If you are encountering the error “You’ll need a new app to open this windowsdefender link” while trying to access the Windows Security Center, it is a prevalent issue that affects users, especially after updates or when there’s interference from third-party antivirus software. This tutorial will guide you through the necessary steps to resolve this windows security center issue on both Windows 10 and Windows 11 systems.
Before proceeding with more complex solutions, perform the following preliminary steps:
Restart Your Computer: Sometimes, a simple restart can resolve the issue.
Close All Applications: Ensure that no applications are running in the background.
Access PowerShell:
Click on the Start menu.
Start typing “PowerShell.”
When “Windows PowerShell” appears in the search results, right-click it and select Run as Administrator.
Follow these steps carefully to troubleshoot the “You’ll need a new app to open this windowsdefender link” error on Windows 11:
In the PowerShell prompt, type the following command and press Enter:
Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage
Wait for the command to complete.
Exit PowerShell and restart your computer.
Relaunch PowerShell as an administrator.
Change the execution policy to unrestricted by typing:
Set-ExecutionPolicy Unrestricted
Reinstall all system applications without enabling development mode:
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
Revert the execution policy to restricted:
Set-ExecutionPolicy Restricted
Ignore any errors that appear during this process.
If you’re using Windows 10, the steps to resolve the windows security center issue are slightly different:
Launch PowerShell as Administrator.
Type and execute:
Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage
If the problem persists, try registering the Windows Security app manually:
Add-AppxPackage -Register -DisableDevelopmentMode “C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy\AppXManifest.xml”
Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage
Following these steps should resolve the “You’ll need a new app to open this windowsdefender link” error and restore access to the Windows Security Center. If issues continue, it may be necessary to consult Microsoft support or consider a system restore as a last resort. Remember, maintaining your system with regular updates and trusted antivirus solutions is key to preventing such issues.
