Windows Security history is missing or not showing up in Windows 11

windows defender history record

Are you worried that your lost Windows Defender history hides infections? Windows Security's protection history tracks defenders' behavior to help you easily identify and remove threats. But what if your Windows security history is empty, missing, or not showing up? In this article, we'll look at the possible causes and the steps you can take to correct the problem.

Why is Windows protection history missing?

If you haven't cleared your Windows Defender protection history recently but it still appears blank, the reasons may be:

  • History settings not enabled: If you disable history settings, Microsoft Defender is not properly configured to log activities such as scans, detections, and other associated security-related events, which can cause problems.
  • Security Database Corruption: Microsoft Defender's security database maintains a record of all tasks performed by this application. Therefore, a corrupted security database prevents the system from logging and displaying details of previous events, resulting in a missing or blank protection history.
  • Problems with Windows Defender application: Corrupted application files, conflicts with third-party applications, or incorrect settings in the Defender application may be the reason for its incorrect operation. This may also result in security-related events for said application not being properly logged.
  • Fix the issue where Windows protection history is empty, missing, or not displayed

    If your Windows security history is empty, missing, or not showing up in Windows 11, here's how to fix it:

  • Delete Defender history files
  • Reset the Microsoft Defender application.
  • Run the DISM tool.
  • Check third-party software conflicts
  • For most solutions you may need to obtain permission from Amdin

    1]Delete Defender history file

    This problem can be effectively solved by cleaning the Defender history files by deleting any old files that may be corrupted or causing conflicts.

    • Open Windows Terminal by typing cmd on the desktop search bar.
    • Right click on it and select Run as administrator
    • On the terminal prompt type,
    Del“C:ProgramDataMicrosoftWindows Defenderscansmpcache*”/S>nul 2>&1
    <img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/164/170910709136225.jpg" class="lazy" alt="Windows 11中缺少或未显示Windows安全保护历史记录">
    Copy after login

    DEL: Delete command to delete files.

    "C:ProgramDataMICROSOFTWindows DefenderSCANSMPCACHE*: Indicates a delete command scan directory for erasing files starting with MPCACHE under...

    The

    /S flag helps the delete command execute recursively, not only deleting files in the specified directory, but also deleting files in its subdirectories.

    NUL plays a role in the command line similar to the pipe symbol | in PowerShell, used to redirect the output of the del command. By using NUL, you can ensure that no output messages are displayed on the terminal, such as confirmation messages when files are deleted.

    2>&1: Used to suppress the display of any error messages encountered during the deletion process.

    • After entering the above command type,
    Del“C:ProgramDataMicrosoftWindows DefenderScansHistoryServiceDetectionHistory*”
    Copy after login

    After that,

    Del“C:ProgramDataMicrosoftWindows Defenderscansmpenginedb.db”
    Copy after login

    After the removal process is complete, restart the system and check for errors.

    (2)Reset Windows Defender application

    Resetting Windows Security will restore the app to its default settings, which can help fix issues that have been preventing it from running. To reset,

    From [Start] Menu

    • Press the Windows I key to open the settings options.
    • Click Application Settings.
    • Look for Windows Security under the list of installed applications.
    • Once found, scroll down to find the reset option.
    • Click the reset button to reset the application.

    Windows 11中缺少或未显示Windows安全保护历史记录

    From Windows PowerShell

    • Type Windows PowerShell in the desktop search bar.
    • Click to run as administrator.
    • Enter the below mentioned command on the terminal prompt:
    Get-AppxPackage Microsoft.SecHealthUI-所有用户|Reset-AppxPackage
    Copy after login

    Windows 11中缺少或未显示Windows安全保护历史记录

    explain:

    Get-AppxPackage: Used to retrieve information about the installed Appx package. AppX happens to be the app packaging format used by Microsoft for Microsoft App Store apps.

    Microsoft.SecHealthUI: is the full name of Microsoft security package.

    -AllUsers: Option is used to specify the package information to be retrieved for all users in the system.

    |(pipeline): Helps pass the output of Get-AppxPackage to the command on the right side of the pipe.

    Reset-AppxPackage: Reset related packages for all users in the system.

    In summary, this command retrieves the Microsoftinformation.SecHealthUI package and resets or reinstalls the package.

    • 执行完上述命令后,重新启动系统。
    • 重新启动后,再次以管理员身份打开PowerShell。
    • 在终端提示符下输入以下命令:
    Add-Appx软件包-注册-DisableDevelopmentMode“C:WindowsSystemAppsMicrosoft.Windows.SecHealthUI_cw5n1h2txyewyAppXManifest.xml”
    Copy after login

    Windows 11中缺少或未显示Windows安全保护历史记录

    解释:

    Add-AppxPackage:在系统上添加或安装APPX包。

    -注册:应用程序安装后进行注册。注册过程包括将有关该程序包的信息添加到Windows应用程序存储库并使其可用。

    -DisableDevelopments模式:关闭开发模式;开发模式允许用户打开带有调试和部署选项的应用程序,这种情况下不需要。

    “C:WindowsSystemAppsMicrosoft.Windows.SecHealthUI_cw5n1h2txyewyAppXManifest.xml”:提到了AppXManifest.xml文件的路径,该文件包含应用程序的元数据和配置信息,如应用程序的描述和显示名称。

    总而言之,该命令在修复或重新安装后注册Microsoft.SecHealthUI和appx程序包。

    执行完上述命令后,重新启动系统,检查是否出现错误。

    3]运行DISM工具

    损坏的系统映像也可能导致保护历史记录丢失。在这种情况下,运行DISM工具可以帮助解决问题。

    4]检查第三方软件冲突

    第三方应用程序有时可能会与Microsoft Defender应用程序发生冲突并限制其功能,因此可能不会显示保护历史记录。在这种情况下,在干净启动状态下对问题进行故障排除也有助于解决错误。
