Windows update done through script

You can update Windows locally using a PowerShell script. Here’s a script that automates the update process, including checking for updates, installing them, and restarting the system if necessary.

PowerShell Script for Local Windows Update

powershell# Run as administrator
$ErrorActionPreference = "Stop"

# Check if running as Administrator
function Test-Admin {
    $currentUser = [Security.Principal.WindowsIdentity]::GetCurrent()
    $principal = New-Object Security.Principal.WindowsPrincipal($currentUser)
    return $principal.IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)
}

if (-Not (Test-Admin)) {
    Write-Host "This script must be run as Administrator!" -ForegroundColor Red
    exit 1
}

# Install Windows Update module if not installed
if (-not (Get-Module -Name PSWindowsUpdate -ListAvailable)) {
    Write-Host "Installing Windows Update module..."
    Install-Module PSWindowsUpdate -Force -AllowClobber -Scope CurrentUser
}

# Import Windows Update module
Import-Module PSWindowsUpdate

# Check for updates
Write-Host "Checking for Windows Updates..."
$Updates = Get-WindowsUpdate -MicrosoftUpdate -AcceptAll

# Install updates
if ($Updates.Count -gt 0) {
    Write-Host "Installing updates..."
    Get-WindowsUpdate -Install -AcceptAll -IgnoreReboot
} else {
    Write-Host "No updates available."
}

# Prompt for restart if required
if (Get-WURebootStatus) {
    Write-Host "A restart is required. Restarting in 10 seconds..."
    Start-Sleep -Seconds 10
    Restart-Computer -Force
} else {
    Write-Host "No restart required."
}

Write-Host "Windows update process completed!" -ForegroundColor Green

How to Use:

1. Run PowerShell as Administrator
2. Save the script as update_windows.ps1
3. Execute the script:
4. powershell
5. Set-ExecutionPolicy Bypass -Scope Process -Force .\update_windows.ps1

This script:

• Ensures it’s running as an administrator
• Installs the PSWindowsUpdate module if not available
• Checks for Windows updates
• Installs updates without requiring user input
• Restarts the system if necessary
