6. Deploying & Configuring an Instant Clone Desktop Pool

You must complete Lab 2 before starting this lab.

For a detailed step by step best practice approach to building a master image follow the guidance on Tech Zone authored by Hilko Latinga and Graeme Gordon

https://techzone.omnissa.com/resource/manually-creating-optimized-windows-images-horizon-vms

In this lab the base image has already been prepared with VMware tools installed. We will follow through on deploying All Agents required for Horizon and the OS Optimization tool. You might notice that the Master Image you are working with is already in Audit Mode. For a step by step breakdown on how this is done, review the above mentioned article on TechZone

Part 1. Deploying Dynamic Environment Manager Licensing

From Dynamic Environment Manager 2203, the MMC has to be licensed and we do not have to deploy the FlexEngine with an associated license when using NoAD mode.
For Horizon Virtual Environments the if the Horizon Agent is installed , the FlexEngine will see the environment as licensed. In non Horizon Environments where we want to use Dynamic Environment Manager, the Dynamic Environment Manager requires a license

On your ControlCenter server

Part 3. Setting and configuring the Master Image

Multiple steps are required to configure the Master Image

Our Master Image already has the VMware tools installed
Recommended Base Virtual Hardware configuration has already been completed
The Base Master Image has also been deployed in Audit Mode offering the greatest flexibility in terms of Configuration
We will run the following tasks:
1. Resolve Windows 11 Sysprep Issues
2. Deploy the Horizon Agent
3. Deploy the Dynamic Environment Manager FlexEngine
4. Run the OS Optimization tools
5. Deploy the App Volumes Agent

If you have an opportunity, follow this guide on TechZone and create your own version of the Master Image.

https://techzone.omnissa.com/resource/manually-creating-optimized-windows-images-horizon-vms

Task 1. Resolving SysPrep issues with Windows 11

Please read this Omnissa Knowledge Base related to Agent installation requirements https://kb.omnissa.com/s/article/2118048

In the vSphere Admin Console
- under Hosts & Clusters inventory
  - select W11INSTMaster

In the vSphere Admin Console
- to the right, note you are view the W11INSTMaster details
  - select the Summary tab
- in the Summary area
  - select LAUNCH WEB CONSOLE

From Microsoft Windows 22H2 onwards for both Windows 10 and 11 we have come across an issue with Sysprep. After lots of research we have found the following fix. Just something to note, there are several things in Windows 11 that causes Sysprep to fail. This is one of them. If we were to run Sysprep and we were to look at the error log in the Panther folder you would notice that Bitlocker in this case is the issue. We will process with disabling Bitlocker as part of the image preparation process.

Appx applications also cause Sysprep to fail and as part of the image preparation phase, we will execute a PowerShell command issued from our Global Support Services to mitigate an issue with freshly deployed Windows 11 base image when wanting to run Sysprep.

On the W11INSTMaster desktop
- on the System Preparation Tool 3.14
  - select Cancel

Your base image is in Audit Mode and as a result the System Preparation Tool automatically launches. We trigger Audit mode whilst installing the base image

On the W11INSTMaster desktop
- on the Taskbar
  - in the SEARCH area
    - enter Power
  - from the pop-up
    - select Windows PowerShell
  - in the Windows PowerShell area
    - select Run as administrator

In the Windows PowerShell window
- enter

Disable-BitLocker -MountPoint "C"

Click to copy

note that the Protection Status is now Off

please note, in testing this we had varying results. the decrypt process can anywhere up to minutes

On the W11INSTMaster desktop
- select the Control Panel shortcut
- in the Windows PowerShell area
  - select Open

In Control Panel
- select System and Security

In Control Panel
- under System and Security
  - select Bitlocker Drive Encryption

In Control Panel
- under Bitlocker Drive Encryption
- validate that BitLocker is off
- If its still decrypting wait for it to complete before moving onto the next step

In the Windows PowerShell console
- enter

Set-ExecutionPolicy Unrestricted

Click to copy

with your keyboard select ENTER
- If you get prompted , enter A

In the Windows PowerShell console
- enter

Get-AppxPackage -AllUsers | Where PublisherId -eq 8wekyb3d8bbwe | Remove-AppxPackage

Click to copy

with your keyboard select ENTER

What you will notice is the Windows PowerShell will execute and there will be a lot of errors occurring
The Windows PowerShell will then Bomb out
Relaunch the Windows PowerShell ,
- set the ExecutionPolicy to Unrestricted
- relaunch the above command
- you will notice on round 2, the Windows PowerShell does not quit

The purpose of fulfilling this task to remediate an APPX applications issue where some Apps are associated with individual users. This is a SysPrep issue and has to be resolved or SysPrep to work

In the Windows PowerShell window
- enter the next PowerShell string

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Click to copy

If we only executed the command in step 11. When a reboot occurs there is no Taskbar. We then run the command in step 12 to fix the Taskbar issue.
To continue with Task 2 remain on W11INSTMaster

Task 2. Installing the Horizon Agent
