In recent updates of Windows 11, you may not see this option in Windows Security.

As I noticed in the Oct 2023 update, this option is no longer seen in the Pro version.

This problem was resolved in the May update of Windows 11.

But LSA not visible is a different problem compared to disabled warning.

Both are different errors.

In some cases the LSA runs in the background, but is not visible in Windows Security or Defender.

In such cases you could delete the latest update and verify if it is visible.

As long as your machine is secure, you dont have to worry.

The only thing is that Windows Security should have a green tick mark in the system tray.

It indicates that all the security processes are running properly and not having any problem.

It does this by isolating the LSA process in memory to block attempts to inject code or modify data.

This protects your credentials and critical system components from credential theft attacks.

Why Does the LSA Protection Get Disabled on Windows 11?

The good news is that this can be easily remediated using one of several methods.

Microsoft periodically releases patches that fix issues with LSAprotectiongetting erroneously disabled.

Running DISM and SFC scans can detect and repair broken system files that may be causing this.

DISM scan repairs the Windows image while SFC scan fixes system file errors.

Here are the steps:

These registry modifications will enable LSA protection for both the boot and runtime environments.

you’ve got the option to now verify protection is re-enabled in the Windows Security app.

This uses Group Policy to turn on virtualization security features including LSA protection.

Conclusion

Thankfully, there are multiple straightforward methods to re-enable LSA protection.

Just be sure to first confirm the error is genuine and not a false flag.
