PowerShell – Lock Workstation

This is a great script to add to a setup script to lock the workstation after everything is done or before everything starts

Function Lock-WorkStation {
$signature = @"
[DllImport("user32.dll", SetLastError = true)]
public static extern bool LockWorkStation();
"@

$LockWorkStation = Add-Type -memberDefinition $signature -name "Win32LockWorkStation" -namespace Win32Functions -passthru
$LockWorkStation::LockWorkStation() | Out-Null
}
