Windows operating systems include a variety of built-in features designed to help protect your PC from malware, ransomware, and other security threats. However, many users overlook these features or fall into common traps that can leave their systems vulnerable. This article explores 15 essential built-in Windows features you should use (and avoid misusing), practical advice for leveraging them effectively, and real-world mistakes to avoid. Whether you’re a beginner or an advanced user, you’ll find actionable steps for improving your Windows privacy and security posture.
Why Do Malware Protection Strategies Fail?
Before diving into specific features, it’s important to understand common areas where security strategies fall short:
– Overconfidence in a single tool or default settings
– Neglecting to update Windows and security tools
– Disabling protections for convenience or performance
– Ignoring privacy settings
– Failing to recognize the importance of user behavior
By being aware of these pitfalls and using built-in Windows security features wisely, you can greatly reduce your risk.
Built-in Windows Features for Malware Protection: What Not to Miss
Here are 15 essential features you should be using, along with advice on avoiding common mistakes.
1. Windows Security (Windows Defender)
Don’t disable Windows Security. Many users turn it off after installing third-party antivirus tools, leaving a vulnerability window. Even with another antivirus, keep Windows Security running for layered protection. Regularly run manual scans for peace of mind.
2. Controlled Folder Access
This feature helps block ransomware by preventing unauthorized apps from altering your files. Avoid the mistake of ignoring this setting—enable it under Windows Security > Virus & threat protection > Ransomware protection. Add folders with sensitive data for extra protection.
3. SmartScreen Filter
Windows SmartScreen warns against phishing sites and malicious downloads. Don’t disable SmartScreen for the sake of convenience; doing so exposes you to web-based threats. Leave it enabled in Windows Security > App & browser control.
4. Automatic Updates
The most basic mistake is delaying or disabling Windows Updates. Always allow automatic updates for both Windows and Windows Defender definitions. Check Settings > Update & Security > Windows Update regularly and restart promptly after updates.
5. User Account Control (UAC)
Some advanced users lower or disable UAC prompts for fewer interruptions. This is dangerous. UAC prevents malware from making system-wide changes. Keep it to at least the default setting for essential protection.
6. Built-in Firewall
Never turn off the Windows Firewall, thinking a router or antivirus is enough. The firewall blocks unauthorized inbound and outbound traffic. Check its status in Control Panel > Windows Defender Firewall and ensure it’s always on for all networks.
7. Microsoft Edge Security Features
Edge includes anti-phishing, isolated browsing (Application Guard), and tracking prevention. Don’t ignore these—use Edge for risky sites and enable its security features under Settings > Privacy, search, and services.
8. BitLocker Drive Encryption
If you skip encryption, lost or stolen devices put your data at risk. Enable BitLocker on Windows Pro and higher (Settings > Update & Security > Device encryption or BitLocker settings). Don’t forget to back up recovery keys.
9. Windows Hello and Advanced Sign-in Options
Relying solely on passwords is risky. Use Windows Hello (face, fingerprint, or PIN) for stronger, faster authentication. Set up in Settings > Accounts > Sign-in options.
10. Secure Boot
Disabling Secure Boot for dual-booting or legacy software is a common pitfall. Secure Boot helps prevent rootkits by verifying boot integrity. Keep it on in your firmware (UEFI/BIOS) settings.
11. Application Guard
Advanced users should leverage Windows Defender Application Guard to isolate untrusted apps or browsers. This feature runs risky apps in virtualized containers, preventing malware from escaping to your main system.
12. Account Isolation and Limited User Accounts
Don’t run daily tasks as an administrator. Create a standard user account for everyday use, reserving admin rights for special tasks. This limits the damage malware can do if it runs under your profile.
13. Storage Sense and Disk Cleanup
Malware can lurk in unused files and downloads. Regularly use Storage Sense (Settings > System > Storage) to clear out old data. For deeper cleanup, use tools like Glary Utilities, which can automatically remove temporary files and system junk, reducing the risk of hidden malware.
14. Network Profiles and Sharing Settings
Using public networks with open sharing settings is dangerous. Set your network to Public in Settings > Network & Internet, and turn off file/printer sharing unless needed. Use the built-in Network troubleshooter to verify safe settings.
15. Privacy Dashboard and App Permissions
Many malware threats exploit unnecessary app permissions. In Settings > Privacy, review app permissions for microphone, camera, location, and background apps. Disable access for apps that don’t need them. It’s a simple way to reduce attack vectors.
Extra Tip: Use Glary Utilities for Routine Maintenance
In addition to Windows’ built-in tools, supplement your routine with Glary Utilities. It offers features like one-click maintenance, privacy cleaning, malware detection, and registry repair, all of which help remove potential threats and optimize your system for better security.
Advice for Beginners
– Always keep Windows and your security tools updated.
– Never disable built-in protections for convenience.
– Run manual scans with Windows Security and Glary Utilities.
– Use strong, unique passwords with Windows Hello.
– Be cautious with downloads and suspicious emails.
Advice for Advanced Users
– Audit your network and firewall rules regularly.
– Use Application Guard for testing suspicious files.
– Create separate virtual machines for risky software or browsing.
– Monitor system processes and startup apps with Task Manager and Glary Utilities’ Startup Manager.
– Regularly back up your system with File History or a third-party tool.
Conclusion: Strong Malware Protection is Layered and Ongoing
Windows provides a powerful set of built-in features against malware, but their effectiveness depends on how you use them. Avoid the common mistake of neglecting updates, disabling protections, or relying solely on one line of defense. Regularly review your settings, combine built-in features with trusted maintenance tools like Glary Utilities, and stay informed about new threats. Both beginners and advanced users can benefit from a proactive, layered approach—keeping your Windows PC safe, private, and running smoothly.
