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.
i just noticed this issue today and it took research to try and find a fix, this is unacceptable from windows, users should NEVER have to make registry edits and manually fix these types of issues
For anyone with this issue, this worked for me on Win 11
Right click on start menu and select Terminal (Admin)
Copy & Paste the code below and hit enter.
Restart computer.
CODE:
reg add HKLM\SYSTEM\CurrentControlSet\Control\Lsa /v RunAsPPL /t REG_DWORD /d 2 /f;reg add HKLM\SYSTEM\CurrentControlSet\Control\Lsa /v RunAsPPLBoot /t REG_DWORD /d 2 /f;
So if I don't add the RunAsPPLBoot entry (because I don't have it), will my PC be vulnerable, or am I fine and this does just get rid of the message displaying that I should turn it on when it is On??
This totally works but it WILL disable your TPM when done!!! (Regardless of what your TPM BIOS settings are set to.)
To have everything fully functional/working correctly after making the above Registry changes you need to reboot your PC into your BIOS, fully disable your board's fTPM, and then save & exit and let Windows boot up.
Then after Windows has fully booted, reboot the PC back into the BIOS one last time and re-enable the board's fTPM, then save & exit. This should have the TPM fully enabled & functional again in Windows once it boots up, which can be quickly verified by checking the "Device security" tab of the Windows Security settings menu.
