Sometimes you are required to open a single setting in Windows Security to run a particular program or disable a feature. When that is done you may get an error – You’ll need a new app to open this windowsdefender link.
You may think that a new Microsoft Store app is required to open a link in Windows Defender or Security. But the message is flawed. It gives a wrong indication that you need a new Store app. To fix this error you need to run a few Powershell commands. Powershell comes pre-installed with the Pro version or you need to install it if it doesn’t exist.
