The LSA warning is usually not something to worry about, since it is often just a warning. In fact, the Local Security Authority Protection is turned on by default in the newer versions of Windows 11. Local Security Authority Protection is a process within Windows that verifies a user’s identity, i.e., determining whether the user’s credentials are correct or not on platforms like Microsoft and Azure. LSA requires virtualization to work, and you should have virtualization enabled in the BIOS settings for it to function properly. There are various methods of enabling LSA on your computer. In this article, we will guide you through the different alternatives to the Windows Settings app for enabling LSA, as well as show you how to resolve the issue.
1. Enable LSA through the Windows Registry.
The first way you can enable LSA is through the Windows Registry app. Using the Windows Registry can be slightly intimidating since it controls the overall behavior of the operating system. Therefore, any unwanted change in the Windows Registry can cause various issues. If you are not tech-savvy, we would recommend enabling LSA via the policy editor window, as shown in the next method below. Before making any changes to the Windows Registry, we advise creating a backup of the Windows Registry to protect against any unfortunate events. Once you have done that, follow the instructions below to enable LSA:
2. Enable LSA through the Local Group Policy Editor.
Another method you can use is to enable the LSA using the Local Group Policy Editor. The Local Group Policy Editor is a Windows application that can be used to edit and manage the various policies on your computer. This is often used to configure advanced system settings that are not listed in the Settings app or the Control Panel. To enable LSA via the Local Group Policy Editor, follow the instructions below: Note: The Local Group Policy Editor is not enabled by default in Windows 10/11 Home Editions. Therefore, you must enable the Group Policy Editor in the Home Edition to continue with this method. Otherwise, you may skip this method.
3. Repair Windows Apps and Windows Defender
In some scenarios, the problem in question may be associated with a problematic Windows Defender on your computer, which is one of the main components of Windows Security. This can occur due to an inconsistency within Windows Defender or damaged app files. In such a scenario, you will need to repair Windows Defender and Windows apps to resolve the issue. To do this, follow the instructions below:
4. Manually update the Windows Security app.
The LSA Protection option was not available to toggle in the older versions of the Windows Security app due to a security bug. Microsoft has released an update to the Windows Settings app, which you can download and install to resolve this issue. In order to download and install the update, follow these steps:
5. Enable virtualization in the BIOS.
Finally, if none of the above methods have resolved the issue for you, it is likely that the issue is caused by the BIOS configuration on your computer. This is because LSA is an advanced security feature that requires CPU virtualization to work. As such, if virtualization is disabled on your computer, you will not be able to enable the feature. Thus, you will need to turn on virtualization from your BIOS settings to use the LSA feature on your system. CPU virtualization is essentially a feature of Intel and AMD processors that allows a single processor or core to function as multiple individual processors. This enables the operating system to utilize the power of your CPU more efficiently and can even result in your PC running faster. Depending on the manufacturer of your motherboard, the exact steps for enabling CPU virtualization may vary. Boot into your BIOS settings and navigate to the Advanced tab. You can often find the Virtualization option under the CPU Configuration section.
