In an age where malware, ransomware, and phishing attacks are more sophisticated than ever, keeping your devices safe is non-negotiable. If you’re a Windows user, chances are you’ve already met your first line of defense — Windows Defender Security Center. This all-in-one security suite is built into Windows 10 and 11, offering a robust range of tools to keep your system secure.
In this comprehensive guide, we’ll explore what Windows Defender Security Center is, break down each of its key controls, and show you how to configure them to maximize your protection.
