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".
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
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.
could you remind us how to check in eveent panel about lsa? thanks
and that's what Microsoft advises and there are supporters in favor of this attitude, but there are other specialists who recommend to create these 2 registry values RunAsPPL and RunAsPPLBoot in D Word 32 bits by giving them a value of 2 and who say that if you don't, there is no kernel protection.
No one can affirm or prove 100% what is best in terms of security, so we are all in a dark smoke.
Microsoft have published details on how to check whether LSA protection is enabled, using the Event Viewer. The registry edit is not necessary to enable LSA protection.
Hello Cory Royce,
You sayd " Microsoft have explicitly told people not to apply any workarounds other than clicking dismiss " ,

If I understood correctly then, they do not recommend doing this procedure:
- Open Windows Registry Editor.
- Navigate to the following location: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
- Make sure you have RunAsPPL and RunAsPPLBoot. entries. If you don’t have RunAsPPLBoot listed, create DWORD entries for RunAsPPL and RunAsPPLBoot.
Microsoft have explicitly told people not to apply any workarounds other than clicking dismiss.
