This PowerShell script downloads the Visual C++ Redistributable for Visual Studio 2017 (x64) to the temporary directory, installs it silently, and then removes the downloaded installer file. It's intended to be run as a system script.

```powershell
$uri = [uri]::new( 'https://aka.ms/vs/17/release/vc_redist.x64.exe' );
$file = "$env:TEMP\{0}" -f $uri.Segments[-1];
[System.Net.WebClient]::new().DownloadFile( $uri, $file );
Start-Process -FilePath $file -ArgumentList '/quiet /norestart' -Wait;
Remove-Item -LiteralPath $file -ErrorAction 'SilentlyContinue';

### Download and install Brave browser from GitHub

Source: https://schneegans.de/windows/unattend-generator/samples

This script runs when the first user logs on. It fetches the latest Brave browser release URL from GitHub, downloads the installer, and installs it for all users.

```powershell
$user = 'brave';
$repository = 'brave-browser';

$uri = $( 
    & { 
        $ProgressPreference = 'SilentlyContinue';
        Invoke-WebRequest -Uri "https://api.github.com/repos/${user}/${repository}/releases?per_page=100" -UseBasicParsing -Headers @{
            Accept = 'application/vnd.github.v3+json';
        } | Select-Object -ExpandProperty 'Content' | ConvertFrom-Json;
    } 
) | ForEach-Object -Process {
    if( $_.draft -or $_.prerelease ) {
        return;
    }
    foreach( $b in ( $_.assets.browser_download_url -match 'StandaloneSetup\.exe$' ) ) {
        return [uri]::new( $b );
    }
} | Select-Object -First 1;
    
if( -not $uri ) {
    throw 'Cannot determine URL of latest Brave installer.';
}

$file = "${env:TEMP}\{0}" -f $uri.Segments[-1];
[System.Net.WebClient]::new().DownloadFile( $uri, $file );

This script handles the Windows PE stage of an unattended installation. It sets the keyboard layout, locates installation media, loads drivers, partitions and formats the disk, applies the Windows image, configures boot settings, and copies necessary files. It also includes steps to disable 8.3 file names, disable Windows Defender, and set the device setup region.
