Windows 10 具有多个内置工具，可帮助自动分析和修复系统中的损坏文件。一种这样的工具是DISM或部署映像服务(Deployment Image Servicing)和管理(Management)。它是一个命令行工具，可帮助在Windows 恢复环境(Windows Recovery Environment)、Windows 安装程序(Windows Setup)和Windows PE上维护和准备(Windows PE)Windows映像。当系统文件检查器(System File Checker)无法正常工作时， DISM也可以在这些情况下工作。但是，有时您可能会遇到DISM主机服务进程高CPU 使用率(CPU Usage)错误。本文将讨论什么是DISM主机服务过程是以及如何解决高CPU使用率问题。读到(Read)最后！
如何修复 DISM 主机服务进程高 CPU 使用率问题
(How to Fix DISM Host Servicing Process High CPU Usage Issue
)
什么是 DISM 主机服务流程？(What is DISM Host Servicing Process?)
尽管DISM(DISM)主机服务过程具有各种优势，但也存在许多与DismHost.exe相关的冲突。许多用户声称它是Windows 操作系统(Windows Operating)的重要组成部分。但是，有些人不同意这种说法，因为您在任务栏上看不到它的图标(Taskbar)。另一方面，一些防病毒应用程序将其视为恶意软件。因此(Hence)，DISM主机服务过程会导致各种问题，例如：
- 高达 90% 到 100% 的高 CPU 使用率
- 恶意软件威胁
- 高带宽消耗

阅读(Read)并实施给定的解决方案，以修复导致Windows 10上(Windows 10)CPU 使用率过高(High CPU Usage)问题的DISM 主机服务进程(DISM Host Servicing Process)。
方法 1：重启你的电脑
(Method 1: Restart Your PC
)
在尝试其余方法之前，建议您重新启动系统。在大多数情况下，简单的重启即可解决问题，无需付出太多努力。
1. 按Windows键并选择电源(Power)图标
注意：电源图标在(Note:)Windows 10系统中位于底部，而在Windows 8系统中位于顶部。
2. 会显示几个选项，如睡眠(Sleep)、关机(Shut down)和重启(Restart)。在这里，单击Restart，如图所示。
重新启动系统将刷新RAM并降低CPU消耗。
方法 2：禁用 SuperFetch (SysMain)(Method 2: Disable SuperFetch (SysMain))
名为SysMain(SysMain)（以前称为SuperFetch）的内置功能改进了应用程序和Windows的启动时间。然而，系统程序并没有从中受益太多。相反，后台活动增加，导致计算机的运行速度降低。这些Windows服务会消耗大量CPU资源，因此通常建议在您的系统中禁用 SuperFetch 。(disable SuperFetch)
1. 同时按住Windows + R键启动运行(Run)对话框。
2.如图所示， 键入 services.msc ，然后单击(services.msc )确定(OK )以启动服务(Services)窗口。
3. 现在，向下滚动并右键单击SysMain。然后，选择Properties，如图所示。
4.在这里，在常规(General )选项卡中，从下拉菜单中将启动类型(Startup type )设置为已禁用，如下所示。(Disabled )
5. 最后，单击应用(Apply)，然后单击确定(OK )以保存更改。

This articlе wіll discuss what is DISM host servicing process is and how to fix high CPU usage issues. Read till the end!
How to Fix DISM Host Servicing Process High CPU Usage Issue
What is DISM Host Servicing Process?
Despite the various advantages of the DISM host servicing process, there are many conflicts associated with DismHost.exe as well. Many users claim that it is an essential component of the Windows Operating system. However, some people do not agree with this claim as you cannot see its icon on the Taskbar. On the other hand, some antivirus applications consider it malware. Hence, the DISM host servicing process leads to various issues like:
- High CPU usage up to 90 to 100%
- Malware threat
- High bandwidth consumption
Read more about DISM here from the Microsoft website.
Read and implement the given solutions to fix DISM Host Servicing Process causing the High CPU Usage issue on Windows 10.
