In the "Setting up virtual desktops in Horizon 7" PDF on page 23 it says to change Window Firewall Service settings to restart after a failure. All of the settings in the Windows Defender Firewall service are greyed out. I tried shutting off User Account Control and rebooting, I tried shutting off real time protection for Windows Defender... no luck. I am logged in as the local administrator and this master image is not joined to the domain so I know it is not an Active Directory group policy over writing it.
When I try changing the service settings using the SC command I get....
[SC] OpenService FAILED 5:
