Fix – Unable to Open Windows Defender Settings in Windows 11 Latest Build

Microsoft recently rolled out Windows 11 build 22000.120 in Dev and Beta channel. It comes with lots of new features and bug fixes. Some users reporting that after installing the same build Windows Defender is broken.

What actually happening is, when users launch Windows Security app on Windows 11 PC, a quick dialog box appears “You’ll need a new app to open this Windows Defender link” accompanied by the option “Look for an app in Microsoft Store.“

Apart from that, other users reported that they’re seeing the same dialog box when trying to access various settings in Windows Defender.

FYI, Windows Defender is a security app that comes preinstalled in Windows 10 and Windows 11 too. It protects your device from malicious files.

From the day, Microsoft released its first build of Windows 11, users have been reporting about various bugs and issues related to Windows Defender. Although, most of them are fixed with the latest updates. The above-discussed issue is fresh and still active.

• Second, launch the Feedback app and report about it. So that Microsoft is aware about the issue and fix it
