VMware Horizon 8 includes several component-specific group policy administrative (ADMX) template files.
All ADMX files that provide group policy settings for VMware Horizon 8 are available in VMware-Horizon-Extras-Bundle-YYMM-x.x.x-yyyyyyyy.zip, where YYMM is the marketing version, x.x.x is the internal version and yyyyyyyy 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 8 download, which includes the GPO Bundle containing the 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 Horizon Administration and Horizon Remote Desktop Features and GPOs documents for information on using VMware Horizon 8 group policy settings.
