Windows Defender is the built-in antivirus protection in Windows 10. The Windows Defender helps protects your Windows 10 PC against viruses, spyware, malware, and other common threats.
Not all Windows 10 users are relaying on the built-in protection. A significant number of users have been using third-party antivirus programs like AVG Antivirus, Avira Antivirus, McAfee Free Antivirus, Kaspersky Antivirus, Avast Antivirus to protect their PC. That said, there are users who believe that the built-in protection is adequate to protect their data.
If you’re using Windows Defender in Windows 10, you might want to download the newly released Windows Defender Hub app from Microsoft.
Windows Defender Hub for Windows 10
The Windows Defender Hub app for Windows 10 doesn’t add any new capabilities to Windows Defender but it allows you quickly launch Windows Defender window (you can anyways do that by clicking Windows Defender icon in system tray) and displays news and updates about Windows Defender, malware and viruses.
The Windows Defender Hub is useful to check the status of Windows Defender on your PC.
Overall, a not so useful app for Windows 10 considering that you can subscribe to security articles from Microsoft, and check the status of Windows Defender by clicking its icon in the system tray. I would say that Windows Defender Hub is nothing but a Windows Defender launcher.
Visit the Windows Defender Hub page of Windows Store to download and install Windows Defender Hub app.
