VMware Horizon – Upgrade Horizon GPO Bundle to v. 2312

Release date: January 30th 2024

Welcome to my VMware Horizon series. In this session I will describe how I upgraded my VMware Horizon GPO Templates to v.2312. According to the VMware Horizon 8 2312 Release Notes, these are the changes to the Horizon GPO Templates:

• You can configure file filter for drag and drop redirection when you set the group policy Configure file filter for drag and drop.
• Blast uses build-to-lossless mode, which results in the highest display quality when you set the group policy Build to Lossless.
• You can set the group policy Synthetic Keystroke Blocking to block client endpoints from sending potentially malicious, synthetic keystrokes to remote desktops and applications.

Upgrading the GPO templates is done as step 12 in the supported update sequence.

I start out by downloading the Horizon GPO Bundle from VMware Customer Connect

Previously I’ve done this manually, but this time I will be doing the admx-upgrade from my management server, using the PowerShell script below. The workflow of the script is as follows:

Prerequisites:

• Permissions to write to SYSVOL PolicyDefinitions folder
• Run script in Administrative Powershell session

Hz-copyAdmx.ps1

# Horizon Admx Upgrade script

$installDir = "C:Install"
New-Item -Path $installDir -type directory -Force

$HzBundle = "<network-path>VMware-Horizon-Extras-Bundle*.zip"
Expand-Archive -Path $HzBundle -DestinationPath $installDir

$admxDestination = '<network-path>PolicyDefinitions'

Copy-Item -Path $installDir*.admx -Destination $admxDestination -Recurse -Force
Copy-Item -Path $installDiren-US*.adml -Destination $admxDestinationen-US -Recurse -Force

Remove-Item –path $installDir –Recurse -Force

This concludes my session about upgrading the Horizon GPO Templates to v. 2312. According to the supported upgrade path from VMware, this is the final step in upgrading VMware Horizon. With this done, I can log in and test that everything works as expected.
