Table 7-1. Horizon Policies
Policy Description
Multimedia redirection (MMR) Determines whether MMR is enabled for client systems.
MMR is a Windows Media Foundation filter that forwards multimedia data from
specific codecs on remote desktops directly through a TCP socket to the client
system. The data is then decoded directly on the client system, where it is
played.
The default value is Deny.
If client systems have insufficient resources to handle local multimedia
decoding, leave the setting as Deny.
Multimedia Redirection (MMR) data is sent across the network without
application-based encryption and might contain sensitive data, depending on
the content being redirected. To ensure that this data cannot be monitored on
the network, use MMR only on a secure network.
USB Access Determines whether remote desktops can use USB devices connected to the
client system.
The default value is Allow. To prevent the use of external devices for security
reasons, change the setting to Deny.
PCoIP hardware acceleration Determines whether to enable hardware acceleration of the PCoIP display
protocol and specifies the acceleration priority that is assigned to the PCoIP
user session.
This setting has an effect only if a PCoIP hardware acceleration device is
present on the physical computer that hosts the remote desktop.
The default value is Allow at Medium priority.
Using
Horizon 7 Group Policy Administrative Template Files
Horizon 7 provides several component-specific Group Policy Administrative ADMX template files.
You can optimize and secure remote desktops and applications by adding the policy settings in
the ADMX template files to a new or existing GPO in Active Directory.
All ADMX files that provide group policy settings for Horizon 7 are available in VMware-
Horizon-Extras-Bundle-x.x.x-yyyyyyy.zip, where
x.x.x
is the version and
yyyyyyy
is
the build number. You can download the file from the VMware Downloads site at https://
my.vmware.com/web/vmware/downloads. Under Desktop & End-User Computing, select the
VMware Horizon 7 download, which includes the ZIP file.
The Horizon 7 ADMX template files contain both Computer Configuration and User Configuration
group policies.
n The Computer Configuration policies set policies that apply to all remote desktops, regardless
of who connects to the desktop.
n The User Configuration policies set policies that apply to all users, regardless of the remote
desktop or application they connect to. User Configuration policies override equivalent
Computer Configuration policies.
Microsoft Windows applies policies at desktop startup and when users log in.
