# Nombre del Script: hw_auditoria.ps1
# Función: Captura hardware esencial (Serial, CPU, RAM, Disco, SO) y lo copia al portapapeles en formato JSON.

# ==============================================================================
# 1. CAPTURA DE DATOS DEL SISTEMA
# ==============================================================================

# 1.1 Información de la Placa Base (para el serial)
try {
    $BiosInfo = Get-CimInstance -ClassName Win32_BIOS -ErrorAction Stop | Select-Object -ExpandProperty SerialNumber
    $SystemInfo = Get-CimInstance -ClassName Win32_ComputerSystem -ErrorAction Stop | Select-Object Manufacturer, Model
} catch {
    $BiosInfo = "N/A"
    $SystemInfo = @{ Manufacturer="N/A"; Model="N/A" }
}

# 1.2 Información del CPU
$CpuInfo = Get-CimInstance -ClassName Win32_Processor | Select-Object -ExpandProperty Name | Select-Object -First 1

# 1.3 Obtener RAM total (convertir de bytes a GB)
$RamBytes = (Get-CimInstance -ClassName Win32_PhysicalMemory | Measure-Object -Property Capacity -Sum).Sum
if ($RamBytes) {
    $RamGB = [math]::Round($RamBytes / 1GB, 0)
    $RamValue = "$RamGB GB"
} else {
    $RamValue = "N/A"
}

# 1.4 Obtener información del disco principal (asumimos C:)
try {
    $DiskInfo = Get-CimInstance -ClassName Win32_LogicalDisk -Filter "DeviceID='C:'" -ErrorAction Stop | Select-Object -ExpandProperty Size
    $DiskGB = [math]::Round($DiskInfo / 1GB, 0)
    $DiskValue = "$DiskGB GB"
} catch {
    $DiskValue = "N/A"
}

# 1.5 Obtener Sistema Operativo
$OsInfo = Get-CimInstance -ClassName Win32_OperatingSystem | Select-Object -ExpandProperty Caption

# ==============================================================================
# 2. CONSTRUCCIÓN Y TRANSFERENCIA JSON
# ==============================================================================

# 2.1 Construir el objeto de resultados
$HardwareData = @{
    serial = $BiosInfo
    brand = $SystemInfo.Manufacturer
    model = $SystemInfo.Model
    cpu = $CpuInfo.Trim()
    ram = $RamValue
    disk = $DiskValue
    os = $OsInfo
}

# 2.2 Convertir a JSON
$JsonData = $HardwareData | ConvertTo-Json -Depth 5 -Compress

# 2.3 Copiar al portapapeles
$JsonData | Set-Clipboard

# 2.4 Mostrar mensaje de éxito al usuario (en la consola)
