You will need a new app to open this windowsdefender link

I have recently upgraded to Windows 11 which is now on the Beta Channel, the only unofficial problem i have is with Windows Security.

Here's What i get when i try to click on any Windows Security link

I tried all solutions on the official docs, articles, etc.., but nothing worked for me.

Note: commands like Get-AppxPackage to get a manual installation gave me an error when trying to execute them.

Version:

Windows 11 Pro Version 21H2 build 22000.132

Here's What I get when I try to click on any Windows Security link

The following command will fix Windows Defender:

Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage

There honestly wasn't anything special about the command I suggested. The problem described can happen on Windows 10. On Windows 10 it appears the package was instead called Microsoft.Windows.SecHealthUI. Performing a Reset on a UWP application is a normal operation, it's only more complicated, due to the fact Microsoft.Windows.SecHealthUI or Microsoft.SecHealthUI isn't your typical UWP package.

The "You'll need ..." message can happen file extension and performing a Reset on the appropriate UWP package will typically solve the problem.
