修复服务主机：本地系统 (svchost.exe) 高 CPU 和磁盘使用率：^{(Fix Service Host: Local System (svchost.exe) High CPU and Disk Usage:)}如果您遇到此问题，其中名为服务主机^{(Service Host)}：本地系统^(System)(svchost.exe) 的进程正在使用所有系统资源，导致CPU和磁盘^(Disk)使用率高在任务管理器^{(Task Manager)}中然后不要担心，因为今天我们将在本文的帮助下看到如何^(How)解决此问题。如果您因服务主机^{(Service Host)}：本地系统^(System)进程而面临高 CPU^{(High CPU)}使用率、内存^(Memory)使用率或磁盘使用率，这篇文章将有所帮助。^(Disk)

什么是服务主机：本地系统 (svchost.exe)？^{(What is Service Host: Local System (svchost.exe)?)}

服务主机^{(Service Host)}：本地系统^(System)本身就是在其下运行的其他系统进程的捆绑包，换句话说，它基本上是一个通用的服务托管容器。因此，解决此问题变得困难，因为在Service Host^{(Service Host)} : Local System下运行的任何进程都可能导致CPU或磁盘使用率过高问题。服务主机^{(Service Host)}：本地系统^(System)包括用户管理器、组策略客户端^{(Group Policy Client)}、Windows 自动更新^{(Windows Auto Update)}、后台智能传输服务^{(Background Intelligent Transfer Service)}( BITS )、任务计划程序^{(Task Scheduler)}等进程。

可以快速看到Service Host : Local System 下的各种进程，同时按Ctrl + Alt + Del打开任务管理器^{(Task Manager)}，然后切换到Processes选项卡，找到Service Host相关进程，如Service Host : Local Service , Service Host : Network服务^{(Network Service)}等。当您扩展这些服务时，您会发现其下运行着各种进程。

如您所见，有许多进程在服务主机^{(Service Host)}下运行：本地系统^(System)(svchost.exe)，例如Windows 更新^{(Windows Update)}，这可能会占用大量系统资源，但如果某个特定进程不断导致CPU和磁盘^(Disk)使用率很高，那么它可能是一个需要注意的问题。因此，不要浪费任何时间，让我们在下面列出的教程的帮助下看看如何修复服务主机^{(Fix Service Host)}：本地系统^(System)(svchost.exe)高 CPU^{(High CPU)}和磁盘使用率。^{(Disk Usage)}
