When I try to access my protection history Inside Windows Security, there are four blue dots that load forever. I've tried everything. Can I please get some help here? Thank you

Have you tried the batch file in the link TaoLi posted? Link: https://learn.microsoft.com/en-us/answers/questions/3922062/windows-10-checking-windows-securitys-protection-h

After running it, restart Windows.

Hello,

That message means the DetectionHistory folder has already been removed, so you do not need to run that command again.

Please open PowerShell as Administrator and run:

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

After it finishes, restart the PC and check Protection History again.

Microsoft also provides general app repair/reset guidance here: https://support.microsoft.com/en-us/windows/apps/repair-apps-and-programs-in-windows

If it still keeps loading, please let me know what happens after running the PowerShell command.

Hello,

This is usually caused by corrupted Windows Defender Protection History data.

Please boot Windows into Safe Mode, then open Command Prompt as administrator and run:

rd /s /q "C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service\DetectionHistory"

Restart the computer normally afterward and check Protection History again. This clears the existing Protection History entries but does not disable Microsoft Defender.
