Napísal som skript v PowerShell, ktorý ma zaúlohu pomôcť v inventarizácií majetku

Zisťuje:

Hostname
Serial Number (SN)
RAM, aká je momentalne použitá a do akej kapacity ju môžeme rozšíriť
TMP modul
Stav batérie
Disk – model a kapacita
a na konci urobí report v html formáte

Príprava skriptu:

Vytvoríme priečinok na disku C a pomenujeme ho Tools

C:\Tools

Tu vytvoríme TXT súbor a pomenujeme ho: system_info.ps1

Vložíme skript

# system_info.ps1
Clear-Host
Write-Host "=== SYSTEM INFORMATION ===" -ForegroundColor Cyan

# SYSTEM

$computer = Get-CimInstance Win32_ComputerSystem
$os = Get-CimInstance Win32_OperatingSystem

Teraz ho uložíme

Aby sa nam skript dal spustiť, tak musíme prepísať príponu z txt na ps1

Vo Windows 11 klikneme na View
