setup
Install it at first logon from the Win32-OpenSSH zip on the seed ISO via
Configure-Windows.ps1 -InstallOpenSSH, replacing the manual 05/06 batch
files. The administrator public key now comes from the host
(SSH_PUBLIC_KEY_FILE or ~/.ssh/id_*.pub) instead of being hardcoded.
