Windows自行安装更新通常不会出现零问题。但有时用户设置或其他潜在问题会阻止Windows完成其工作。在这篇文章中，我们将讨论您可以执行的一些操作以再次进行 Windows安装更新。

重启你的电脑

简单的系统重启有时可以解决更新错误。因此，在您尝试其他任何操作之前，请重新启动您的电脑，看看是否能解决问题。

如果没有，您可以尝试以下其他解决方案。

检查您的设置

某些Windows 设置可能会阻止它安装必要的更新。以下是您应该检查的一些事项。

计量连接

Windows 具有阻止它通过计量连接下载更新的功能。您应该检查您的 Wi-Fi 设置，看看这是否是导致问题的原因。

转到Windows 设置^{(Windows Settings)}>网络和 Internet^{(Network & Internet)} > Wi-Fi。单击您当前连接的Wi-Fi 。查看 Metered Connection 下的Set ^{(Metered Connection)}As Metered Connection^{(Set As Metered Connection)}是否已打开。

有很多原因可以让您保持开启状态，尤其是如果您使用的是有限的互联网计划并且不想产生额外费用。但将其关闭将确保您在 Windows 更新准备就绪后立即获得它们。

Windows更新

如果您想接收更新，无论您的连接是否设置为按流量计费的连接，您都需要更改您的Windows 更新^{(Windows Update)}设置。

转到Windows 设置^{(Windows Settings)}>更新和安全^{(Update and Security)}> Windows 更新^{(Windows Update)}>高级选项^{(Advanced Options)}。

在Update Options下，打开Automatically Download Updates, Even Over Metered Data Connections。请注意，打开此功能可能会导致收费，具体取决于您的网络提供商。

Windows 更新疑难解答

Windows 10 创建了一个处理更新问题的程序。它称为Windows 更新^{(Windows Update)} 疑难解答程序，它将通过您的 PC 并查找阻止Windows 更新^{(Windows Update)}正常工作的错误。

下载 Windows 更新疑难解答^{(Download Windows Update Troubleshooter)}并在安装后运行该应用程序。完成后，重新启动计算机。接下来，转到Windows 设置^{(Windows Settings)}>更新和安全^{(Update and Security)}> Windows 更新^{(Windows Update)}。

单击检查更新^{(Check for Updates)}以查看是否有任何更新。Windows 应该开始下载和安装更新。

添加磁盘空间

^(Windows)如果您的计算机没有足够的磁盘空间，Windows将无法安装更新。如果硬盘驱动器中没有更多空间用于系统更新，请考虑添加更多空间。作为替代方案，您还可以执行磁盘清理。

搜索磁盘清理^{(Disk Cleanup)}实用程序并运行该程序。选择^(Choose)您要清理的驱动器。选择一个驱动器并点击确定。

磁盘清理^{(Disk Cleanup)}将计算可以释放多少磁盘空间。选择^(Select)您要删除的文件，然后单击“确定”继续。

寻找恶意软件

您遇到的情况极有可能是由恶意软件引起的。要检查，请运行您的防病毒软件^{(run your antivirus software)}。如果检测到恶意软件，则隔离^(Quarantine)恶意软件以防止更多损害。

重新启动 Windows 更新

如果 Windows 更新服务未按应有的方式安装更新，请尝试手动重新启动程序。

启动Search并输入Command Prompt。右键单击并选择以管理员身份运行^{(Run as Administrator)}。键入以下命令，然后按 Enter：

NET STOP WUAUSERV

命令提示符将运行该命令。完成后，它将显示一条消息，说明 Windows 更新^{(Windows Update)}已停止。输入以下命令：

NET START WUAUSERV

此命令将重新启动Windows 更新^{(Windows Update)}。转到Windows 设置^{(Windows Settings)}>更新和安全^{(Update and Security)}> Windows 更新^{(Windows Update)}，看看现在是否可以安装更新。

Windows Update Won’t Install Updates? How to Fix This Issue

Windows would normally havе zero problems installing an update on its own. But there are times when user sеttings or other underlying issues preνent Windows from doing its jоb. In this post, we’ll discυss some of the things you can dо tо makе Wіndows install updates again.

Restart your PC

A simple system restart can sometimes resolve update errors. So before you try anything else, reboot your PC and see if that will take care of the problem.

If not, you can try the other solutions below.

Check Your Settings

Some Windows settings can stop it from installing necessary updates. Here are some of the things you should check.

Metered Connection

Windows have features that prevent it from downloading updates over a metered connection. You should go over your Wi-Fi settings and see if this is what’s causing the problem.

Go to Windows Settings > Network & Internet > Wi-Fi. Click the Wi-Fi you’re currently connected to. Look under Metered Connection and see if Set As Metered Connection turned on.

There are plenty of reasons why you’d want to leave this on, especially if you are on a limited internet plan and don’t want to incur extra charges. But turning it off will make sure you get Windows updates as soon as they’re ready.

Windows Update

If you’d like to receive updates regardless of whether your connection is set as a metered one or not, you need to over your Windows Update settings.

Go to Windows Settings > Update and Security > Windows Update > Advanced Options.

Under Update Options, turn on Automatically Download Updates, Even Over Metered Data Connections. Be aware that turning this on might lead to charges depending on your network provider.

Windows Update Troubleshooter

Windows 10 has created a program that deals with update issues. It’s called Windows Update Troubleshooter and it will go through your PC and look for bugs that are preventing Windows Update from working as it should.

Download Windows Update Troubleshooter and run the application after it’s installed. Once finished, restart your computer. Next, go to Windows Settings > Update and Security > Windows Update.

Click Check for Updates to see if there are any. Windows should start downloading and installing updates.

Add Disk Space

Windows won’t be able to install updates if your computer does not have enough disk space. Consider adding more space if there’s no more room in your hard drive for a system update. As an alternative, you can also perform disk cleanup.

Search for the Disk Cleanup utility and run the program. Choose which drive you’d like to clean up. Select a drive and hit OK.

Disk Cleanup will calculate how much disk space can be freed. Select which files you’d like to delete and hit OK to continue.

Look for Malware

There’s a small possibility that what you’re experiencing is being caused by malware. To check, run your antivirus software. Quarantine malware if detected to prevent more damage.

Restart Windows Update

If the Windows Update service is not installing updates as it should, try manually restarting the program.

Launch Search and type Command Prompt. Right-click and select Run as Administrator. Type the following command then press Enter:

NET STOP WUAUSERV

The Command Prompt will run the command. Once finished, it will display a message saying Windows Update had been stopped. Enter the following command:

NET START WUAUSERV

This command would restart Windows Update. Go to Windows Settings > Update and Security > Windows Update and see if the updates can be installed now.
