3. 使用 DISM^{(Use DISM)}修复损坏的Windows Update系统文件
4. ^{(Install Windows Update)}在干净启动状态下^{(Clean Boot State)}安装 Windows 更新。

依次尝试以下解决方案来解决问题：

1]运行^(Run)Windows更新^{(Windows Updates Troubleshooter)}疑难解答

Windows 更新疑难解答^{(Windows Updates Troubleshooter)}是一个出色的工具，可以检查Windows 更新^{(Windows Updates)}、相关服务的异常情况，并修复不兼容的更新。运行Windows 更新疑难解答^{(Windows Updates Troubleshooter)}的过程如下：

单击开始^(Start)并转到Settings > Updates & Security > Troubleshoot。

从列表中选择Windows 更新疑难解答^{(Windows Updates Troubleshooter)}并运行它。

该过程完成后重新启动系统。

您还可以运行Windows 更新在线疑难解答^{(the Windows Update Online Troubleshooter)}。

2]检查^(Check)以下Windows 服务的状态^(Services)

打开Windows 服务管理器^{(Windows Services Manager)}并检查与Windows 更新^{(Windows Update)}相关的服务，如Windows Update、Windows Update Medic、Update Orchestrator服务等是否被禁用。

独立 Windows 10 PC 上的默认配置如下：

• Windows 更新服务 - 手动^{(Windows Update Service – Manual)}（触发^(Triggered)）
• Windows更新医疗^{(Update Medic)} 服务^(Services) - 手册^{(– Manual)}
• 加密服务 - 自动

要修复损坏的 Windows Update 系统文件，请键入以下命令，然后按Enter 键^(Enter)运行DISM^{(Run DISM)}：

DISM.exe /Online /Cleanup-image /Restorehealth

请^(Please)注意，在这里您需要耐心等待，因为该过程可能需要几分钟才能完成。

当您运行上述命令时，DISM将用好的文件替换可能损坏或丢失的系统文件。

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。

4]在干净启动状态下^{(Clean Boot State)}安装Windows Update^{(Install Windows Update)}

如果第三方软件干扰了Windows 更新^{(Windows Update)}进程，从而导致讨论中的错误，您可以尝试在干净启动状态^{(Clean Boot State)}下重新启动系统后安装Windows 更新^{(Windows Updates)}。在这种状态下，所有第三方程序在启动时都保持禁用状态。

如果它有效，那么你的问题暂时解决了，对于未来，你可以通过点击和试用来调查这个麻烦的程序并将其删除，除非它很重要。

如果上述解决方案无法正常工作，您可能需要在系统上执行修复安装或全新安装。相反，许多用户最终在全新安装后解决了这个问题。

Fix Windows Update error 0x8007043c

It would be a very irritating situation if Windows Updates throws uр error codе 0x8007043c. This error usually occurs if any Windows Service that is required by Windows Update runs into problems. It may occur if you try to run the Windows Update Standalone Installer in Safe Mode or if you run Windows Update in the regular mode too. In case you encounter this issue, check this article for its troubleshooting.

Windows Update error 0x8007043c

There are many possible causes behind this issue but one thing we know is that this error has been around for more than a decade with no fix. The most probable causes of error 0x8007043c are an overprotective third-party, system file corruption, or an incompatible update.

1. Run the Windows Updates Troubleshooter
2. Check the status of the following Windows Services
3. Use DISM to fix corrupted Windows Update system files
4. Install Windows Update in Clean Boot State.

Try the following solutions sequentially to troubleshoot the problem:

1] Run the Windows Updates Troubleshooter

The Windows Updates Troubleshooter is an excellent tool to check for irregularities with Windows Updates, the associated services, and fixes an incompatible update. The procedure to run the Windows Updates Troubleshooter is as follows:

Click on Start and go to Settings > Updates & Security > Troubleshoot.

Select the Windows Updates Troubleshooter from the list and run it.

Restart the system once the process has completed.

You could also run the Windows Update Online Troubleshooter.

2] Check the status of the following Windows Services

Open Windows Services Manager and check the Windows Update related Services like Windows Update, Windows Update Medic, Update Orchestrator Services, etc are not disabled.

The default configuration on a standalone Windows 10 PC is as follows:

• Windows Update Service – Manual (Triggered)
• Windows Update Medic Services – Manual
• Cryptographic Services – Automatic
• Background Intelligent Transfer Service – Manual
• Windows Installer – Manual.

This will ensure that the required Services are available.

3]  Use DISM to fix corrupted Windows Update system files

To fix corrupted Windows Update system files, type the following command, and then press Enter to Run DISM:

DISM.exe /Online /Cleanup-image /Restorehealth

Please note that here you need to be patient since the process can take up to several minutes to complete.

When you run the command mentioned above, DISM will replace potentially corrupted or missing system files with good ones.

However, if your Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files.

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.

Once the process is complete, DISM will create a log file in %windir%/Logs/CBS/CBS.log and capture any issues that the tool finds or fixes.

Close the command prompt, and then run Windows Update again and see it has helped.

4] Install Windows Update in Clean Boot State

In case a third-party software is interfering with the Windows Update process, thus causing the error in the discussion, you could try installing the Windows Updates after restarting the system in Clean Boot State. In this state, all third-party programs remain disabled at startup.

If it works, your problem is solved for the time being, and for the future, you could investigate the troublesome program by hit and trial and remove it unless it’s important.

If the above-mentioned solutions fail to work, you might need to perform a repair install or clean install on your system. Rather, many users eventually resolved this issue after a clean install.
