Windows 11’s Updated Security Protocols: What’s Changed?

Windows 11 comes with a range of updated security protocols that aim to provide users with a more secure and protected computing environment. With the increasing importance of digital security and privacy, it is essential to understand the changes and enhancements made to Windows 11’s security features. In this guide, we will explore the updated security protocols in Windows 11 and highlight the key changes that have been implemented to safeguard your data and protect against potential threats.

One of the notable changes in Windows 11’s security protocols is the integration of Microsoft Defender Antivirus and advanced threat protection measures. Windows 11 provides enhanced protection against malware, ransomware, and other malicious threats through its built-in security solutions. Additionally, Windows Hello – Microsoft’s biometric authentication technology – has been improved to provide a more convenient and secure way to access your device. By understanding these updated security protocols in Windows 11, you can strengthen your overall security posture and ensure that your data and privacy are well-protected. Join us as we dive into the world of Windows 11’s updated security protocols and discover how these changes can enhance your digital security.

Step 1: Enable Windows Hello Facial Recognition or Fingerprint Authentication

Windows 11 offers improved biometric authentication options, allowing you to securely sign in to your system. Open the Settings app by clicking on the Start menu and selecting the gear icon. Go to “Accounts” and select “Sign-in options.” Set up Windows Hello by following the on-screen instructions to enable facial recognition or fingerprint authentication.

Step 2: Use TPM 2.0 for Enhanced Hardware Security

Windows 11 now requires a Trusted Platform Module (TPM) version 2.0 for increased hardware security. To check if your system has TPM 2.0, press the Windows key + R, type “tpm.msc,” and press Enter. The TPM management tool will open, and you can verify if TPM version 2.0 is present. If your device lacks TPM 2.0, consider upgrading your hardware or enabling it in your BIOS settings if supported by your device.

Step 3: Update to Windows 11’s Secure Boot

Windows 11’s Secure Boot feature helps prevent unauthorized operating systems and malware from loading during the system startup process. To enable Secure Boot, access your system’s UEFI or BIOS settings by restarting your computer and repeatedly pressing the respective key (usually displayed during boot). Once in the UEFI/BIOS settings, locate the Secure Boot option and follow the provided instructions to enable it.

Step 4: Activate Windows Defender Antivirus and Firewall

Windows 11 boasts built-in security features, such as Windows Defender Antivirus and Firewall, providing robust protection against malicious threats. Ensure these features are activated by opening the Settings app, clicking on “Privacy & Security,” and confirming that Windows Defender Antivirus and Firewall are enabled. You can also customize their settings to suit your security preferences.

Step 5: Enable Automatic Updates for Enhanced Security Patches

Keeping your operating system up to date is crucial for security. Windows 11 offers improved automatic updates to ensure you receive the latest security patches and enhancements promptly. Open the Settings app, click on “Windows Update,” and select “Advanced options.” Make sure the “Automatic (recommended)” option is enabled under the “Choose how updates are installed” section.

Step 6: Set Up Windows Sandbox for Secure Testing

Windows Sandbox allows you to run potentially risky applications in a secure, isolated environment. To enable Windows Sandbox, open the Settings app, click on “Apps,” and select “Windows Features.” Scroll down and enable Windows Sandbox from the list of features. Once enabled, you can open Windows Sandbox from the Start menu to safely test applications without compromising your system’s security.

Step 7: Utilize Microsoft Defender Application Guard (Enterprise Edition)

For enterprise users, Windows 11 introduces Microsoft Defender Application Guard, which provides additional security by running potentially unsafe apps and websites in a virtualized container. If you are an enterprise user, contact your IT department or refer to Microsoft’s documentation for proper setup and usage instructions.

Step 8: Regularly Back Up Your System and Files

Creating regular backups is essential to protect your data from potential security breaches or system failures. Windows 11 includes a built-in Backup & Restore feature that allows you to back up your files and system settings. Alternatively, consider using reliable third-party backup solutions to ensure comprehensive data protection.


Windows 11’s updated security protocols bring significant enhancements to safeguard your system from threats. By following these detailed step-by-step instructions, you can ensure your computer is well-protected and enjoy a more secure computing experience in the Windows 11 environment.
