如果您正面临Windows Modules Installer Worker的^{(Windows Modules Installer Worker)}高 CPU 使用率^{(High CPU Usage)}，请不要担心，因为成千上万的其他用户也面临着类似的问题，因此，我们今天将在本文中讨论许多有效的修复程序。要验证您是否遇到此问题，请打开任务管理器^{(Task Manager)}( Ctrl + Shift + Esc )，您会发现Windows Modules Installer Worker正在消耗高 CPU^{(High CPU)}或磁盘使用率^{(Disk Usage)}。

专业提示：^{(Pro Tip:)}Windows完成下载和安装更新后，您可以让您的 PC 过夜或几个小时以查看问题自行纠正。

什么是 Windows 模块安装程序工作者 (WMIW)？^{(What is Windows Modules Installer worker (WMIW)?)}

Windows Modules Installer worker ( WMIW ) 是一项负责自动安装Windows Update的服务。根据其服务描述，  WMIW是一个系统进程，可以自动安装、修改和删除Windows更新和可选组件。

此过程负责自动查找新的Windows 更新^{(Windows Update)}并安装它们。您可能知道 Windows 10 通过Windows Updates自动安装较新的版本（即 1803 等） ，因此此过程负责在后台安装这些更新。

虽然这个进程被称为Windows Modules Installer worker ( WMIW )，并且你会在任务管理器的^{(Task Manager)}进程^(Processes)选项卡中看到相同的名称，但是如果你切换到详细信息^(Details)选项卡，那么你会发现文件的名称为TiWorker.exe。

为什么Windows Modules Installer worker使用^(Using)这么多CPU？

由于Windows Modules Installer worker ( TiWorker.exe ) 在后台连续运行，有时它在安装或卸载Windows 更新时可能会占用较高的^{(Windows Updates)}CPU或磁盘使用率。但是，如果它经常使用高CPU，那么Windows 模块安装程序^{(Windows Modules Installer)}工作人员在检查新更新时可能会变得无响应。因此，您可能会遇到延迟，或者您的系统可能会完全挂起或冻结。

用户遇到系统冻结或滞后问题时要做的第一件事是重新启动他们的 PC，但我向您保证，这种策略在这种情况下不起作用。这是因为除非您解决根本原因，否则该问题不会自行解决。

修复 Windows Modules Installer Worker 高 CPU 使用率^{(Fix Windows Modules Installer Worker High CPU Usage)}

确保 创建一个还原点^{(create a restore point)} 以防万一出现问题。

Windows Modules Installer Worker ( WMIW ) 是一项重要的服务，不应禁用它。WMIW或TiWorker.exe不是病毒或恶意软件，您不能只从 PC 中删除此服务。因此，不要浪费任何时间，让我们在下面列出的故障排除指南的帮助下查看如何修复 Windows 模块安装程序工作人员高 CPU 使用率。^{(How to Fix Windows Modules Installer Worker High CPU Usage)}

Fix Windows Modules Installer Worker High CPU Usage

If уоu are facing the High CPU Usagе by Windows Modules Installer Worker, thеn don’t worry аs thousands of other users are alѕo facing the similar problem and therefore, there are many working fixes which we will be discussing today in this article. To verify if you are facing this issue open Task Manager (Ctrl + Shift + Esc) and you will find that the Windows Modules Installer Worker is consuming High CPU or Disk Usage.

Pro Tip: You may leave your PC overnight or for a few hours to see the issue rectify itself once the Windows is finished downloading and installing updates.

What is Windows Modules Installer worker (WMIW)?

Windows Modules Installer worker (WMIW) is a service which takes cares of automatically installing Windows Update. According to its service description, WMIW is a system process that enables automatic installation, modification, and removal of Windows updates and optional components.

This process is responsible for finding new Windows Update automatically and installing them. As you might be aware that Windows 10 automatically install newer builds (i.e. 1803 etc.) via Windows Updates, so this process is responsible for installing these updates in the background.

Although this process is called Windows Modules Installer worker (WMIW) and you will see the same name in the Processes tab in the Task Manager, but if you switch to Details tab, then you will find the name of the file as TiWorker.exe.

Why Is Windows Modules Installer worker Using So Much CPU?

As Windows Modules Installer worker (TiWorker.exe) runs continuously in the background, sometimes it might utilize high CPU or disk usage when installing or uninstalling Windows Updates. But if its constantly using high CPU then the Windows Modules Installer worker may have become unresponsive while checking new updates. As a result, you may be experiencing lags, or your system might hang or freeze completely.

The first thing users do when they experience freezing, or lagging issues on their system is to restart their PC, but I assure you that this strategy won’t work in this case. This is because the issue will not resolve by itself until and unless you fix the underlying cause.
