VM e2e findings on the real-user desktop:
1. Lock/login screen + wallpaper NOT branded (OEM About WAS) — Windows resets the
offline-baked personalization (PersonalizationCSP / default-user wallpaper / FVE)
during OOBE, same class as the UAC reset. Fix: stage windows/branding/ into the
image and re-run Apply-Branding -Mode Online from SetupComplete (post-OOBE, as
SYSTEM) where it sticks. OEM About re-asserted harmlessly.
2. sm-bootstrap account still present after onboarding — TearDownAsync's in-session
Remove-LocalUser no-ops (can't delete the account you're logged in as). Fix: keep
the best-effort in-session attempt, but DEFER the real removal to a SYSTEM
AtStartup scheduled task that runs on next boot (sm-bootstrap not logged on),
removes the account + Win32_UserProfile, then deletes itself.
(Network 'no adapter' in the VM was a Proxmox NIC-model regression to virtio — fixed
by switching the VM to Intel e1000; not a SilverMetal change.)
