发现Windows 更新无法^{(Windows Updates fail to download or install)}在Windows中下载或安装是另一回事。但是，如果Windows Update或Microsoft Update本身不起作用^{(does not work)}、卡在检查中，或者您打开的“控制面板^{(Control Panel)}”或“设置”中的“ ^(Settings)Windows Update”页面显示为空白^(blank)，您该怎么办。这是Windows Vista及更早版本中的常见问题，但在^{(Windows Vista)}Windows 111/0/8/7中很少有人看到此问题！不过，如果您确实遇到此问题，您可以尝试这些故障排除步骤，不分先后顺序。请记住先创建系统还原点。

Windows Update卡在 Checking for Update或不工作

请先^(Please)阅读整篇文章，然后查看哪些建议适用于您的Windows 操作系统^{(Windows OS)}版本。如果Windows 更新^{(Windows Update)}不起作用，请执行以下操作：

1.运行系统还原

首先要做的是查看您是否安装了任何新软件，如果是，请尝试将您的计算机恢复到以前的良好状态。

2.清理电脑缓存

清除您的 Temporary Files 文件夹、Cookies文件夹和Temporary Internet File 文件^{(Temporary Internet File)}夹，重新启动并重试。最好且易于使用的内置磁盘清理实用程序^{(Disk Cleanup utility)}。

3.刷新软件分发文件夹^{(Software Distribution Folder)}

^{(Run Command Prompt)}以管理员身份运行命令提示符。在计算机屏幕上出现的CMD框中，输入以下文本字符串，一次一个，然后按 Enter^(Enter)。

net stop wuauserv

net stop bits

现在浏览到 C:\Windows\SoftwareDistribution 文件夹并删除其中的所有文件和文件夹。

如果文件正在使用中，请重新启动您的设备。重新启动后，再次运行上述命令。顺便说一句，您的 Windows 应用商店应用程序^(App)需要关闭，所以不要启动它。

现在您将能够从提到的Software Distribution文件夹^{(Software Distribution folder)}中删除文件。现在在命令提示符^{(Command Prompt)}窗口中，一次输入以下命令，然后按 Enter^(Enter)：

net start wuauserv

net start bits

重启^(Reboot)。如果您使用的是Windows 更新^{(Windows Update)}，请尝试使用Microsoft 更新^{(Microsoft Updates)}，反之亦然。

4.运行证监会

运行系统文件检查器。如果发现任何损坏的系统文件，它们将在重新启动时重新启动。

5. 添加到受信任的站点

如果Windows 更新^{(Windows Update)}不起作用，请尝试以下操作：

打开 Internet Explorer > 工具 > Internet 选项 > 安全 > 单击“受信任的站点”图标 >单击站点 > 取消选中“需要服务器验证”。

然后添加以下站点：

Click Close > Apply > OK。众所周知，在某些情况下，这有助于正版验证 Windows^{(Genuine Validated Windows)}，但并非总是如此。

6. 检查是否安装了Windows 更新代理^{(Windows Update Agent)}

还要确保您安装了最新的Windows 更新代理^{(Windows Update Agent)}。

7.重新注册以下dll

尝试单独重新注册以下 dll。如果您不确定如何操作，请参阅如何注册和取消注册 dll 。

或者，打开记事本^(Notepad)。将以下命令行复制粘贴^(Copy-Paste)到其中并使用 .bat 或 .cmd 扩展名保存文件。

regsvr32 /s wuapi.dll
regsvr32 /s wuaueng.dll
regsvr32 /s wups.dll
regsvr32 /s wups2.dll
regsvr32 /s wuwebv.dll
regsvr32 /s wucltux.dll
regsvr32 /s wudriver.dll

双击^{(Double-click)}.bat或.cmd文件的图标；将打开一个命令窗口。运行命令，然后关闭。重新启动^(Reboot)，然后查看Windows 更新^{(Windows Update)}是否正常工作。

8. 检查 Internet 选项

打开IE > Tools > Internet Options > Advanced > Security Settings > Ensure启用 SSL 2^{(Enable SSL 2)} ”或“启用SSL 3 ”这两个框。

9. 参考微软^(Microsoft)的错误代码参考

转到此处查看Windows 更新错误代码的完整主列表^{(Complete Master List of Windows Update Error Codes)}。如果您在下载更新时收到 Windows Update错误 80246008，您可能需要更改后台智能传输服务^{(Background Intelligent Transfer Service)}( BITS ) 或Windows 事件日志^{(Windows Event Log)}服务设置，然后重新启动每个服务。

10.检查主机文件

如果您正在从恶意软件攻击中恢复，您可能还需要查看您的 Hosts 文件。某些恶意软件程序可能会修改主机的文件以控制DNS名称解析。从位于C\Windows\system32\drivers\etc\hosts的 Hosts 文件中删除Windows Update和Microsoft Update的^{(Microsoft Update)}所有^(ALL)条目。

11. 运行修复 WU

使用我们的Fix WU工具，看看它是否有帮助。它重新注册Windows Update正常运行所需的所有 dll、ocx 和 ax 文件。

12. 运行Windows 更新疑难解答^{(Windows Update Troubleshooter)}

使用Microsoft的Windows 更新疑难解答。它将Windows 更新^{(Windows Updates)}设置重置为默认值。

您可以删除任何包含Windows Update或Microsoft Update 条目的行，或者^{(Microsoft Update OR)}您可以在包含“microsoft”和“update”的任何行之前或前面放置数字符号 #。HostsMan是一个很好的免费软件实用程序，可帮助您管理 Hosts 文件。

Windows 更新页面空白

如果当您从控制面板^{(Control Panel)}打开 Windows 更新时，您会看到一个空白页，您可能需要重新注册以下DLL文件。众所周知，它可以工作。以管理员身份打开运行，依次键入以下内容，然后^(Run)按 Enter^(Enter)。

regsvr32 jscript

regsvr32 vbscript

regsvr32 /i mshtml

Windows更新设置^{(Update Settings)}页面为空白

如果Windows 设置^{(Windows Settings)}面板中的Windows 更新页面^{(Windows Update page)}为空白，那么您可以尝试以下建议之一：

• 重新设置^{(Reset Settings)}
• 运行 Windows 更新疑难解答
• 运行系统文件检查器
• ^{(Uninstall recent Windows Update)}如果最近更新后出现问题，请卸载最近的 Windows更新
• Reset Windows 11/10。

希望这会有所帮助！

Windows Update Not working, stuck on Checking for Updates, Page blank

It is a different thing to find that Windows Updates fail to download or install in Windows. But what can you do if Windows Update or Microsoft Update itself does not work, is stuck checking, or the Windows Update page in Control Panel or Settings that you open comes out blank. This was a common problem in Windows Vista and earlier, but fewer people see this issue in Windows 111/0/8/7! Nevertheless, if you do face this problem, you may try these troubleshooting steps, in no particular order. Do remember to create a system restore point first.

Windows Update stuck on Checking for Updates or not working

Please go through the entire post first and then see which of the suggestions apply to your version of Windows OS. If Windows Update is not working do the following:

1. Run System Restore

The first thing to do is to see if you installed any new software, and if so, try to restore your computer to a prior good time.

2. Clear up PC cache

Clear up your Temporary Files folder, Cookies folder & Temporary Internet File folder, reboot and try again. Best and easy to use the built-in Disk Cleanup utility.

3. Flush the Software Distribution Folder

Run Command Prompt as administrator. In the CMD box that appears on the computer screen, enter the following strings of text, one at a time, and hit Enter.

net stop wuauserv

net stop bits

Now browse to the C:\Windows\SoftwareDistribution folder and delete all the files and folders inside.

If the files are in use, restart your device. After rebooting, run the commands above again. Your Windows Store App needs to be closed, by the way, so do not start it.

Now you will be able to delete the files from the mentioned Software Distribution folder. Now in the Command Prompt windows, type the following commands one at a time, and hit Enter:

net start wuauserv

net start bits

Reboot. If you are using Windows Update, try using Microsoft Updates or vice versa.

4. Run SFC

Run system file checker. If any corrupt system files are found, they will be repaced on reboot.

5. Add to Trusted Sites

If Windows Update is not working, try this :

Open Internet Explorer > Tools >Internet Options > Security > Click ‘trusted sites’ icon >Click Sites > uncheck ‘Require server verification’.

Then add the following sites :

Click Close > Apply > OK. This is known to help the Genuine Validated Windows, in some cases, but not always.

6. Check if Windows Update Agent is installed

Do also ensure that you have the latest Windows Update Agent installed.

7. Re-register the following dlls

Try to re-register the following dlls individually. See how to register & unregister dll‘s if you are not sure how to do it.

Alternatively, open Notepad. Copy-Paste the following command lines into it and save the file using a .bat or .cmd extension.

regsvr32 /s wuapi.dll
regsvr32 /s wuaueng.dll
regsvr32 /s wups.dll
regsvr32 /s wups2.dll
regsvr32 /s wuwebv.dll
regsvr32 /s wucltux.dll
regsvr32 /s wudriver.dll

Double-click the icon of the .bat or .cmd file; a command window will open. Run the commands, and then close. Reboot, and see if Windows Update is working OK.

8. Check Internet Options

Open IE > Tools > Internet Options > Advanced > Security Settings > Ensure that the two boxes “Enable SSL 2” or “Enable SSL 3” are checked.

9. Refer Microsoft for error code references

Go here to see the Complete Master List of Windows Update Error Codes. If you receive Windows Update error 80246008 while downloading updates, you might need to change the Background Intelligent Transfer Service (BITS) or Windows Event Log service settings, and then restart each service.

10. Check Hosts file

If you are recovering from a malware attack, you may also want to have a look at your Hosts file. Some malware programs may modify the host’s file to control DNS name resolution. Remove ALL entries for Windows Update and Microsoft Update from your Hosts file situated at C\Windows\system32\drivers\etc\hosts.

11. Run Fix WU

Use our Fix WU tool and see if it helps. It re-registers all the dll, ocx and ax files required for the proper functioning of Windows Update.

12. Run Windows Update Troubleshooter

Use the Windows Update Troubleshooter from Microsoft. It resets Windows Updates settings to defaults.

You can either remove any lines that contain entries for Windows Update or for Microsoft Update OR you can just place the number sign # before or in front of any line that contains “microsoft” and “update”. HostsMan is a good freeware utility to help you manage your Hosts file.
