如果您将 PC 连接到 Internet，则需要使其保持最新状态。Microsoft会定期发布重要的(Microsoft)Windows 10安全更新、错误修复和新功能版本，以改善整体用户体验。如果您不更新Windows，您的 PC（以及其中保存的数据）将面临风险。
大多数情况下，Windows无需任何用户输入即可处理更新过程。然而，有时，Windows 只是不会安装更新(Windows just won’t install updates)，让它们陷入困境。如果您想在Windows 10更新卡住时进行修复，您需要执行以下操作。
给它时间（然后强制重启）(Give It Time (Then Force A Restart))
这似乎是问题的明显答案，但有时当Windows 10更新卡住时，最简单的解决方案就是给它一些额外的时间。进度条可能不会移动，但这并不一定意味着什么都没有发生。
Windows 每月发布累积更新，将其他更新版本捆绑到一个易于安装的下载和安装中。您还将看到每年两次发布的更大的功能更新。
这些是对Windows操作系统的重大更新，包括新功能和对整体用户体验的更改，以及重要的错误修复。这些更新可能很大并且可能需要一些时间才能完成。
如果您的Windows 10 更新卡住了一个小时或更长时间，请强制重新启动。仅当您的 PC 确实没有响应时才执行此操作，因为在更新周期中间重新启动可能会破坏您的系统，迫使您重新安装Windows以重新运行。
运行 Windows 更新疑难解答(Run Windows Update Troubleshooter)
虽然Windows非常擅长自行解决更新问题，但使用内置的Windows 疑难解答(Windows Troubleshooter)工具来帮助诊断和修复系统的任何问题会很有用。
- 您可以从Windows 设置(Windows Settings)菜单中找到并运行此工具。要运行它，请右键单击Windows 开始(Windows Start)菜单，然后单击设置(Settings)。从那里，单击更新和安全(Update & Security )>故障排除(Troubleshoot)以访问故障排除工具。
- 如果Windows为您提供任何即时建议，包括帮助改进更新体验的提示，这些将列在“疑难解答(Troubleshoot)”菜单顶部的“推荐的疑难解答”部分下。(Recommended troubleshooting )
- 要运行Windows 10 更新疑难解答(Update Troubleshooter)，请单击启动并运行(Get up and running )部分下的Windows 更新(Windows Update)，然后按运行疑难解答(Run the troubleshooter)以启动该工具。
- 该工具将在新窗口中启动，并自动开始检查您的 PC 是否存在问题。如果它可以发现更新卡住的问题，它会自动为您解决此问题，或通知您下一步该做什么。如果Windows未检测到任何问题，它会邀请您提供反馈或关闭该工具。
Windows 疑难解答(Windows Troubleshooter)无法解决所有问题，但如果检测到明显问题，它会尝试解决它。如果不能，您需要尝试以下步骤之一。
删除临时 Windows 更新文件(Delete Temporary Windows Update Files)
有时可以通过删除Windows为更新下载的临时文件来修复损坏的Windows 10更新。这可能会强制Windows再次下载文件，然后尝试重新安装。
如果Windows 10更新由于文件损坏或损坏而卡住，这应该可以解决问题。
- 为此，您首先需要禁用一些与Windows Update相关的Windows服务。为此，请右键单击Windows 开始(Windows Start)菜单，然后单击Windows PowerShell (Admin)。在打开的PowerShell窗口中，键入net stop wuauserv和net stop bits以首先禁用这些服务。
- 禁用这些服务后，键入Remove-Item -path c:\Windows\SoftwareDistribution。这将删除包含临时Windows更新文件的文件夹。输入Y或A进行确认。您也可以使用Windows 文件资源管理器(Windows File Explorer)手动删除这些文件。
- 此过程完成后，键入net start wuauserv和net start bits以重新启动Windows 更新(Windows Update)服务。
- 然后，您可以通过右键单击“开始(Start)”菜单并单击“设置”(Settings)再次手动检查更新。从那里，单击Windows Update > Check for Updates以访问和运行Windows 更新(Windows Update)。如果之前的更新失败，这应该会强制Windows再次下载更新并尝试重新安装。
从 Microsoft 更新目录手动更新您的电脑(Manually Update Your PC From Microsoft Update Catalog)
下载并手动更新您的 Windows 10 PC 有时可以解决Windows Update的问题。您可以使用Microsoft 更新目录(Microsoft Update Catalog)网站(Microsoft Update Catalog website)查找新的更新。
不要让过时的界面让您感到困惑，因为它包含Windows为其桌面和服务器操作系统发布的所有更新。您需要知道要查找的更新的参考代码，或者您可以按更新名称搜索（例如，Windows 10 累积更新）。
- 使用Microsoft 更新目录(Microsoft Update Catalog)网站上的搜索工具搜索更新。找到要查找的更新后，单击“下载(Download)”按钮。
- 下载后，打开包含更新的存档文件并将其解压缩。每个更新都应该包含一个安装可执行文件——双击它来运行更新。
- 按照屏幕上的说明进行更新（如果需要）。更新完成后，返回Windows 更新(Windows Update)（Windows Settings > Update & Security > Windows Update）并检查是否有任何其他更新。
如果单个更新导致问题，那么这应该允许您继续进行进一步的更新。但是，如果不止一个更新被破坏，那么这可能是一个耗时的修复，您可能需要查看其他选项。
使用系统还原恢复 Windows 安装(Revert Your Windows Installation Using System Restore)
无法始终修复损坏的Windows 10更新，尤其是当您的(Windows 10)Windows安装出现问题时。要解决此问题，您可以使用 Windows 系统还原(use Windows System Restore)将Windows恢复到早期的时间点。
- 要访问您的系统还原点(System Restore)，请按Win + R打开“运行”(Run)对话框。从这里输入sysdm.cpl SystemProperties并单击OK。
- 在“系统属性(System Properties)”窗口中，单击“系统还原”(System Restore)。
- 在“系统还原”(System Restore)窗口中，单击“下一步”(Next)，然后选择更新失败之前的Windows 还原点。(Windows Restore)单击(Click) 下一步(Next)继续。
- 单击完成(Finish )进行确认。这会将Windows(Windows)还原到您选择的上一个时间点。
还原过程完成后，您应该能够重新运行Windows 更新(Windows Update)。但是，如果问题没有得到解决，您可能需要查看擦除并重新安装 Windows(wiping and reinstalling Windows)以使您的系统再次正确更新。
保持 Windows 更新(Keeping Windows Updated)
如果没有更新，您将不得不处理错误、恶意软件感染(malware infections)和缺少的功能。Windows 10 是一个滚动发布操作系统，这意味着它会继续更新和开发以改善用户体验。您的Windows 10 更新可能需要很长时间(Windows 10 updates may take forever)，但这不是禁用它们的理由。
如果您遇到问题，那么借助第三方软件，您可以完全绕过微软自己的系统，在没有 Windows Update 的情况下更新 Windows 。(updating Windows without Windows Update)但是，在大多数情况下，您最好让Windows去做它的事情，并按照上述步骤来解决Windows 10 更新损坏或卡住的任何最常见问题。
How To Fix a Stuck Windows 10 Update
If you’re connecting your PC to the internet, you’ll need to keep it up-tо-date. Microsoft regularly issues important sеcurity updates, bug fixes, and new feature releases fоr Windows 10 to improve the overall user experience. If you don’t keep Windows updated, you’ll be putting your PC (and the data held on it) at risk.
Most of the time, Windows can handle the update process without any user input. From time to time, however, Windows just won’t install updates, leaving them stuck in limbo. If you want to fix when a Windows 10 update is stuck, here’s what you’ll need to do.
Give It Time (Then Force A Restart)
It might seem like the obvious answer to the problem, but sometimes the easiest solution when a Windows 10 update is stuck is just to give it a bit of extra time. The progress bar might not be moving, but that doesn’t necessarily mean that nothing is happening.
Windows releases monthly cumulative updates that bundle together other update releases into a single, easy-to-install download and installation. You’ll also see much larger feature updates released on a twice-yearly basis.
These are big updates to the Windows operating system that include new features and changes to the overall user experience, as well as important bug fixes. These updates can be big and can take time to complete.
If your Windows 10 update is stuck for an hour or longer, then force a restart. Only do this if your PC really isn’t responding, as restarting in the middle of an update cycle can break your system, forcing you to reinstall Windows to get things running again.
Run Windows Update Troubleshooter
While Windows is pretty good at resolving issues with updates on its own, it can be useful to turn to the built-in Windows Troubleshooter tool to help diagnose and fix any problems with your system.
- You can find and run this tool from the Windows Settings menu. To run this, right-click the Windows Start menu and click Settings. From there, click Update & Security > Troubleshoot to access the troubleshooting tool.
- If Windows has any immediate recommendations for you, including tips to help improve the update experience, these’ll be listed under the Recommended troubleshooting section at the top of the Troubleshoot menu.
- To run the Windows 10 Update Troubleshooter, click Windows Update under the Get up and running section, then press Run the troubleshooter to begin the tool.
- The tool will begin in a new window, and will automatically begin checking your PC for problems or issues. If it can find a problem with a stuck update, it’ll fix this for you automatically, or inform you on what to do next. If Windows detects no problems, it’ll invite you to give feedback or close the tool.
The Windows Troubleshooter can’t fix every problem, but if an obvious issue is detected, it will attempt to resolve it. If it can’t, you’ll need to try one of the steps below instead.
Delete Temporary Windows Update Files
A broken Windows 10 update can sometimes be fixed by deleting the temporary files that Windows downloads for updates. This can force Windows to download the files again, then attempt a reinstallation.
If the Windows 10 update is stuck because of broken or corrupted files, this should resolve the problem.
- To do this, you’ll first need to disable some Windows services related to Windows Update. To do this, right-click the Windows Start menu and click Windows PowerShell (Admin). In the PowerShell window that opens, type net stop wuauserv and net stop bits to first disable these services.
- Once these services are disabled, type Remove-Item -path c:\Windows\SoftwareDistribution. This will delete the folder containing your temporary Windows update files. Type Y or A to confirm. You can also delete these files manually using Windows File Explorer.
- Once this process is complete, type net start wuauserv and net start bits to restart your Windows Update services.
- You can then check for updates again manually by right-clicking the Start menu and clicking Settings. From there, click Windows Update > Check for Updates to access and run Windows Update. If an update has previously failed, this should force Windows to download the update again and attempt to reinstall it.
Manually Update Your PC From Microsoft Update Catalog
Downloading and manually updating your Windows 10 PC can sometimes get around issues with Windows Update. You can look for new updates using the Microsoft Update Catalog website.
Don’t let the outdated interface confuse you, as this contains all updates released by Windows for its desktop and server operating systems. You’ll need to know the reference code for the update you’re looking for, or you can search by the update name (for instance, Windows 10 cumulative update).
- Search for the update using the search tool on the Microsoft Update Catalog website. Once you’ve found the update you’re looking for, click the Download button.
- Once downloaded, open the archive file containing your update and extract it. Each update should contain a setup executable file—double click this to run the update.
- Follow the instructions on-screen for your update (if required). Once the update has completed, return to Windows Update (Windows Settings > Update & Security > Windows Update) and check for any additional updates.
If a single update is causing the problem, then this should allow you to proceed with further updates. If more than one update is broken, however, then this could be a time-consuming fix, and you may need to look at other options.
Revert Your Windows Installation Using System Restore
A broken Windows 10 update can’t always be fixed, especially if there’s a problem with your Windows installation. To get around this problem, you can use Windows System Restore to revert Windows back to an early point in time.
- To access your System Restore points, press Win + R to open the Run dialog box. From here, type sysdm.cpl SystemProperties and click OK.
- In the System Properties window, click System Restore.
- In the System Restore window, click Next, then select a Windows Restore point before your failed update. Click Next to continue.
- Click Finish to confirm. This will restore Windows to the previous point in time you selected.
Once the restore process is complete, you should be able to run Windows Update again afresh. If the problem isn’t resolved, however, you may need to look at wiping and reinstalling Windows to get your system updating correctly again.
Keeping Windows Updated
Without updates, you’ll be left dealing with bugs, malware infections, and missing features. Windows 10 is a rolling release operating system, meaning it continues to be updated and developed for an improved user experience. Your Windows 10 updates may take forever, but that’s no reason to disable them.
If you are having problems, then you can bypass Microsoft’s own systems entirely by updating Windows without Windows Update, thanks to third-party software. In most cases, however, you’re best leaving Windows to do its thing, and following the steps above to troubleshoot any of the most common issues with broken or stuck Windows 10 updates.
