I have trouble connecting to university wifi and it state "needed action". So I tried to reset my laptop and choose option keep my files only. When the process done, I tried to connect to the university wifi but the same problem occur. When I tried to open the windows security it only shows blank page. Furthermore, I remember that when i buy this laptop it only has 5GB usable for RAM, but after the reset it state that 13GB RAM usable. I think some files is missing but I dont know which one. I hope anyone can tell me whats wrong and what is missing when i do the reset and what I need to do to fix this problem. Thank you.

    Hello

    Thank you for posting in Q&A forum.

    Here are some additional steps you can try:

    1. Check Security Center Service

    • Press Win + R, type services.msc, and press Enter.

    • Locate Security Center in the list.

    • Ensure the Startup type is set to Automatic and the service is running. If it's not, right-click and select Start.

    1. Modify Registry Settings

    • Press Win + R, type regedit, and press Enter.

    • Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SecurityHealthService. • Ensure the Start value is set to 2 (Automatic). If it's set to 4 (Disabled), change it to 2.

    Note: please back up the registry before you make any change about it.

    1. Re-register Windows Security App

    • Open Windows Terminal (Admin) by pressing Win + X and selecting it.

    • Run the following command: Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage

    • Restart your computer.

    1. Run System File Checker and DISM

    • Open Command Prompt (Admin) by pressing Win + X and selecting it.

    • Run these commands one by one: sfc /scannow DISM /Online /Cleanup-Image /RestoreHealth

    • Restart your computer after each command.

    I hope the information above is helpful.

    If you have any questions or concerns, please feel free to let us know.

    Best Regards,

    Daisy Zhou
