When you install Horizon Agent on an RDS host, you can select custom setup options. In addition, Horizon Agent installs certain features automatically on all guest operating systems on which they are supported. These features are not optional.

To change custom setup options after you install the latest Horizon Agent version, you must uninstall and reinstall Horizon Agent. For patches and upgrades, you can run the new Horizon Agent installer and select a new set of options without uninstalling the previous version.

Table 1. Horizon Agent Custom Setup Options for an RDS Host in an IPv4 Environment
Option Description
USB Redirection Gives users access to locally connected USB storage devices.

Specifically, redirection of USB flash drives and hard disks is supported in published desktops and published applications. Redirection of other types of USB devices, and other types of USB storage devices such as security storage drives and USB CD-ROM, is not supported in published desktops and published applications.

This setup option is not selected by default. You must select the option to install it. This option is available on RDS hosts that run Windows Server 2012 or 2012 R2 but not Windows Server 2008 R2.

For information about using USB redirection securely, see the Horizon 7 Security document. For example, you can use group policy settings to disable USB redirection for specific users.

HTML Access Enables users to connect to published desktops and published applications by using HTML Access. The HTML Access Agent is installed when this setup option is selected. This agent must be installed on RDS hosts to enable users to make connections with HTML Access
3D RDSH Provides 3D graphics support to applications that run on this RDS host.
View Composer Agent Select this option if this machine is a parent virtual machine for the creation of an automated farm. Do not select this option if this machine is an RDS host in a manual farm.
Client Drive Redirection Enables Horizon Client users to share local drives with their published desktops and published applications.

After this setup option is installed, no further configuration is required on the RDS host.

Client drive redirection is also supported on remote desktops that run on single-user virtual machines and on unmanaged machines.

Table 2. Horizon Agent Features That Are Installed Automatically on an RDS Host
Feature Description
PCoIP Agent Enables users to use the PCoIP display protocol to connect to applications and published desktops.
Windows Media Multimedia Redirection (MMR) Provides multimedia redirection for published desktops. This feature delivers a multimedia stream directly to the client computer, which enables the multimedia stream to be processed on the client hardware instead of on the remote ESXi host.
Unity Touch Enables tablet and smart phone users to interact with Windows applications that run on the remote desktop. Users can browse, search, and open Windows applications and files, choose favorite applications and files, and switch between running applications without using the Start menu or Taskbar.
PSG Agent Installs the PCoIP Secure Gateway on RDS hosts to implement the PCoIP display protocol for desktop and application sessions that run on RDS hosts.
VMwareRDS Provides the VMware implementation of Remote Desktop Services functionality.
HTML5 Multimedia Redirection Redirects HTML5 multimedia content in a Chrome or Edge browser to the client for performance optimization.
Browser Redirection Renders a website on the client system instead of the agent system, and displays the website over the remote browser's viewport, when a user uses the Chrome browser in a remote desktop.

In an IPv6 environment, the automatically installed features are PCoIP Agent, PSG Agent, and VMwareRDS.

For additional features that are supported on RDS hosts, see "Feature Support Matrix for Horizon Agent" in the Horizon 7 Architecture Planning document.
