Blogpost - Creating a Hyper-V VM running Evaluation versions of Windows server using PowerShell

[Harm_Veenstra]

Wrote a blogpost about how you can deploy Hyper-V VM's on your machine using PowerShell, below is the script which I made 

#Requires -RunAsAdministrator
 
#Start a stopwatch to measure the deployment time
$stopwatch = [System.Diagnostics.Stopwatch]::StartNew()
 
#Detect if Hyper-V is installed
if ((Get-WindowsOptionalFeature -FeatureName Microsoft-Hyper-V-All -Online).State -ne 'Enabled') {
    Write-Warning ("Hyper-V Role and/or required PowerShell module is not installed, please install before running this script...")
    return
}
else {
    Write-Host ("Hyper-V Role is installed, continuing...") -ForegroundColor Green
}
 
#Retrieve all Server Operating System VHD links from the Microsoft Evaluation Center
$totalcount = $null
 
$urls = @(
    'https://www.microsoft.com/en-us/evalcenter/download-windows-server-2012-r2',

    'https://www.microsoft.com/en-us/evalcenter/download-windows-server-2022'

#Loop through the urls, search for VHD download links and add to totalfound array and display number of downloads
$ProgressPreference = "SilentlyContinue"
$totalfound = foreach ($url in $urls) {
    try {

                -and $_.'aria-label' -match 'VHD'
        }
        $count = $DownloadLinks.href.Count
        $totalcount += $count
        Write-host ("Processing {0}, Found {1} Download(s)..." -f $url, $count) -ForegroundColor Green
