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.)

SilverMetal
Privacy-hardened devices for users who want their privacy back — on whatever platform they have.
SilverMetal is SilverLABS' cross-platform privacy-hardening program. We don't believe in "one true OS" — we meet users on the platform they actually use, and give them the strongest hardening that platform physically allows. Honestly labelled, no marketing fluff.
Two product lines
The SilverMetal program ships two distinct product lines, named to make their scope obvious to buyers:
🔒 SilverMetal OS
We ship the operating system or ROM. Full kernel-level control, our verified-boot key, our update channel. Strongest possible hardening.
- SilverMetal OS — Linux (Debian/Kicksecure-based ISO) — Tier A
- SilverMetal OS — Pixel (GrapheneOS-fork ROM) — Tier B
- SilverMetal OS — Samsung (LineageOS-fork ROM, unlocked-bootloader models) — Tier C
- SilverMetal OS — Motorola (DivestOS/LineageOS-fork ROM) — Tier C
🛡️ SilverMetal Enhanced
We harden the OS your device already runs. Configuration profiles, hardening installers, the SilverLABS Application Stack. For users who can't or won't replace their OS.
- SilverMetal Enhanced — Windows (LTSC IoT installer + hardening + Stack) — Tier C
- SilverMetal Enhanced — macOS (signed config profile + setup script + Stack) — Tier C-D
- SilverMetal Enhanced — iOS (MDM profile + Stack) — Tier D
- SilverMetal Enhanced — Android (generic profile + Stack on existing Android) — Tier D
Tiers explained in docs/platform-matrix.md.
What every SilverMetal device gets
Both lines ship the SilverLABS Application Stack — a suite of cross-platform privacy apps that replace the cloud services your device normally talks to (Google, Apple, Microsoft):
| Component | Status | Purpose |
|---|---|---|
| SilverBrowser | v1 (Linux MVP) | De-Googled, telemetry-free, fingerprint-resistant browser |
| SilverVPN | Existing — see SilverLABS/SilverVPN |
Always-on, no-logs VPN with our own infrastructure |
| SilverSync | v1 (Linux MVP) | Private replacement for iCloud / Google Drive / OneDrive |
| SilverChat | Existing — SilverVPN.Client.Chat, Signal Protocol over VPN transport. Promoted from v1.1 to v1 |
E2EE messenger |
| SilverDuress | v1.1 | Duress password / panic-wipe / anti-coercion |
| SilverKeys | v1.1 | Zero-knowledge password + 2FA manager |
Two ways to get SilverMetal
Every flavour — OS or Enhanced — supports both buyer modes:
"I'm choosing a new device"
Buy a preflashed SilverMetal SKU. We've done all the work; it arrives ready.
"I already own a device and want to harden it"
Download the free SilverLABS Stack + the SilverMetal OS or Enhanced package for your platform. Apply it yourself. Same software, same hardening, no hardware lock-in.
