Hi, and thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.

I understand the issue you have, nothing to worry I am here to help, This is happening when there is a corrupted file on the Windows Defender folder or a reconfiguration is needed, First, you need to check if you have a work or school account:

Open Settings> Click Accounts> Click Access work or school then disconnect the account there, if no account or already disconnected and you have the same issue follow the steps below:

Method 1. Repair Windows apps and Windows Defender:

On Powershell(admin), copy and paste the command below and hit enter:

Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

restart the PC and check

Method 2. Reinstall Windows Defender

Open the registry, then go to

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

Then delete the Windows Defender folder, restart the PC, and recheck it.

If none will work from the above solution, I suggest doing an in-place upgrade wherein it will upgrade the device to the latest version and repair all issues without deleting any files.

Note: before doing this make sure to create a restore point: https://support.microsoft.com/en-hk/help/402753...
