作为Windows(Windows) PC上的众多系统进程之一， Windows Modules Installer Worker在(Windows Modules Installer Worker)Windows的运行方式中起着至关重要的作用。您可能还不知道，但此过程有助于确保Windows 更新(Windows Update)服务正常工作。就像(Just)ntoskrnl.exe和其他程序一样，您无法停止或禁用它。
这并不意味着您不应该对Windows Modules Installer Worker进程的确切作用以及它是否安全感兴趣，尤其是当您在Task Manager中看到它的(Task Manager)CPU使用率很高时。为了帮助您，以下是您需要了解的有关此重要过程的信息，包括出现问题时如何对其进行故障排除。
什么是 Windows Modules Installer Worker？(What Is Windows Modules Installer Worker?)
Windows Modules Installer Worker (tiworker.exe) 进程(Windows Modules Installer Worker (tiworker.exe) process)是Windows Update服务的一部分，可让您的 PC 保持最新状态。当Windows Update在您的 PC 上扫描、下载和安装更新时，Windows Modules Installer Worker进程将运行。
当更新后Windows(Windows)启动时，该服务也将在后台运行，完成 PC 的更新后配置。大多数情况下，您无需过多关注 tiworker.exe，因为该进程无需您做太多操作即可运行（除非您手动安装更新）。
考虑到Windows Update作为Windows组件的重要性，可以说Windows Modules Installer Worker进程可以安全运行。如果进程正在运行，则尝试结束进程，或以任何方式对其进行干扰，可能会导致可能导致Windows 更新中断(broken Windows updates)的问题。
无法(isn’t possible)在Windows 10中禁用Windows 更新(Windows Update)服务，包括 tiworker.exe。如果您尝试这样做，它可能会产生意想不到的副作用，包括破坏其他Windows进程，或者在最坏的情况下，阻止您的 PC 运行。
是什么导致 Windows Modules Installer Worker 高 CPU 使用率问题？(What Causes Windows Modules Installer Worker High CPU Usage Issues?)
与其他系统进程（例如csrss.exe ）不同，可以公平地说，您可能需要预期Windows Modules Installer Worker进程的CPU使用率较高。Windows 更新(Windows Update)服务将使用大量系统资源，尤其是在安装主要更新时。
这是不可避免的，但对您 PC 的影响将取决于您可用的系统资源。如果正在安装Windows更新，建议关闭其他正在运行的应用程序并允许该过程完成。这将确保对您的 PC 的要求较低。
由于 tiworker.exe 仅在准备或安装更新时由Windows使用，因此您可以将CPU、RAM或磁盘使用的任何问题追溯到Windows 更新(Windows Update)服务。
Windows完成更新后，Windows Modules Installer Worker进程应恢复正常或完全停止，直到再次需要它为止。如果没有，您将需要对Windows 更新(Windows Update)进行故障排除以尝试解决问题。
解决 Windows 更新问题(Troubleshooting Windows Update Issues)
当Windows 更新(Windows Update)出现问题时，您会在任务管理器中看到(Task Manager)Windows Modules Installer Worker进程处于紧张状态。如果是这种情况，您可以从Windows 设置(Windows Settings )菜单 检查Windows 更新(Windows Update)的当前状态（并进一步排除故障） 。
- 要检查Windows Update的当前状态，请右键单击“开始(Start)”菜单并选择“设置”(Settings )选项。这将打开Windows 设置(Windows Settings )菜单。
- 在Windows 设置(Windows Settings)中，选择Update & Security > Windows Update。如果有任何更新正在进行中（或更新未能更新），这些将列在“更新状态”(Update Status)部分下。您可以通过选择查看更新历史记录(View update history )选项来检查以前更新的状态。
- 如果更新失败（或者无法安装），您可以使用Windows 疑难解答(Windows Troubleshooter)来调查问题。在Windows 设置(Windows Settings )菜单中，选择Update & Security > Troubleshoot > Additional troubleshooters 以访问疑难解答(Troubleshooter )菜单。
- 在“其他疑难解答(Additional troubleshooters )”菜单中，选择“ Windows 更新”(Windows Update )选项以开始对Windows 更新(Windows Update)服务（包括链接的Windows 模块安装程序工作(Windows Modules Installer Worker)进程）进行疑难解答，然后选择“运行疑难解答”(Run troubleshooter )按钮进行确认。

- 如果要查看有关Windows 更新(Windows Update)的详细信息，可以在该过程完成后选择查看详细信息选项。(View detailed information )这将为您提供它完成的检查的细分，使您能够查明该服务的任何潜在问题。
如何检查 Windows Modules Installer Worker 是否为正版系统进程(How to Check If Windows Modules Installer Worker is a Genuine System Process)
在某些情况下，恶意软件会尝试通过伪装成系统进程文件（如 tiworker.exe）来劫持您的Windows安装。(Windows)虽然这在Windows 10(Windows 10)中很少发生，但它仍然可能发生，因此如果您的系统被感染，您可能不会意识到非正版进程正在运行，直到为时已晚无法防止损坏。
如果您看到CPU使用率较高的Windows Modules Installer Worker进程，并且您确信 Windows Update没有运行（即使在后台），那么这可能是由于非正版系统进程造成的。值得庆幸的是，检查您 PC 上运行的 tiworker.exe 服务是否为正版非常容易。
- 为此，您需要打开Windows 任务管理器(Windows Task Manager)。右键单击任务栏以执行此操作，然后选择任务管理器(Task Manager )选项。
- 在Task Manager窗口中，打开Processes选项卡并查找Windows Modules Installer Worker（或在Details选项卡中(Details )查找 tiworker.exe(tiworker.exe )）。右键单击该进程，然后选择打开文件位置(Open file location)选项。
- 这会将Windows 文件资源管理器打开到运行(Windows File Explorer)tiworker.exe文件的位置。如果该文件是真正的系统进程，这将在C:\Windows\WinSxS 目录的子文件夹中找到该文件。
如果Windows 文件资源管理器(Windows File Explorer)在任何其他位置打开，则您 PC 上运行的进程不太可能是真正的Windows 更新(Windows Update)进程。如果是这种情况，您需要使用 Windows Defender或使用第三方反恶意软件来安排防病毒扫描。(schedule an antivirus scan using Windows Defender)
防止恶意 Windows 进程(Protecting Against Rogue Windows Processes)
Windows Modules Installer Worker进程只是您不时在Windows 任务管理器(Windows Task Manager)中看到的许多重要的真正系统进程之一。没有它们， Windows(Windows)就无法运行，因为它们充当了将整个系统连接在一起的齿轮，从yourphone.exe等基本进程到系统内核本身。
当然，如果您确实在 PC 上发现伪装成系统进程的恶意服务，则需要尽早停止并运行恶意软件扫描。(run a malware scan)虽然很少见，但恶意软件可以并且将会通过附加或替换系统进程来隐藏自己。如果一切都失败了，您可能需要擦除并重新安装 Windows(wipe and reinstall Windows)来解决它。
What Is Windows Modules Installer Worker (and Is It Safe)
As one of the many system processes on your Windows PC, the Windows Modulеs Installer Worker playѕ a critical part in how Windows operates. You may not know it yet, but this procesѕ helps to ensure that the Windows Update service works correctly. Just like ntoskrnl.exe and others, you can’t stop or disable it.
That doesn’t mean that you shouldn’t take an interest in what exactly the Windows Modules Installer Worker process does and whether it’s safe, especially if you see it with high CPU usage in Task Manager. To help you, here’s what you need to know about this important process, including how to troubleshoot it if problems appear.
What Is Windows Modules Installer Worker?
The Windows Modules Installer Worker (tiworker.exe) process is part of the Windows Update service that keeps your PC up-to-date. When Windows Update is scanning for, downloading, and installing updates on your PC, the Windows Modules Installer Worker process will be running.
The service will also run in the background when Windows boots up after an update, completing post-update configuration of your PC. Most of the time, you don’t need to pay much attention to tiworker.exe, as the process will run without you needing to do much (unless you’re installing updates manually).
Considering how important Windows Update is as a Windows component, it’s fair to say that the Windows Modules Installer Worker process is safe to run. Attempting to end the process if it’s running, or otherwise interfere with it in any way, can cause issues that may result in broken Windows updates.
It isn’t possible to disable the Windows Update service in Windows 10, including tiworker.exe. If you try to do so, it may have unintended side effects, including breaking other Windows processes or, in a worst-case scenario, stopping your PC from running.
What Causes Windows Modules Installer Worker High CPU Usage Issues?
Unlike other system processes, such as csrss.exe, it’s fair to say that you may need to expect high CPU usage from the Windows Modules Installer Worker process. The Windows Update service will use a lot of system resources, especially when a major update is being installed.
This is unavoidable, but the impact on your PC will depend on your available system resources. If a Windows update is being installed, it may be advisable to close other running apps and allow for the process to complete. This will ensure that the demands on your PC are lower.
Because tiworker.exe is only used by Windows while updates are being prepared or installed, then you can expect to trace any issues with CPU, RAM, or disk usage back to the Windows Update service.
Once Windows has finished updating, the Windows Modules Installer Worker process should return to normal or stop entirely until it’s required again. If it doesn’t, you’ll need to troubleshoot Windows Update to try and resolve the problem.
Troubleshooting Windows Update Issues
When Windows Update has issues, then you’ll see the Windows Modules Installer Worker process under strain in Task Manager. If this is the case, you can check the current status of Windows Update (and troubleshoot it further) from the Windows Settings menu.
- To check the current status of Windows Update, right-click the Start menu and select the Settings option. This will open the Windows Settings menu.
- In Windows Settings, select Update & Security > Windows Update. If any updates are in process (or if an update has failed to update), these will be listed under the Update Status section. You can check the status of previous updates by selecting the View update history option.
- If updates have failed (or if they won’t install), then you can use the Windows Troubleshooter to investigate the problem. In the Windows Settings menu, select Update & Security > Troubleshoot > Additional troubleshooters to access the Troubleshooter menu.
- In the Additional troubleshooters menu, select the Windows Update option to begin troubleshooting the Windows Update service (including the linked Windows Modules Installer Worker process), selecting the Run troubleshooter button to confirm.
- A separate Diagnostic Troubleshooting Wizard window will open, with the Windows Troubleshooter automatically scanning and checking Windows Update for issues. If it detects any, it will attempt to fix these automatically, or it’ll inform you about the next steps you can take to fix them.
- If you want to view detailed information about Windows Update, you can select the View detailed information option once the process is complete. This will give you a breakdown of the checks it completed, allowing you to pinpoint any potential issues with the service.
How to Check If Windows Modules Installer Worker is a Genuine System Process
In some cases, malware will try to hijack your Windows installation by pretending to be system process files like tiworker.exe. While this is a rare enough occurrence in Windows 10, it can still happen, so if your system is infected, you may not realize that non-genuine processes are running until it’s too late to prevent damage.
If you see the Windows Modules Installer Worker process with high CPU usage, and you’re confident that Windows Update isn’t running (even in the background), then this could be due to a non-genuine system process. Thankfully, it’s very easy to check whether the tiworker.exe service running on your PC is genuine or not.
- To do this, you’ll need to open Windows Task Manager. Right-click the taskbar to do this, then select the Task Manager option.
- In the Task Manager window, open the Processes tab and look for Windows Modules Installer Worker (or tiworker.exe in the Details tab instead). Right-click the process, then select the Open file location option.
- This will open Windows File Explorer to the location where the tiworker.exe file is running from. If the file is a genuine system process, this will locate the file in a subfolder in the C:\Windows\WinSxS directory.
If Windows File Explorer opens in any other location, then the process running on your PC is unlikely to be the genuine Windows Update process. If this is the case, you’ll need to schedule an antivirus scan using Windows Defender or by using third-party anti-malware software.
Protecting Against Rogue Windows Processes
The Windows Modules Installer Worker process is just one of many important, genuine system processes that you’ll see from time to time in the Windows Task Manager. Windows can’t run without them since they act as the cogs that bring the entire system together, from basic processes like yourphone.exe to the system kernel itself.
Of course, if you do find a rogue service on your PC pretending to be a system process, you’ll need to stop and run a malware scan at your earliest convenience. While rare, malware can and will act to hide itself by attaching or replacing system processes. If all else fails, you may have to wipe and reinstall Windows to solve it.
