When you install Horizon Agent on an unmanaged machine, you can select or deselect certain 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 Unmanaged Machines in an IPv4 Environment (Optional)
Option Description
USB Redirection Gives users access to locally connected USB devices on their desktops.

USB redirection is supported on remote desktops that are deployed on single-user machines. In addition, redirection of USB flash drives and hard disks is supported on RDS desktops and applications.

This setup option is not selected by default. You must select the option to install it.

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

Client Drive Redirection Allows Horizon Client users to share local drives with their remote desktops.

After this setup option is installed, no further configuration is required on the remote desktop.

Client Drive Redirection is also supported on VDI desktops that run on managed, single-user virtual machines and on RDS desktops and applications.

View Persona Management Synchronizes the user profile on the local desktop with a remote profile repository, so that users have access to their profiles whenever they log in to a desktop.
Smartcard Redirection Lets users authenticate with smart cards when they use the PCoIP or Blast Extreme display protocol.

Smartcard Redirection is supported on remote desktops that are deployed on single-user machines but is not supported on RDS host-based remote desktops.

Virtual audio driver Provides a virtual audio driver on the remote desktop.

In an IPv6 environment, the only optional feature is Smartcard Redirection.
