有时，用户在使用Windows Update时会遇到问题。虽然有多种方法可以解决各种Windows 更新^{(Windows Update)}问题，但如果这种情况经常发生，最好将Windows 更新^{(Windows Update)}设置重置为默认设置。如果您的Windows 更新安装失败，^{(Windows Updates fail to Install)}这会很有用。

我们已经了解了如何使用重置 Windows 更新组件工具将 Windows 更新重置^{(Reset Windows Update Components Tool)}为默认值^{(reset Windows Update to default)}。我们的Fix WU 实用程序重新注册所有与Windows 更新^{(Windows Update)}相关的 dll 文件并将其他设置重置为默认值。但是，如果您想知道如何在Windows 11/10/8/7Windows Update组件单独重置为默认值，那么这篇文章就是您要找的。

^{(Reset Windows Update Components)}在Windows 11/10重置 Windows 更新组件

Windows 11/10更新组件^{(Windows Update Components)}重置为默认值所需采取的所有步骤的摘要：

1. 停止 Windows 更新服务
2. 删除qmgr*.dat文件。
3. 刷新SoftwareDistribution和 catroot2 文件夹
4. 将BITS^(BITS)服务和Windows 更新^{(Windows Update)}服务重置为默认安全描述符
5. 重新注册^{(Re-register)}BITS文件和Windows Update相关的DLL文件
6. 删除不正确的注册表值
7. 重置温索克
8. 重新启动 Windows 更新服务。

1]停止Windows更新服务

首先，您需要停止后台智能传输、Windows 更新、加密服务^{(stop the Background Intelligent Transfer, Windows Update, Cryptographic Services)}。这些服务基本上允许Windows下载^(Windows)自动 Windows 更新^{(Automatic Windows Update)}和其他Windows组件使用的所有文件和更新。当您的连接空闲时，它会使用网络连接的空闲带宽，并在后台静默下载文件。因此，最好在继续之前禁用BITS服务。^(BITS)

为此，请在提升的命令提示符窗口中键入以下命令，并在键入每个命令后按 Enter。

net stop bits

net stop wuauserv

net stop appidsvc

net stop cryptsvc

2] 删除 qmgr*.dat 文件

接下来，您需要delete the qmgr*.dat files。为了重置Windows 更新^{(Windows Update)}组件，您需要删除这些文件。为此，请在命令提示符处键入以下命令，然后按 Enter：

Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat"

在这里值得一提的是，如果这是您第一次尝试按照本文中的步骤解决Windows 更新^{(Windows Update)}问题，建议您跳过这一步并直接跳到下一步。尽管尝试了文章中概述的所有步骤，但此步骤除外，因为该步骤是由Fix it Solution的“积极”模式执行的，但仅当您看不到解决方案时才应遵循该步骤进行故障排除。

3]刷新^(Flush)SoftwareDistribution和 catroot2 文件夹

How to reset Windows Update components in Windows 11/10

At times, users exрerience trouble using Windows Update. While there arе several ways to troubleshoot various Windows Update issuеs, if this happens frequently, it would be a good idea to reset Windows Update settings to defаult. Thiѕ can be useful if your Windows Updates fail to Install.

We have already seen how to reset Windows Update to default using the Reset Windows Update Components Tool. Our Fix WU Utility re-registers all Windows Update related dll files and resets other settings to default. But if you want to know how to manually reset each Windows Update component individually to default in Windows 11/10/8/7, then this post is what you are looking for.

Reset Windows Update Components in Windows 11/10

Here is the summary of all the steps you need to take to reset Windows Update Components to defaults in Windows 11/10:

1. Stop Windows Update Services
2. Delete the qmgr*.dat files.
3. Flush the SoftwareDistribution and catroot2 folders
4. Reset the BITS service and the Windows Update service to the default security descriptor
5. Re-register the BITS files and the Windows Update related DLL files
6. Delete incorrect Registry values
7. Reset Winsock
8. Restart Windows Update Services.

1] Stop Windows Update Services

First you will need to stop the Background Intelligent Transfer, Windows Update, Cryptographic Services. The services basically allow Windows to download all files and update that are used by Automatic Windows Update and other Windows components. It uses the idle bandwidth of network connection when your connection is idle and silently downloads files in the background. It is, therefore, the best practice to disable the BITS service before proceeding.

To do so, in an elevated command prompt window, type the following commands and press Enter after you type each command.

net stop bits

net stop wuauserv

net stop appidsvc

net stop cryptsvc

2] Delete the qmgr*.dat files

Next, you need to delete the qmgr*.dat files. In order to reset Windows Update components, you will need to delete the files. To do this, at a command prompt, type the following command, and then press Enter:

Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat"

It’s worth mentioning here that if this is the first time you are trying to resolve your Windows Update issues by following the steps in this post, it is advisable to skip this very step and jump directly to the next step. The step should only be followed for troubleshooting when you see no solution in sight despite trying all steps outlined in the article except this step since the step is performed by the “Aggressive” mode of the Fix it Solution.

3] Flush the SoftwareDistribution and catroot2 folders

Rename the SoftwareDistribution and catroot2 folders. To do this, at a command prompt, type the following commands. Make sure that you press Enter after you type each command.

Ren %systemroot%\SoftwareDistribution SoftwareDistribution.bak

Ren %systemroot%\system32\catroot2 catroot2.bak

Read: Windows Update keeps disabling itself automatically.

4] Reset the BITS service and the Windows Update service to the default security descriptor

To do this, at a command prompt, type the following commands. Make sure that you press Enter after you type each command.

sc.exe sdset bits D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)

sc.exe sdset wuauserv D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)

Now, in the command prompt window that is opened, type the following command, and then press Enter:

cd /d %windir%\system32

5] Re-register the BITS files and the Windows Update related DLL files

Re-register the BITS files and the Windows Update related dll files, in the command prompt window, type the following commands. Do not forget to hit the Enter key after every command you type.

regsvr32.exe atl.dll

regsvr32.exe urlmon.dll

regsvr32.exe mshtml.dll

regsvr32.exe shdocvw.dll

regsvr32.exe browseui.dll

regsvr32.exe jscript.dll

regsvr32.exe slbcsp.dll

regsvr32.exe cryptdlg.dll

regsvr32.exe oleaut32.dll

regsvr32.exe ole32.dll

regsvr32.exe shell32.dll

regsvr32.exe initpki.dll

regsvr32.exe wuapi.dll

regsvr32.exe wuaueng.dll

7] Reset Winsock

It is a technical specification that defines how Windows network software should access network services, especially TCP/IP. Windows OS comes with a Dynamic Link Library (DLL) file called winsock.dll which implements the API and coordinates Windows programs and TCP/IP connections. Due to some reason, Windows Sockets popularly referred to as Winsock may get corrupted. As such, a user may experience difficulty in establishing a connection to the Internet. It, therefore, becomes necessary to repair Winsock by resetting it.

To Reset Winsock, in the command prompt window, type the following command, and then press Enter:

netsh winsock reset

TIP: Reset Windows Update Tool will restore settings & components to default automatically.

8] Restart Windows Update Services

Once all is done, restart the BITS service, the Windows Update service, and the Cryptographic service. To do this, switch back to the command prompt and enter the following commands. Again, make sure that you press Enter after you type each command.

net start bits

net start wuauserv

net start appidsvc

net start cryptsvc

Finally, make sure that you have installed the latest Windows Update Agent on your computer.

Restart your computer to complete the process.
