如果在运行Windows 更新疑难解答后收到错误消息，某些安全设置在Windows 10上^{(Windows 10)}丢失或已更改^{(Some security settings are missing or have been changed)}，请参阅这些建议以了解如何解决它。如果您想知道 - 是什么导致“^{( “Your device is missing important security and quality fixes” )}您的设备缺少重要的安全和质量修复”消息出现？—那么，出现此消息的原因可能有很多。这可能是Windows 模块安装程序服务^{(Windows Modules Installer Service)}、损坏的 Windows^{(Corrupt Windows)}文件、磁盘^(Disk)空间等问题。

某些安全设置丢失或已更改

以下是您可以遵循以解决问题的建议列表。

1. 重新启动 Windows 模块安装程序服务^{(Restart Windows Modules Installer Service)}
2. 重新注册Windows 模块安装程序服务^{(Windows Modules Installer Service)}
3. 修复^(Repair)损坏的Windows 更新^{(Windows Update)}文件。

您将需要管理员权限才能执行它。

1]重新启动Windows模块安装程序服务^{(Restart Windows Modules Installer Service)}

• 右键单击^{(Right-click)}任务管理器^{(Task Manager)}，然后切换到服务^(Services)选项卡
• 找到 Trusedinstaller^{(Locate Trusedinstaller)}或Windows Installer Service，右键单击并启动。
• 如果它不起作用，请右键单击并选择Open Services。
• 再次找到^(Locate)该服务，然后禁用，然后启用它。

一旦服务启动并运行，它将确保如果问题是因此而解决的。

2]重新注册Windows模块安装服务^{(Windows Modules Installer Service)}

要修复Windows Modules Installer^{(Windows Modules Installer)}服务或 msiexec.exe的任何注册问题，请打开Run Prompt，然后键入CMD，使用Shift + Enter以管理员权限启动命令提示符。

%windir%\system32\msiexec.exe /unregister
%windir%\system32\msiexec.exe /regserver
%windir%\syswow64\msiexec.exe /unregister
%windir%\syswow64\msiexec.exe /regserver

如果您有 32 位系统，则应使用前两个命令。否则，您可以使用 64 位选项。完成后，您可以再次尝试更新。

3]修复损坏的Windows文件

您需要使用 DISM Tool 损坏 Windows Update 系统文件。

运行以下命令并查看：

DISM.exe /Online /Cleanup-image /Restorehealth

但是，如果您的 Windows 更新客户端已经损坏^{(Windows Update client is already broken)}，系统将提示您使用正在运行的Windows安装作为修复源，或使用网络共享中的Windows并行文件夹作为文件源。

然后，您将需要运行以下命令：

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess

在这里，您必须将 C:\RepairSource\Windows 占位符替换为修复源的位置。

该过程完成后，DISM将在^(DISM)%windir%/Logs/CBS/CBS.log中创建一个日志文件，  并捕获该工具发现或修复的任何问题。

关闭命令提示符，然后再次运行Windows Update并查看它是否有帮助。

You will then be required to run the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess

Here you have to replace the C:\RepairSource\Windows placeholder with the location of your repair source.
