Windows Defender Security Center: What It Is and How to Use It

Stand strong against malware and malicious attacks

Windows 10 computers come with a security feature called Windows Defender Security Center, which offers protection against viruses, spyware, and malware. 

Let's take a look at what the Center has to offer, how to access it, and go over a few of its key features.

What is the Windows Defender Security Center?

Your computer's primary line of defense against malware and viruses is the Windows Defender Security Center.

Once you install third-party antivirus software, the Center becomes secondary. Many antivirus features become inactive, but you can monitor your device's security from the Center's dashboard. Other security settings, such as those related to Microsoft Edge, parental controls, and your Microsoft account's protection, can also be adjusted from within the Center.

Antivirus Programs vs. Windows Security Center

There are a few differences between the Windows Defender Security Center and third-party antivirus programs. The first is the Center doesn't require installation or a paid subscription to access its services, since the Center already comes pre-installed on Windows 10 devices.

Second, since Windows Defender Security Center is the in-house antivirus and security program for Windows 10, its security features are specifically designed for the OS.

Additionally, Windows Defender Security Center doesn't put security services or premium security features behind a paywall. Windows 10 users have access to all of the Center's features provided their devices are updated and have the hardware to support its tools.

The Center's Dynamic lock settings allow you to pair a mobile device with your PC via Bluetooth so you can lock your PC when you step away from it. Secure Boot is a security feature that prevents a type of malware called a "rootkit" from accessing your device upon startup. Rootkits can usually slide into devices undetected and record your passwords and keystrokes, grab cryptographic data, and more.

Access the Security Center on Windows 10 Using Search

There are two ways to access the Windows Defender Security Center: searching for it using the desktop's Search box or selecting the Security Center icon in the desktop's System Tray menu.

  1. Select the Search box.

  2. Type "Windows Defender Security Center."

Use Windows Security Center to View Your Computer's Health Report

Regardless of whether you already have another antivirus security program running on your PC, the Center will still run a health scan of your computer to ensure everything's running smoothly. If not, the Health report feature will notify you. Here's how to access it.

  1. Access Windows Defender Security Center using one of the two methods described above.

  2. From the Center's dashboard, you can access the Health report in two ways:

    • Select Device performance & health.
    • Select the three horizontal lines on the dashboard's left side, then select Device performance and health.
