Horizon 7 includes several component-specific group policy administrative (ADMX) template files.
All ADMX files that provide group policy settings for Horizon 7 are available in a bundled .zip file named 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 download site at https://my.vmware.com/web/vmware/downloads. Under Desktop & End-User Computing, select the VMware Horizon 7 download, which includes the bundled .zip file.
You can optimize and secure remote desktops by adding the policy settings in these files to a new or existing GPO in Active Directory and then linking that GPO to the OU that contains your desktops.
See the View Administration and Configuring Remote Desktop Features in Horizon 7 documents for information on using Horizon 7 group policy settings.
