Check for Windows 11 Core Isolation issues.
Local Security Authority Protection was disabled despite being enabled, and restarting the PC didn’t resolve the issue. It seems this setting is new to Windows 11 and wasn’t listed in Core Isolation earlier. Notifications are now being shown even when the option is off. I’m confused about how it shows up suddenly in the list—it shouldn’t appear that way with the stable release version I’ve been using, and I haven’t seen it before.
I turned it on, but I haven’t noticed the Local Security Authority Protection option until Memory Integrity appeared in the list. Even after enabling that protection, it remains disabled, and I’m still seeing the issue. It keeps showing as off even after restarts.
The necessary registry records might be absent. Clicking the more info link under the Defender item will direct you to the MS page that explains the setting and displays the registry key you can add to resolve the problem. I think a recent antimalware or Defender update could be causing the warning, possibly introducing a bug.
Add the key under the specified path with the desired value to disable the reboot prompt.
