Go to the SATA configuration section in order to edit it to Combination mode (AHCI, SATA).

Next, navigate to VGA settings and change the video settings from PEG to PCI.

Save the changes and continue with the boot-up process. Now the missing or corrupt @system32driverspci.sys error should be gone.

To name a few features, the streamlined new design includes pastel-like colors and rounded corners, a redesigned Start menu, and larger touch targets for a better PC tablet interface.

As a result of the support for Android apps through the Amazon Store, as well as a new way to see your interests at a glance thanks to the Widgets feature, upgrading to the new operating system is clearly a compelling proposition.

It is important to note that the Local Security Policy may be missing in some older Windows versions, particularly the Home editions. If this is the case, we show you different ways to add it to your Windows 11 in this article.

Does Windows 11 have security protection?

The Windows operating system has always been a target for hackers. Windows 11, however, has been designed to be more secure than ever before. The operating system offers several security features to prevent malware from spreading and protect users from attacks.

To start, Windows 11 has a built-in antivirus and antimalware software called Windows Defender. However, there are some other security features that you can use to help protect your PC.

For instance, Windows Hello is a facial recognition feature that lets you log in using just your face instead of typing in a password or PIN every time you want to use your computer. 

We also have an in-depth comparison of Windows Hello vs Windows Hello for Business, so be sure to check that out. This feature works with many devices, including PCs and laptops, tablets, smartphones, and desktops. 

Whereas these features may enhance your Windows security, you need to take additional steps to secure your system.

These include:

Use a good antivirus program – Although Windows Security offers great security, it is not as comprehensive as other antiviruses.

Install Windows updates as soon as they are available – Security updates are critical to the smooth running of your PC. 

Set up a firewall to block incoming traffic from unknown sources – Firewalls will help block any potential risks from a mile away.

Don’t connect to public Wi-Fi networks unless you really need to – Public Wi-Fi is a no-go zone for any internet user, as cyber attackers are always lurking.

Keep your software up-to-date at all times – Ensure that all your programs and drivers are up-to-date so that if an opportunity to explore vulnerabilities presented itself, you’ll be protected.

How do I add a Local Security Policy in Windows 11?

Expert tip:

To do so:

Hit the Windows + R keys to open the Run command.

Type Winver in the dialog box, then hit Enter. A prompt will appear with details about your OS.

Once you verify that your version of Windows can download the Local Security Policy console, proceed to the following steps to add it.

1. Use Task Manager  2. Use File Explorer 

Hit the Windows + E keys to open File Explorer.

Type chúng tôi on the address bar and hit Enter.

The Local Security Policy window will open.

3. Use the Run command

Hit the Windows + R keys to open the Run command.

Type chúng tôi in the dialog box and hit Enter.

The Local Security Policy window will open.

4. Use the Command Prompt 5. Use Powershell  6. Create a shortcut

If you’re already familiar with creating shortcuts in Windows 11, creating a shortcut for the Local Security Policy should be easy. Shortcuts are very useful for making your life easier and more efficient. 

Creating a shortcut is the most efficient way to add the Local Security Policy, especially if you don’t want to go through multiple steps.

Consequently, when you search for the Local Security Policy using the Search icon, you can pin it to your Taskbar. This will make it appear alongside your frequently used applications and be easy to locate.
