Do you want to deploy an Azure Virtual Desktop – Host pools quickly and want a starting point for a golden image? Look no further in this blog post. I will show you how to create a golden image using PowerShell in no more than 10 min.

I will break down the code block into smaller chunks first to explain the critical bits, and in the end, I will post the entire code block that can be run all at once. In this way, explaining block by block becomes easier than pasting one single block.

Pre-requisites

Following are the pre-requisites before you begin

• PowerShell 5.1 and above
• Azure Subscription
• Permissions within the Auzre Subscription for Azure Compute
• Assumption
  • You have an existing Resource Group (RG)
  • You have an existing Azure Virtual Network (VNET)
  • You have an existing workload subnet within the VNET
  • Identify the VM Size you will be using for the golden image
• Azure PowerShell Modules

Sign to Azure

To start working with Azure PowerShell, sign in with your Azure credentials.

Connect-AzAccount

Identify the Windows 11 Multi-session (Marketplace Image)

There are many different versions of Windows 11 marketplace images from Microsoft. Let’s identify what is available within the gallery.

Get-AzVMImageSku -Location australiaeast -PublisherName MicrosoftWindowsDesktop -Offer windows-11

#Bonus Information

If you want the Multi-session gallery image with Office, than use the following command

Get-AzVMImageSku -Location australiaeast -PublisherName MicrosoftWindowsDesktop -Offer office-365

We are going to use the Windows 11 22H2 Mutli-session – win11-22h2-avd within this script

Variable Region

Delcare all the variable within this section. Lets take a look at what we are declaring within the script:

• Existing Resource Group within the Azure Subscription (AZ104-RG)
• A location where you are deploying this virtual machine (Australia East)
• Name of the golden image virtual machine (VM03)
• NIC Interface name for the virtual machine (VM03-nic)
• RG of the VNET (In my case they are same AZ104-RG, they can be seperate too and hence a independent variable)
• Name of the existing subnet within the vNET (AZ104-VDI-Workload-L1)
• Name of the existing VNET (AZ104-RG-vnet)
• Mapping of the exisitng VNET
• Mapping of the existing subnet
• T-shirt size of the golden image we are deploying (Standard_D2s_v3)
• Gallery details of the image
  • Published – MicrosoftWindowsDesktop
  • Offer – windows-11
  • SKU – win11-22h2-avd
  • version – Offcourse latest
• Get credentials – A local admin account is created on the golden image (A input box to capture the uisername and password)

# Existing Resource Group to deploy the VM
$rgName = "AZ104-RG"

# Geo Location to deploy the VM
$location = "Australia East"

# Image template name
$vmName = "VM03"

# Networking Interfance Name for the VM
$nicName = "$vmName-nic"

# Resource Group for VNET
$vnetrgName = "AZ104-RG"

# Existing Subnet Name
$Existsubnetname = "AZ104-VDI-Workload-L1"

# Existing VNET Name
$Existvnetname = "AZ104-RG-vnet"

# Existing VNET where we are deploying this Virtual Machine
$vnet = Get-AzVirtualNetwork -Name $Existvnetname -ResourceGroupName $vnetrgName

# Existing Subnet within the VNET for the this virtual machine
$subnet = Get-AzVirtualNetworkSubnetConfig -Name $Existsubnetname -VirtualNetwork $vnet

# T-shirt size of the VM
$vmSize = "Standard_D2s_v3"

# Gallery Publisher of the Image - Microsoft
$publisher = "MicrosoftWindowsDesktop"

# Version of Windows 10/11
$offer = "windows-11"

# The SKY ending with avd are the multi-session
$sku = "win11-22h2-avd"

# Choosing the latest version
$version = "latest"

# Setting up the Local Admin on the VM
$cred = Get-Credential `
   -Message "Enter a username and password for the virtual machine."

Execution block

Execution code block within this section. Lets take a look at what we are we executing within the script:

• First its creating the network interface for the virtual machine (VM03)
• Next, under the variable $VM all virtual machine configurations
  • Tshirt size of the virtual machine
  • Credentials for the local admin (username/password)
  • The network interface assignment along with the delete option (Note delete option is essential or/else during deletion of VM it will not delete the network interface)
  • The gallery image, sku, offer from the Microsoft Market Place gallery
  • The os disk assignment along with the delete option (Note delete option is essential or/else during deletion of VM it will not delete the disk)
  • The configuration around “Trusted Platform” and enabling of TPM and Secure Boot
  • The final command to create the virtual machine with all the above configurations

# Create New network interface for the virtual machine
$NIC = New-AzNetworkInterface -Name $nicName -ResourceGroupName $vnetrgName -Location $location -Subnet $subnet

# Creation of the new virtual machine with delete option for Disk/NIC together
$vm = New-AzVMConfig -VMName $vmName -VMSize $vmSize 

$vm = Set-AzVMOperatingSystem `
   -VM $vm -Windows `
   -ComputerName $vmName `
   -Credential $cred `
   -ProvisionVMAgent `
   -EnableAutoUpdate 

# Delete option for NIC

   -EnableVtpm $true `
   -EnableSecureBoot $true 

New-AzVM -ResourceGroupName $rgName -Location $location -VM $vm

Final Script

Here I will paste the entire script block for seamless execution in single run. Following is the link to my Github for this script – Create Virtual Machine with Trusted Platform and Delete disk/nic options.

# Step 1: Import module
#Import-Module Az.Accounts

# Connect to the Azure Subcription
#Connect-AzAccount

# Get existing context
$currentAzContext = Get-AzContext

# Your subscription. This command gets your current subscription
$subscriptionID=$currentAzContext.Subscription.Id

# Command to get the Multi-session Image in Gallery
# Details from this command will help in filling out variables below on Gallery Image
# Get-AzVMImageSku -Location australiaeast -PublisherName MicrosoftWindowsDesktop -Offer windows-11

# Existing Resource Group to deploy the VM
$rgName = "AZ104-RG"

# Geo Location to deploy the VM

# Creation of the new virtual machine with delete option for Disk/NIC together
$vm = New-AzVMConfig -VMName $vmName -VMSize $vmSize

   -CreateOption "FromImage" `
   -DeleteOption "Delete"

# The sauce around enabling the Trusted Platform

   -EnableVtpm $true `
   -EnableSecureBoot $true 

New-AzVM -ResourceGroupName $rgName -Location $location -VM $vm

Note – It will give you a pop-up box for entering the username and password for the local account, and in under 10 mins you will see your virtual machine within the Azure portal

Next Steps on Golden Image

Now that the virtual machine is ready following are the next steps involved:

• Using Azure Bastion console and installing all the required applications
• Generalize and sysprep and shutdown the image
• Capture the image to the Azure Compute Galleries
• Deploy within the Azure Virtual Desktop

I hope you will find this helpful information for deploying a golden image within Azure – Virtual Machine to deploy the Azure Virtual Desktop – Host Pools. If you want to see a Powershell version of the host pool activities, leave me a comment below or on my socials. Please let me know if I have missed any steps or details, and I will be happy to update the post.

Thanks,
