Windows 11/10/8/7的一个常见问题是无法解释的高磁盘使用率^{(High Disk usage)}，它有时会冻结系统的所有其他进程。在很多情况下，在检查任务管理器^{(Task Manager)}时，会发现Windows Modules Installer Worker CPU 和磁盘使用率非常高^{(CPU and Disk Usage is very high)}  - 有时甚至超过 50%！

什么是 Windows Modules Installer Worker？

Windows Modules Installer Worker或WMIW或TiWorker.exe检查来自Windows服务器的新更新并将它们安装在您的计算机系统上。此过程可能会导致系统负载，在某些情况下，会将磁盘使用率推至 100%，从而挂起或冻结所有其他进程。重新启动系统将不起作用，并且问题不会自行解决。

Windows Modules Installer Worker 高 CPU^{(Modules Installer Worker High CPU)}或高磁盘使用率^{(High Disk Usage)}

如果Windows Modules Installer Worker在Windows 11/10中显示高 CPU^{(High CPU)}和磁盘使用率^{(Disk Usage)}，请尝试以下建议：

1. 检查计划的自动维护^{(Automatic Maintenance)}是否正在运行
2. 检查 Windows 更新是否正在运行
3. 使用 AV 扫描您的 PC
4. 杀死 TiWorker.exe 进程
5. 运行 Windows 更新疑难解答
6. 运行 SFC 和 DISM
7. 禁用自动 Windows 更新

让我们详细看看这些方法。

1]检查^(Check)计划的自动维护^{(Automatic Maintenance)}是否正在运行

在开始之前，您需要检查您的Windows是否正在运行计划的自动维护任务，如果是，请给它一些时间（可能是几个小时）来完成。您将在此处看到其设置 -Control Panel > All Control Panel Items > Security和Maintenance > Automatic Maintenance。

2]检查^(Check)Windows Update是否正在运行

如果Windows 更新^{(Windows Update)}正在运行，使用率也可能会很高——所以请给它一些时间。如果它没有运行，则运行Windows Update并查看是否有可用的并安装它们。

3]用AV扫描你的电脑

您可能还想扫描您的计算机以查找恶意软件。所以运行防病毒扫描。

4]杀死TiWorker.exe

完成此操作后，您可以尝试的下一件事是在任务管理器本身^{(Task Manager)}中终止 TiWorker.exe 进程^{(kill the TiWorker.exe process)}并重新启动它，看看它是否有帮助。但问题很可能会不断重复出现。因此，必须停止相关服务。

5]运行Windows更新疑难解答^{(Run Windows Update Troubleshooter)}

运行Windows 更新疑难解答，看看它是否对您有帮助。

6]运行SFC和DISM

运行系统文件检查器和DISM 工具^{(DISM Tool)}来替换损坏的系统文件并修复损坏的系统映像。

7]禁用自动Windows更新

如果没有任何帮助，您可能想查看是否要禁用自动 Windows 更新^{(disable automatic Windows Update)}。如果您决定这样做，请打开服务管理器^{(Services Manager)}。这可以通过按Win+R运行^(Run)框然后运行命令services.msc来完成。

将设置更改为“检查更新，但让我选择是否下载并安装它们^{(Check for updates but let me choose whether to download and install them)}”。

Windows 11/10用户可能需要参考这篇文章来禁用自动 Windows 更新^{(disable Automatic Windows Update)}。

^(Reboot)完成上述步骤后重新启动系统。上述过程将“Windows 更新”设置为手动^(Manual)模式。因此，它不会自动检查更新，只有在您命令它时才会检查。这是一种解决方法，直到您能够找到解决方案。

也许启动到干净启动状态^{(Clean Boot State)}将帮助您进一步解决问题。请记住每周手动检查和更新您的计算机，以防您选择遵循最后的建议。

Windows Modules Installer Worker (TiWorker.exe) High CPU & Disk Usage

A frequently encountered issue with Windows 11/10/8/7 is the unexplained High Disk usage which at times freezes all other processes of the system. In a lot of cases, upon checking the Task Manager, it is found that the Windows Modules Installer Worker CPU and Disk Usage is very high  – at times even more than 50%!

What is Windows Modules Installer Worker?

The Windows Modules Installer Worker or WMIW or TiWorker.exe checks for new updates from the Windows server and installs them on your computer system. This process might cause load on the system and in some cases, push the disk usage to 100%, thus hanging or freezing all other processes. Restarting the system won’t work, and the issue does not resolve by itself.

Windows Modules Installer Worker High CPU or High Disk Usage

If the Windows Modules Installer Worker is showing High CPU & Disk Usage in Windows 11/10, try the following suggestions:

1. Check if Scheduled Automatic Maintenance is running
2. Check if Windows Update is running
3. Scan your PC with AV
4. Kill TiWorker.exe process
5. Run Windows Update Troubleshooter
6. Run SFC and DISM
7. Disable automatic Windows Update

Let us take a look at these methods in detail.

1] Check if Scheduled Automatic Maintenance is running

Before you begin, you need to check if your Windows is running the Scheduled Automatic Maintenance task and if it is, then give it some time – maybe hours, to finish. You will see its settings here – Control Panel > All Control Panel Items > Security and Maintenance > Automatic Maintenance.

2] Check if Windows Update is running

The usage may also go high if Windows Update is running – so give it some time. If it is not running then run Windows Updates and see if any are available and install them.

3] Scan your PC with AV

You might want to also scan your computer for malware. So run an antivirus scan.

4] Kill TiWorker.exe

Having done this, the next thing you can try is to kill the TiWorker.exe process in the Task Manager itself and restart it and see if it helps. But it is quite likely that the problem will keep recurring. Thus, the concerned service has to be stopped.

5] Run Windows Update Troubleshooter

Run the Windows Update Troubleshooter and see if it helps you.

6] Run SFC and DISM

Run the System File Checker and DISM Tool to replace corrupted system files and fix a corrupted system image.

7] Disable automatic Windows Update

If nothing helps, you may want to see if you want to disable automatic Windows Update. If you do decide to, open the Services Manager. This can be done by opening the Run box by pressing the Win+R keys and then running the command services.msc.

Change the setting to ‘Check for updates but let me choose whether to download and install them‘.

Windows 11/10 users may need to refer to this post to disable Automatic Windows Update.

Reboot the system after completing the procedure above. The procedure above sets the ‘Windows Update’ to the Manual mode. Thus, it will not check for updates automatically and only when you command it to. This is a workaround till you are able to find the solution.

Perhaps booting into Clean Boot State will help you troubleshoot the issue further. Do remember to check for and update your computer manually every week, in case you choose to follow the last suggestion.
