10 Windows 11 security settings to keep your PC safe

Windows operating systems are renowned for their flexibility, allowing users to run applications from various sources. However, this openness can expose systems to potential security and privacy risks. Fortunately, Windows 11 offers a suite of built-in security features designed to protect users from malicious activities. While many of these settings are enabled by default, some users may inadvertently disable them, leaving their systems vulnerable. Below is a curated list of essential Windows 11 settings that should be activated to enhance your computer’s security.

10 Microsoft Defender

Built-in antivirus

Microsoft Defender, included with Windows 10 and 11, is a robust security program that actively protects your system against threats. When enabled, its real-time protection feature continuously scans for suspicious applications and files, quarantining any potential threats immediately. Consistently ranked among the top antivirus solutions by testing agencies, Defender’s deep integration with Windows ensures seamless compatibility and regular updates through Windows security patches.

To activate the real-time scan, simply search for Windows Security and enable the Virus and Threat Protection option. You can also perform a comprehensive system scan using options like Quick Scan, Full Scan, Custom Scan, or Offline Scan.

9 Firewall & network protection

Built-in defense

The Firewall and network protection feature in Windows acts as a gatekeeper, monitoring incoming and outgoing traffic to prevent unauthorized access. By blocking suspicious connections, it safeguards your data from potential threats. This feature is enabled by default on Windows 11, but users can customize inbound and outbound rules for specific applications to enhance security further.

To verify that the Firewall is active, navigate to Windows Security and check the Firewall & network protection section, ensuring it is turned on for all network types: Public, Private, and Domain.

8 App & browser control

Site screening for safety

App & browser control is a vital feature that protects your system from harmful applications, files, and websites. Utilizing the SmartScreen feature, it checks URLs and downloads against a regularly updated database of known threats. This proactive measure blocks installations from untrusted sources, preventing accidental or hidden installations of malicious software.

To enable features like SmartScreen for Microsoft and Phishing Protection, navigate to Windows Security > App & browser control settings.

7 Core isolation

Protection for the most sensitive

Core isolation, part of Windows Device Security, adds an extra layer of protection through features like Memory integrity and Memory access protection. These functionalities leverage virtualization-based security to safeguard sensitive processes and prevent cyber attackers from injecting malicious code into high-security areas of your system.

Users can enable these features by accessing the Device Security section within Windows Security and selecting Core isolation details.

6 Ransomware protection

Don’t get lost in their web

Ransomware attacks pose significant threats, and Windows 11 includes a dedicated Ransomware protection feature to shield your files and folders from encryption by malicious software. This feature allows you to safeguard important folders from unauthorized access and provides recovery options in the event of an attack.

To enable ransomware protection, go to Windows Security and activate Controlled folder access. You can add specific folders to the protection list for enhanced security.

5 BitLocker Encryption

Only available on some Windows 11 versions

BitLocker is a powerful encryption tool that secures your hard disk data, making it nearly impossible for unauthorized users to access encrypted information, even if the device is stolen. This feature is available only on Windows 11 Pro, Enterprise, and Education editions.

To enable BitLocker on a drive, right-click on the drive and select Turn on BitLocker, or search for “BitLocker” in the search box and access the settings.

4 Secure Boot

BIOS level protection

Secure Boot is a BIOS-level setting that ensures Windows boots only with trusted software from the manufacturer, preventing malicious actors from hijacking the boot process. This feature is a requirement for installing Windows 11 and works in tandem with BitLocker to protect drive data.

To enable Secure Boot, access the BIOS settings before booting Windows and locate the Secure Boot option.

3 Dynamic Lock

Automatic lock-down

For those who work in public spaces, Windows Dynamic Lock offers a convenient way to secure your device. By pairing your laptop with a Bluetooth-enabled device, such as a smartphone, the laptop will automatically lock when the paired device goes out of range, preventing unauthorized access.

To enable Dynamic Lock, navigate to Settings under Sign-in options and pair your laptop with your smartphone via Bluetooth.

2 Windows Hello

Biometric authentication

Windows Hello introduces an advanced biometric security feature that allows users to log in using facial recognition, fingerprints, or a PIN. This method not only streamlines the login process but also enhances security, making it difficult for unauthorized users to gain access.

To enable Windows Hello, go to Accounts > Sign-in options or search for the options directly. Ensure your device is equipped with the necessary hardware for biometric authentication.

1 User Account Control (UAC)

Admin authorization required

User Account Control (UAC) is a crucial security feature that prompts users for confirmation whenever an action requiring administrator-level permission is initiated. This mechanism helps prevent unauthorized changes and accidental installations of suspicious applications.

Users can adjust the UAC notification levels from Never Notify to Always Notify, with the latter recommended for maximum security.
