Windows Server guidance to protect against speculative execution side-channel vulnerabilities

Hello,

I am working on a server security report and looking at this link: https://support.microsoft.com/en-us/help/4072698/windows-server-speculative-execution-side-channel-vulnerabilities-prot

I follow the instruction to enable mitigations for CVE-2017-5715 and applied these registry changes:

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 0 /f
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 3 /f

I run the Get-SpeculationControlSettings and see the line "Windows OS Support for branch target injection mitigation is disabled by system policy is still showing FALSE - Please see the attached.  

Anyone who knows please advise.  

Thanks.
