Window11 Automatic Silent Installation

[qmaster7953]

I need help with the following script, which I need to run remotely. The script downloads the Windows 11 installation executable from the Microsoft website to upgrade a system from Windows 10 to Windows 11. I tested it locally on a Windows 10 workstation, but the issue is that the process doesn’t progress—it just gets stuck in Task Manager. I’m not sure what I might be missing, and I would really appreciate your assistance.

Set-ExecutionPolicy Bypass -Scope Process -Force

Define the upgrade folder

$FolderPath = “C:\WindowsUpgrade”

Create the folder if it does not exist

if (!(Test-Path -Path $FolderPath)) {
Write-Host “Creating Windows Upgrade Folder…”
New-Item -Path $FolderPath -ItemType Directory
}

Define the URL and download location

$DownloadUrl = “LinkedIn”
$InstallerPath = “$FolderPath\Windows11InstallationAssistant.exe”

Download the installer

Write-Host “Downloading Windows 11 Installation Assistant…”
Invoke-WebRequest -Uri $DownloadUrl -OutFile $InstallerPath

Check if the download was successful

if (Test-Path $InstallerPath) {
Write-Host “Download complete. Running installer…”
Start-Process -FilePath $InstallerPath -ArgumentList “/auto upgrade /quiet /noreboot /Compat IgnoreWarning” -Verb RunAs -Wait -NoNewWindow
Write-Host “Installation process has started.”
} else {
Write-Host “Download failed. Please check your internet connection and try again.”
}

The first internet result for this was for a Powershell script that someone wrote that does actually this. A quick glance at the script would suggest your issue isn’t Powershell related, but rather you are missing required switches for the installation assistant.

Hi @qmaster7953,

Welcome to the forums first and foremost!

When working with code, please be sure to follow this formatting to ensure all code is captured and nothing is left off:

For easy visibility, you can simply put 3 ` surrounding the code.
