If a user has never connected to a desktop on an RDS host, and the user launches an application that is hosted on the RDS host, the Windows basic theme is not applied to the application even if a GPO setting is configured to load the Aero-styled theme. Horizon 7 does not support the Aero-styled theme but supports the Windows basic theme. To make the Windows basic theme apply to the application, you must configure another GPO setting.
Verify that the Group Policy Management feature is available on your Active Directory server.
