Windows Security Bug - Local Security Authority Protection Not Registering a System Restart

Question

After I uninstalled Avira Antimalware, I got an alert from Windows Security that my Local Security Authority Protection was turned off. But after I turned it on and restarted as instructed, I continue to get the same alert that my Local Security Authority Protection is turned off, even though within the same window, the toggle switch under the "Local Security Authority Protection" heading displays that it's already turned on.

Additionally, at the same time that this bug appeared, I've also started to get an old Windows bug where if I try to open File Explorer from the taskbar, the entire taskbar would crash and restart every time (though I can open File Explorer from the Start menu without issue).

Any help resolving either bug would be appreciated. Thanks.

Answer 1

I figure that is a missing reg entry RunAsPPLBoot in my case.

Create a new DWORD32 and set to 2

After reboot no longer get error.

RunAsPPL and RunAsPPLBoot.

By default they are set to 0 to enable this you need to set them to 2.

Also set group policy as enable for uefi lock only , my problem is fixed now, no need to reset windows.

In the Local Group Policy Editor window, navigate to the following path: Computer Configuration\Administrative Templates\System\Local Security Authority.

In the right panel, double-click on the ‘Configure LSASS to run as a protected process‘ policy.

In the policy settings window, select the Enabled option

Then click on the dropdown under Configure LSA to run as a protected process and select Enabled with UEFI Lock

Did you try reset app?

Did you try enable policy?

Check if the other reg entry has 0,1 ou 2 value.
