You can use Remote Desktop Services group policies to control the configuration and performance of RDS hosts and published desktop and application sessions. Horizon 7 provides an ADMX file that contains the Microsoft RDS group policies that are supported in Horizon 7.
As a best practice, configure the group policies that are provided in the Horizon 7 ADMX file rather than the corresponding Microsoft group policies. The Horizon 7 group policies are certified to support your Horizon 7 deployment.
