📝 Notes

ZeroTier runs as a system service (ZeroTierOneService) that starts at boot — the tray icon is a separate UI process.
The node identity (public/private key + node ID) is stored in C:\ProgramData\ZeroTier\One\identity.public and identity.secret — never share identity.secret.
Network join configuration is in C:\ProgramData\ZeroTier\One\networks.d\.
ZeroTier installs a virtual network adapter visible in Device Manager and Get-NetAdapter.

# Check service status
Get-Service -Name "ZeroTierOneService" | Select-Object Name, Status, StartType

# List ZeroTier virtual adapters
Get-NetAdapter | Where-Object { $_.InterfaceDescription -like "*ZeroTier*" }

# Read node ID (first 10 chars of identity.public)
$id = Get-Content "C:\ProgramData\ZeroTier\One\identity.public" -ErrorAction SilentlyContinue
if ($id) { $id.Split(':')[0] }
