The Local Security Authority protection is off - Windows 11 Home

Anonymous

A yellow triangle appeared on the Windows Security iron yesterday. It says that Local Security Authority protection is off. Your device may be vulnerable.

I can press Go to settings or Dismiss but when I click go to settings, a notification saying "the page You want to access doesn't contain required functions and is unavailable". 

There is also no option to turn the protection on in the Device Security panel (there is only "dismiss" option).

When I was looking at it yesterday, there was also a notification that "The tpm module is unavailable" but today it doesn't show. I checked the device manager and uefi and both say that the tpm is enabled.

I've found an advice to turn on SMV in UEFI (in the CPU settings) to solve the problem but I don't want to change anything in BIOS without consultation as I'm no expert. I've also found a reply from a truste source that this whole problem is a Microsoft bug and it's better to just wait till they fix it.

What should I do?

Screenshots are in Polish, I hope they can be useful somehow. The first one shows the notification about a page being not available and the second shows the Device security panel (the notification from the first screenshot displays when I close the device security page or when I click on "go to settings" below the information that the protection is turned off). There is also an information (second screenshot) that "standard device security is not supported".

Microsoft have just posted that they have resolved the "Local Security Authority protection is off" issue in an update. Has anyone tried to apply it from Windows Update?

Resolution: This issue was resolved in an update for Windows Security platform antimalware platform KB5007651 (Version 1.0.2306.10002). If you would like to install the update before it is installed automatically, you will need to check for updates.

    I'd love to wait for the next windows update for this to be fixed. HOWEVER, this was first reported 2 YEARS AGO and there have 8 MAJOR updates since then and it's STILL not fixed.

    1. Open Windows Registry Editor.
    2. Navigate to the following location: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
    3. Make sure you have RunAsPPL and RunAsPPLBoot. entries. If you don’t have RunAsPPLBoot listed, create DWORD entries for RunAsPPL and RunAsPPLBoot.
    4. Value for both entries should be 2.
    5. Reboot and warnings should stop.

    This worked for me perfectly. Thank you!!!!

    I DONT HAVE RunAsPPL value in the right pane. HELP. MY PC IS UNDER ATTACK BECAUSE MICROSOFT CANT DO ITS JOB RIGHT. AND IS JUJST ROBBING ME THE LAST 4 YEARS

    TOPIC IS -I think there's an issue with LSA in the latest updates. There are a lot of users reporting it in the feedback hub. If you press Windows + F this and then search "Local Security Authority" you will see the reports submitted just a couple of hours ago.

    You can still try to force this through the registry by following the method below, but if it fails as well, we may need to wait for MS to fix this.

    1. Open the Run dialog box by pressing the Win + R hotkeys.
    2. In the Run dialog box, type regedit and click OK.
    3. Navigate to the following location:
      Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
    4. Click on the Lsa key in the left panel.
    5. Right-click on the RunAsPPL value in the right pane.
    6. Choose Edit from the context menu.
    7. Type 1 in the value data and click OK.
    8. Restart the computer

    Have a wonderful day/evening!

    I DONT HAVE RunAsPPL value in the right pane

    If you prefer not to (or cannot) edit the Registry, this web page also has a simple Powershell script you can copy and paste in Powershell to make the settings:

    Looks like adding the two entries with a hex value of 2 did the trick; the warning triangle in the Windows Security taskbar icon is gone. Thank you!!
