Windows 更新错误 0x80096004

为了修复Windows 11/10上Windows 更新^{(Windows Update)}的错误 0x80096004 ，我们将执行以下修复，

• 替换 crypt32.dll 文件。

1]替换crypt32.dll文件

Crypt32.dll是在^{(Crypt32.dll)}CryptoAPI中实现许多证书^{(Certificate)}和加密消息^{(Cryptographic Messaging)}功能的模块

上面提到的文件位于此路径上-

对于 x86：

This PC > C:\Windows\System32.

对于 x64：

This PC > C:\Windows\SysWOW64.

从具有相同文件版本号的另一台计算机获取新文件。

然后，您需要 启动到安全模式^{(boot into Safe Mode)}，导航到上述路径，然后替换文件。

接下来，通过在 Cortana 搜索框中搜索 cmd 打开命令提示符^(Cortana)，并以管理员 级别 ^(cmd )权限^{(Command Prompt)}运行^{(Administrator)}它。

键入以下命令并按Enter键重新注册 dll 文件-

regsvr32 crypt32.dll

重启看看。

2]重置Windows Update^{(Reset Windows Update)}相关文件夹

您需要删除 SoftwareDistribution 文件夹^{(SoftwareDistribution folder)}的内容 并 重置 Catroot2 文件夹^{(reset the Catroot2 folder)}。

3]使用Windows更新疑难解答^{(Use Windows Update Troubleshooter)}

您可以运行 Windows 更新疑难解答 以及 Microsoft 的 在线 Windows 更新疑难解答^{(Online Windows Update Troubleshooter)} ，并检查这是否有助于解决您的任何问题。

4]配置^(Configure)防火墙^(Firewall)或防^(Antivirus)病毒

您可以尝试暂时 禁用^{(disable Windows Defender)} 在 Windows 10 计算机上开箱即用安装的 Windows Defender。您还可以 在计算机上禁用 Windows 防火墙^{(disable your Windows Firewall)} 并检查是否可以解决您遇到的错误。如果您使用的是第 3 方安全软件，请禁用它们并查看。

5]手动下载^(Download)所需的更新

如果不是功能更新，只是累积更新，您可以 手动下载并安装 Windows 更新^{(manually download and install the Windows Update)}。要查找未能按照以下步骤进行的更新：

• 转到Settings > Update和Security > View Update History
• 检查^(Check)哪个特定更新失败。安装失败的更新将在状态^(Status)列下显示失败。^(Failed)
• 接下来，转到 Microsoft 下载中心^{(Microsoft Download Center)}，并使用 KB 编号搜索该更新。
• 找到后，下载并手动安装。

6]使用系统文件检查器

以管理员身份打开命令提示符^{(Command Prompt as administrator)}并通过执行以下命令运行系统文件检查器：

sfc /scannow

扫描完成后重新启动系统。

您还可以使用我们的免费软件 FixWin通过单击 运行系统文件检查器^{(System File Checker)}实用程序。

7]在干净启动状态下^{(Clean Boot State)}运行Windows^{(Run Windows)}更新

干净启动^{(Clean Boot)}以最少的驱动程序和启动程序启动系统。当您以干净启动方式启动计算机时，计算机将使用预先选择的最少驱动程序和启动程序集启动，并且由于计算机以最少的驱动程序启动，因此某些程序可能无法按预期运行。

您可以在启动到干净启动状态后运行^{(Clean Boot State)}Windows 更新^{(Windows Update)}，并检查这是否会使错误消失。

All the best!

Today, we will be checking out how to fix error code 0x80096004 for Windows Updates on Windows 11/10.

Windows Update error  0x80096004

To fix the error 0x80096004 for Windows Update on Windows 11/10, we will be carrying out the following fixes,

• Replace the crypt32.dll file.
• Reset Windows Update folders.
• Use Windows Update Troubleshooter.
• Configure the Firewall or Antivirus.
• Download the required update manually.
• Use System File Checker.
• Run Windows Updates in Clean Boot State.

1] Replace the crypt32.dll file

Crypt32.dll is the module that implements many of the Certificate and Cryptographic Messaging functions in the CryptoAPI

The file mentioned above is located on this path-

For x86:

This PC > C:\Windows\System32.

For x64:

This PC > C:\Windows\SysWOW64.

Get the new file from another computer with the same file version number.

Then, you need to boot into Safe Mode, navigate to the path mentioned above, and replace the file.

Next, open Command Prompt by searching for cmd in the Cortana search box and run it with Administrator level privileges.

Type in the following command and hit the Enter key to re-register the dll file–

regsvr32 crypt32.dll

Reboot and see.

2] Reset Windows Update related folders

You need to delete the contents of the SoftwareDistribution folder & reset the Catroot2 folder.

3] Use Windows Update Troubleshooter

You can run the Windows Update Troubleshooter and also Microsoft’s Online Windows Update Troubleshooter and check if that is any help in fixing any of your issues.

4] Configure the Firewall or Antivirus

You can try to temporarily disable Windows Defender which is installed out of the box on your Windows 10 computer. You can also disable your Windows Firewall on your computer and check if that fixes the errors that you are encountering. If you are using 3rd-party security software, disable them and see.

5] Download the required update manually

If it’s not a feature update, and only a cumulative update, you can manually download and install the Windows Update. To find which update has failed to follow the steps:

• Go to Settings > Update and Security > View Update History
• Check which particular update has failed. Updates that have failed to install will display Failed under the Status column.
• Next, go to Microsoft Download Center, and search for that update using the KB number.
• Once you find it, download, and install it manually.

6] Use System File Checker

Open Command Prompt as administrator and run System File Checker by executing the following command:

sfc /scannow

Restart your system after the scan is completed.

You can also use our freeware FixWin to Run the System File Checker utility with a click.

7] Run Windows Updates in Clean Boot State

A Clean Boot starts a system with minimal drivers and startup programs. When you start the computer in clean boot, the computer starts by using a pre-selected minimal set of drivers and startup programs, and because the computer starts with a minimal set of drivers, some programs may not work as you expected.

You can run Windows Update after booting into the Clean Boot State and check if that makes the error go away.

All the best!
