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 8 Administration and Horizon Remote Desktop Features and GPOs documents for information on using VMware Horizon 8 group policy settings.
