windows 安全性功能問題

孝寬 白 0 Reputation points

最近更新了Win11之後我的windows 安全性這項功能不能打開,查看之後想是一項功能叫「應用程式與瀏覽器控制」顯示驚嘆號,但我一直查不出原因,是要登入windows之後才能正常開啟嗎? 還是說不用登入也能正常開啟此項功能呢? 這是我第一次遇到的問題,以往都沒有遇到此項問題。

Recently after updating Win11, my windows security feature can't be opened, after checking it, I think it's a feature called “Application and Browser Control” showing exclamation mark, but I haven't been able to find out the reason, do I have to log in windows to open it properly? Do I have to log in to windows to open this function? Or can I open this function without logging in? This is the first time I've encountered this problem, I've never encountered it before.

    Here are some potential scenarios that might cause this behavior on Windows 11:

    1.Corrupted Windows Store Certification: A corrupted Windows Store certification can prevent access to Windows Security. Reinstalling the Microsoft.SecHealthUI component can resolve this.

    Open powershell window with admin access, paste the following command and press Enter to reset the Windows Store certification:

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

    After the command is run successfully, reboot your PC and see if the problem is fixed once the next startup is complete.

    2.Corrupted Windows Security Component: Upgrading to Windows 11 might leave some components partially corrupted, you may run the command suggested in  

    Windows Defender won't open? Here's how to fix it! (Windows 11) - Microsoft Community to fix it.

    3.Interference from 3rd Party Antivirus Suites: Some third-party antivirus software can block access to Windows Security. Disabling or uninstalling the conflicting antivirus software can fix the issue.

    4.System File Corruption: System file corruption affecting Windows Security or its dependencies can be an issue. Running an SFC and DISM scan can help.

    Another user has reported that you can download the Windows Security App from the Microsoft website, then you will be able to launch the Windows Security app.
