Meltdown / Spectre Reg key question RRS feed

  • Question

  • Is it safe to install the Spectre / Meltdown reg keys before the patch is installed? are there any known side effects for doing so.

    There are the reg keys from windows-server-guidance-to-protect-against-the-speculative-execution

    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

    reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization" /v MinVmVersionForCpuBasedMitigations /t REG_SZ /d "1.0" /f 

    Any help is much appreciated.
