The Local Security Authority protection on your Windows 11 PC is a crucial process that keeps your credentials secure. The idea behind LSA is to ensure that no loopholes in your security allow a third party to intercept your personal information. It is a process that authenticates the genuineness of your credentials before allowing you access to the system.
While the effectiveness of the process is proven, there are times when a user finds the feature toggled off on the system. Sometimes, it is manually turned off because of the heavy nature of the process, while other times, it is toggled off after Windows or system updates.
Turning on LSA that is manually turned off is easy, provided you know how to do it. On the other hand, if the process is closed by the system and it is done after every update, you may require serious actions to fix the error.
Without this process, your PC may be vulnerable to interception and data theft. Hence, it is important to keep it ON.
But how? Well, that is what we will share with you in this post.
Ensure you read this until the end, as we will explain how to enable Local Security Authority Protection on your PC. Using these steps, you can enable it even when the system cannot do so.
Local Security Authority Protection Off Warning on Windows – Why Does it Occur?
If that yellow exclamation mark in your security settings has appeared recently, chances are that the LSA process was affected by the recent turn of events on your PC.
Usually, the user turns off the Local Security Authority protection from the Task Manager as it appears to be a heavy process. However, if it is not manually disabled and is not running, there can be three reasons behind it –
- A corrupt Windows Update was installed on your PC, which caused the LSA to go off.
- The Secure Boot settings have been accidentally reset on Windows. It is the basic security feature that, when disabled, affects other programs, including LSA.
- Due to unnecessary changes in Group Policy Editor, LSA is disabled.
These 3 are the most probable causes of Local Security Authority Protection not running on your Windows PC. As you can realize, all of these require a power user to understand and move ahead to fix.

The Local Group Policy Editor is another way you can spot the LSA protection settings and enable them. Simply follow the steps given below –
Step 1 – Press Windows+R on your keyboard to open the Run Search.
Step 2 – In the Run Search, use the command “GPEDIT.msc.”

Step 4 – Following the above path, you can find the configured LSASS to run as a protected process.
Step 5 – Select the option mentioned above and right-click on it. You will find the enable option. Just click on it and restart your PC for changes to take effect.
Way #3 – Use Registry Editor to Enable LSA
In many Windows 11 PCs, the group policy editor is unavailable if you have never used it. If the above method did not work, you can use the registry editor to sort your Local Security Authority Protection off situation.
Here’s what you can do –
Step 1 – Press Windows + R to open the run search.
Step 2 – In the run search, use the command “regedit.”
Step 3 – This will open the registry editor for you.
Step 4 – In the registry editor, navigate to the following path –
Step 5 – Find RunAsPPL and RunAsPPL boot entries at the destination. If these are unavailable, create new DWORD entries with value 2 for both.
Once you have both the values set to 2, restart your PC, and you should be ready.
In case this does not work, there are chances that your registries require optimization. It is better to use Advanced System Optimizer in such situations instead of making unnecessary changes that may worsen the situation.
