update - I can't enable the Meltdown/Spectre mitigations in Windows Server 2008 R2

I have installed the patch released today as detailed here and then set the two registry keys as mentioned:

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

However, when I run the provided PowerShell module to check, it is informing me the mitigations are still not enabled:

PS C:\Users\Administrator> get-speculationcontrolsettings
Speculation control settings for CVE-2017-5715 [branch target injection]

Hardware support for branch target injection mitigation is present: False
Windows OS support for branch target injection mitigation is present: False

Windows OS support for branch target injection mitigation is enabled: False

Speculation control settings for CVE-2017-5754 [rogue data cache load]

Hardware requires kernel VA shadowing: True
Windows OS support for kernel VA shadow is present: False
Windows OS support for kernel VA shadow is enabled: False

Suggested actions


 * Install BIOS/firmware update provided by your device OEM that enables hardware support for the branch target injection mitigation.
 * Install the latest available updates for Windows with support for speculation control mitigations.
 * Follow the guidance for enabling Windows support for speculation control mitigations are described in https://support.microsoft.com/help/4072698


BTIHardwarePresent             : False
BTIWindowsSupportPresent       : False
BTIWindowsSupportEnabled       : False
BTIDisabledBySystemPolicy      : False
BTIDisabledByNoHardwareSupport : False

KVAShadowRequired              : True
KVAShadowWindowsSupportPresent : False
KVAShadowWindowsSupportEnabled : False
KVAShadowPcidEnabled           : False

Why is this? What else do I have to do? I have rebooted the server for good measure with no improvement.

Update after answer from @Paul:

I've now installed the correct update (wally), and this is the output of the PowerShell cmdlet:

PS C:\Users\Administrator> get-speculationcontrolsettings
Speculation control settings for CVE-2017-5715 [branch target injection]

Hardware support for branch target injection mitigation is present: False
Windows OS support for branch target injection mitigation is present: True
Windows OS support for branch target injection mitigation is enabled: False
Windows OS support for branch target injection mitigation is disabled by system policy: True
Windows OS support for branch target injection mitigation is disabled by absence of hardware support: True

Is this everything I can do pending a microcode update?
