RDS Host Performance Options

options. By default, Horizon 7 disables certain performance options for RDS hosts for all supported versions
of Windows Server.
The following table shows the performance options that are disabled by Horizon 7.

The five performance options that are disabled by Horizon 7 correspond to four Horizon 7 settings in the
registry. The following table shows the Horizon 7 settings and their default registry values. The registry
values are all located in the registry subkey HKEY_LOCAL_MACHINE\Software\VMware, Inc.\VMware
VDM\Agent\Configuration. You can re-enable the performance options by setting one or more of the Horizon
7 registry values to false.
