If you have a Windows 11 computer and find that your Local Security Authority protection is turned off, and Windows won't turn it back on, no matter how many times you restart the system. There is a simple registry edit you can make to get things working again!
Inside the registry editor, in the list on the left side, navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
Once there, right-click anywhere on the list on the right side to bring up the context menu. Select New>DWORD (32-bit). Make sure you don't click QWORD (64-bit) by accident. If you're seeing a list that says "Modify" and some other options, left-click anywhere on the white space in the list to deselect whatever is selected there and right-click again.
Now name the new entry "RunAsPPLBoot", then right-click the "RunAsPPLBoot" entry and click Modify. The "Value" box should already be highlighted, enter 2 and click OK. Close the registry editor without modifying anything else, and restart your computer.
