    Core Isolation: Local Security Authority Protection - won't turn on


    I got a Windows Security warning about my Local Security Authority protection being 'off'. I toggled it to 'on' and it said I have to restart for that to take effect. I did the restart and thought nothing of it. I didn't check that it was all good after the restart, I didn't think I needed to. I was told something wasn't right and what I should do about it and did that, never for a second thought I needed to think further about it.Now, a day later, I notice I have the same warning. This time though when I went into the settings, it's telling me it's turned off but as you can see in the screens

    :)

    Core Isolation: Local Security Authority Protection - won't turn on

    Local Security Authority protection Bug?

    Open an admin Command Prompt and run these two commands:

    • reg add "HKLM\SYSTEM\CurrentControlSet\Control\Lsa" /v "RunAsPPL" /t REG_DWORD /d 2 /f
    • reg add "HKLM\SYSTEM\CurrentControlSet\Control\Lsa" /v "RunAsPPLBoot" /t REG_DWORD /d 2 /f
    Restart Windows. That should clear the yellow exclamation warning.
