Windows Defender, now known as Microsoft Defender Antivirus, is a powerful built-in security tool for Windows operating systems. While many users rely on its basic functionality to protect their PCs from malware, it also includes a variety of advanced features that can significantly enhance your system’s security. Here are three ways to unlock Windows Defender’s hidden features and maximize your PC’s protection.
1. Leverage Advanced Threat Protection (ATP)

How to Enable ATP:
- Open Windows Security by searching for it in the Start menu.
- Navigate to Virus & Threat Protection > Manage Settings under “Virus & Threat Protection Settings.”
- Scroll down and enable Cloud-Delivered Protection and Automatic Sample Submission.
- For enterprise users, ATP can be activated through Microsoft 365 Defender Portal for centralized threat management.
Why It’s Important:
- ATP uses real-time cloud intelligence to detect emerging threats faster than traditional antivirus software.
- It monitors unusual behavior on your system to flag potential risks before they escalate.
2. Utilize the Controlled Folder Access Feature
Controlled Folder Access is a hidden gem in Windows Defender that protects critical files from unauthorized changes, especially by ransomware. It prevents untrusted applications from accessing or modifying files in designated folders.

3. Perform a Boot-Time Scan
A boot-time scan is an advanced feature in Windows Defender that runs a deep system check before your operating system loads. This allows it to detect and remove deeply embedded malware that might evade regular scans.
How to Perform a Boot-Time Scan:
- Open Windows Security and navigate to Virus & Threat Protection.
- Under Current Threats, click Scan Options.
- Select Microsoft Defender Offline Scan and click Scan Now.
