在 Windows 8.1 中，有两种Windows 更新^{(Windows Update)}工具：一种可从桌面^(Desktop)获得（自Windows 7以来未更改），另一种在PC 设置^{(PC Settings)}中，针对使用触摸设备的用户进行了优化。使用PC 设置^{(PC Settings)}版本时，您可以查看有关可用更新的信息、手动检查新更新、安装可用更新、查看更新历史记录以及选择如何在Windows 8.1中安装更新。以下是它的工作原理：

如何从PC 设置^{(PC Settings)}访问 Windows 更新^{(Access Windows Update)}

首先，打开电脑设置^{(PC Settings)}。如果您不知道如何操作，请阅读本教程：访问 PC 设置的^{(Access PC Settings)}六种^(Six)方法。

当PC 设置^{(PC Settings)}窗口打开时，单击或点击更新和恢复^{(Update and recovery)}部分。

接下来，按Windows 更新^{(Windows Update)}。

打开自动^(Automatic)更新时如何使用Windows 更新^{(Windows Update)}

如果您在 Windows 8.1 设备的初始配置期间遵循Microsoft的建议，您将启用自动更新。虽然这是出于安全原因的最佳做法，并且可以及时安装重要的补丁和产品升级，但它也限制了您可以在PC 设置^{(PC Settings)}更新界面中执行的操作。如果您启用了自动更新，您将看到一条消息，通知您这一事实：“您已设置为自动安装更新”^{("You're set to automatically install updates")}。

如果您当前有计划安装的更新，您将看到一条消息指示^{(message indicating)}。

单击查看详细信息^{(View details)}以获取更多信息。

在查看详细信息^{(View details)}窗口中，您可以按Install手动强制安装。

无论^(Whether)当前是否计划安装更新，您都可以通过按立即检查^{(Check now)}来检查更新。

如果找到更新，PC 设置^{(PC Settings)}将礼貌地通知您，它将根据您预先安排的时间表安装更新。

如何在未打开自动更新的情况下使用 Windows 更新^{(Windows Update Without Automatic Updates)}

如果您没有配置更新，请单击或点击^{(click or tap)} “选择如何安装更新”^{("Choose how updates get installed")}。

在这里，您可以选择自动检查更新。此外，您可以选择自动下载并安装它们，也可以选择自动下载并选择何时安装它们。

无论您选择什么，您都可以通过按Install继续安装所有重要更新。如果您更愿意选择要安装的更新，请单击查看详细信息^{(View details)}以获取更多信息。

现在显示所有可用的更新。对于他们每个人，您都可以看到他们的名字。如果您想查看更新的描述，请单击或点击其名称附近的详细信息^(Details)链接。

结论

您很可能已经注意到，如果您启用了自动更新，则不一定非要使用PC 设置中的^{(PC Settings)}Windows 更新^{(Windows Update)}工具。毕竟，这就是自动更新的意义所在，它只是发生了，你不必考虑它。但是，如果您更喜欢自己控制更新，或者您想确保自动更新正常工作，那么这是快速完成更新的好方法。您如何管理您在Windows 8.1中的更新？如果您遇到此主题的问题或对此有其他想法，请在下方给我们留言。

How to Use Windows Update from Windows 8.1's PC Settings

In Windows 8.1 there are two Windows Update tools: one available from the Desktop (which hasn't changed since Windows 7) and one in PC Settings, that's optimized for users with touch devices. When using the PC Settings version, you can view information about available updates, check for new updates manually, install those that are available, view your update history, and choose how updates get installed in Windows 8.1. Here's how it all works:

How to Access Windows Update from PC Settings

First, open PC Settings. If you don't know how, read this tutorial: Six Ways to Access PC Settings.

When the PC Settings window opens, click or tap the Update and recovery section.

Next, press Windows Update.

How to Use Windows Update when Automatic Updates are Turned On

If you followed Microsoft's recommendations during the initial configuration of your Windows 8.1 device, you'll have automatic updates enabled. While this is a best practice for security reasons and results in timely installation of important patches and product upgrades, it also limits what you can do in the PC Settings update interface. If you have auto-updating enabled you'll see a message informing you of that fact: "You're set to automatically install updates".

If you have updates currently scheduled for installation, you'll see a message indicating that.

Click View details for a bit more information.

From the View details window, you can manually force the installation by pressing Install.

Whether or not updates are currently scheduled for installation, you have the option to check for updates by pressing Check now.

If updates are found, PC Settings will politely inform you that it will install the updates according to your prearranged schedule.

How to Use Windows Update Without Automatic Updates Turned On

If you don't have updates configured click or tap "Choose how updates get installed".

Here, you can select to automatically check for updates. Also, you can choose either to download and install them automatically or to download them automatically and choose when to install them.

Whatever you select you can go ahead and install all important updates by pressing Install. If you'd rather pick and choose which updates to install, click View details for more information.

All the available updates are now displayed. For each of them you can see their name. If you want to view a description of an update, click or tap the Details link near its name.

Conclusion

Most probably you have noticed that the Windows Update tool in PC Settings isn't necessarily imperative to use if you have automatic updates enabled. After all, that is the point of auto-updating, it just happens and you don't have to think about it. But, if you prefer to control your updates yourself, or you want to ensure that auto-updating is doing its job, this is a good way to get it done quickly.
