大多数Windows(Windows)用户并不熟悉WMI Provider Host之类的进程，但这并不意味着它们对操作系统不是必需的。在这种情况下，与csrss.exe(csrss.exe)等其他关键进程一样，WMI 提供程序主机(WMI Provider Host)不应该是您需要考虑的事情，除非它会导致CPU或RAM使用率过高。
WMI Provider Host进程通常不会引起关注，因为没有它，Windows将(Windows)无法正常工作。但是，如果 wmiprvse.exe 有问题，则可能表明存在更深层次的问题，例如恶意软件感染(malware infection)。以下是您需要了解的有关Windows 10中(Windows 10)WMI Provider Host进程的所有信息。
什么是 Windows 10 中的 WMI 提供程序主机？(What Is WMI Provider Host in Windows 10?)
WMI (Windows Management Instrumentation) Provider Host进程充当信息中继，向各种正在运行的软件和请求它的系统服务提供有关Windows当前如何运行的信息。
这些请求由负责提供特定系统信息位的WMI 提供程序处理。(WMI Providers)例如，如果另一个服务需要访问Windows事件日志，那么这将由Event Log Provider 提供(Event Log Provider)。
WMI 提供程序(Providers)也不限于Windows服务。可以使用WMI(WMI) 提供程序(Providers)创建第三方应用程序和服务，这些提供程序可用于向其他应用程序和服务提供信息。这种管理系统很有用，尤其是在您负责大量Windows设备的情况下。
链的顶端是WMI 提供程序主机(WMI Provider Host)(wmiprvse.exe)。这是控制每个WMI 提供程序(WMI Providers)的过程。没有它，Windows可能会停止工作，因为其他服务使用WMI 提供程序(WMI Providers)发布的数据来确保Windows正常运行。
WMI Provider Host 安全吗？可以禁用它吗？(Is WMI Provider Host Safe and Can It Be Disabled?)
虽然对您不熟悉的Windows(Windows)进程感到好奇是很自然的，但您可以高枕无忧，因为WMI Provider Host对(WMI Provider Host)Windows来说是一个完全安全的进程，应该保持运行。
事实上，任何禁用WMI Provider Host进程的尝试都可能导致意想不到的后果。像这样的重要系统进程并非偶然出现——它们的运行是为了帮助Windows保持全面运行。特别是，WMI 提供程序主机(WMI Provider Host)向其他进程提供详细的系统信息。
如果没有此信息，您的 PC 可能会认为发生了严重的系统故障。这可能会导致“关键进程死亡”蓝屏(“critical process died” BSOD)错误，立即使您的 PC 崩溃并停止工作。
如果该过程导致问题，则可能是由于另一个应用程序或服务与之交互，您可以停止或禁用它。考虑到这一点，答案很明确：WMI Provider Host 不能(can’t)被禁用，您不应该尝试这样做。
唯一的例外是当另一个进程不是真正的进程时，它被命名为(real)WMI Provider Host。已知某些类型的恶意软件会模仿重要的进程，试图在快速浏览Windows 任务管理器(Windows Task Manager)时欺骗用户。
值得庆幸的是，有一种简单的方法可以测试是否是这种情况，正如我们在下面的一节中解释的那样。
如何解决 WMI 提供程序主机高 CPU 问题(How to Troubleshoot WMI Provider Host High CPU Issues)
在正常的 PC 使用过程中，很少会看到WMI Provider Host出现高CPU问题。大多数时候，wmiprvse.exe 进程处于休眠状态，准备处理信息请求。
如果您发现CPU使用率出现峰值，这可能是由于从(CPU)WMI 提供程序(WMI Provider)请求信息到另一个应用程序或服务。如果您在较旧、速度较慢的 PC 上运行Windows ，这可能是不可避免的，但如果WMI Provider Host长时间报告CPU使用率很高，那么您需要进一步调查。(CPU)
您可以从事件查看器(Event Viewer)检查哪些进程正在使用WMI 提供程序主机(WMI Provider Host)服务，其中记录了来自 WMI 提供程序的错误和警告报告。使用此信息，您可以跟踪导致WMI 提供程序主机(WMI Provider Host)使用比正常情况更高的CPU使用率的其他应用程序或服务。(CPU)
- 为此，请右键单击“开始(Start)”菜单并选择“运行”(Run)选项。在“运行”(Run)窗口中，键入eventvwr.msc，然后选择“确定(OK)”打开。
- 在Event Viewer窗口中，使用左侧导航菜单打开Applications and Services Logs\Microsoft\Windows\WMI-Activity\Operational。在中间部分，搜索可能指向某个进程的最近事件（标记为Error ）。选择记录的错误，然后找到ClientProcessId编号，该编号列在下面信息部分的“常规(General )”选项卡下。
- 使用ClientProcessID编号，您可以通过打开(ClientProcessID)Windows 任务管理器(Windows Task Manager)找到导致问题的匹配进程。右键单击(Right-click)底部的任务栏，然后选择任务管理器(Task Manager)来执行此操作。
- 在任务管理器(Task Manager)窗口中，打开详细信息(Details)选项卡，然后从事件查看器中找到具有与ClientProcessID匹配的(ClientProcessID )PID号的条目。
找到导致WMI 提供程序主机(WMI Provider Host)问题的进程后，您可以尝试结束、禁用或卸载它。如果它是另一个Windows系统进程，那么您可能需要通过修复损坏的系统文件来进一步解决您的(repairing corrupt system files)Windows安装问题。
检查 WMI 提供程序主机是否合法(Checking Whether WMI Provider Host Is Legitimate)
您将在Windows 任务管理器(Windows Task Manager)中看到的WMI 提供程序主机(WMI Provider Host)进程是一个Windows系统进程——或者它应该是。您可以通过跟踪进程的文件位置来检查是否是这种情况（以及病毒或其他类型的恶意软件是否隐藏在普通视图中）。
- 为此，请通过右键单击窗口底部的任务栏并从菜单中选择任务管理器选项来打开(Task Manager)Windows 任务管理器。(Windows Task Manager)
- 在任务管理器(Task Manager)窗口中，在进程选项卡中找到(Processes)WMI 提供程序主机(WMI Provider Host)进程（或在详细信息选项卡中找到(Details)wmiprvse.exe）。右键单击该进程，然后选择打开文件位置(Open file location)选项。
- 这将启动Windows 文件资源管理器(Windows File Explorer)，打开WMI Provider主机可执行文件的位置。这应该在C:\Windows\System32\wbem 文件夹中找到。如果是，那么在您的 PC 上运行的进程就是合法的Windows系统进程。
如果您发现在文件资源管理器中打开了另一个位置，那么您就有问题了，因为您在(File Explorer)Windows 任务管理器(Windows Task Manager)中看到的正在运行的进程不是(not)合法的系统进程。作为后续步骤的一部分，您需要搜索并清除恶意软件(get rid of the malware)，以确保您的 PC 可以安全使用。
了解 Windows 系统进程(Understanding Windows System Processes)
WMI Provider Host系统进程只是保持Windows安装工作的数百个隐藏可执行文件之一。(hidden executable files)它不能被禁用，如果您尝试删除或停止它，Windows可能会崩溃，如果您之后无法正常工作，您可能需要擦除并重新安装 Windows 。(wipe and reinstall Windows)
具有高CPU问题的系统进程（例如 wmiprvse.exe 和dwm.exe）通常指向您的 PC 的其他维护问题，从尘土飞扬的 PC 风扇(dusty PC fans)到恶意软件感染。如果Windows 任务管理器(Windows Task Manager)中的某个进程看起来不熟悉，那么这并不意味着您需要扫描恶意软件(scan for malware)，尽管这样做不会造成任何伤害。
What Is WMI Provider Host (and Is It Safe)
Processes like thе WMI Provider Host aren’t well known to most Wіndows users, but that doesn’t mеаn that they’re not essential to the operating systеm. In this case, and like other сritical рrocesses such as csrss.exe, the WMI Provider Host shouldn’t be something you need to think about, unless it causes high CPU or RAM usage.
The WMI Provider Host process shouldn’t usually cause concern, as without it, Windows won’t work properly. If wmiprvse.exe has problems, however, then that could point to deeper issues, such as a malware infection. Here’s everything you need to know about the WMI Provider Host process in Windows 10.
What Is WMI Provider Host in Windows 10?
The WMI (Windows Management Instrumentation) Provider Host process acts as an information relay, offering information on how Windows is currently running to various running software and system services that request it.
These requests are handled by WMI Providers that are responsible for giving out specific bits of system information. For instance, if another service requires access to the Windows event log, then this would be provided by the Event Log Provider.
WMI Providers aren’t limited to Windows services, either. Third-party apps and services can be created with WMI Providers that can be used to provide information to other apps and services. This kind of management system can be useful, especially if you’re responsible for a large number of Windows devices.
At the top of the chain is the WMI Provider Host (wmiprvse.exe). This is the process that controls each of these WMI Providers. Without it, Windows will likely stop working, as the data issued by WMI Providers is used by other services to ensure Windows is running properly.
Is WMI Provider Host Safe and Can It Be Disabled?
While it’s natural to be curious about Windows processes that you aren’t familiar with, you can rest easy, as WMI Provider Host is an entirely safe process for Windows and should be left running.
In fact, any attempt to disable the WMI Provider Host process could result in unintended consequences. Vital system processes like these aren’t there by accident—they’re running to help Windows remain fully operational. In particular, the WMI Provider Host provides detailed system information to other processes.
Without this information, your PC may assume that a critical system failure has occurred. This could cause a “critical process died” BSOD error that immediately crashes your PC and stops it from working.
If the process is causing issues, it’s likely due to another app or service interacting with it, which you may be able to stop or disable instead. With this in mind, the answer is clear: WMI Provider Host can’t be disabled and you shouldn’t try to do so.
The only exception to this is if another process is named WMI Provider Host when it isn’t the real process. Some types of malware have been known to mimic important processes, in an attempt to fool users during a quick glance at Windows Task Manager.
Thankfully, there’s an easy way to test if this is the case, as we explain in a section below.
How to Troubleshoot WMI Provider Host High CPU Issues
During normal PC usage, it’s unusual for there to see WMI Provider Host with high CPU issues. Most of the time, the wmiprvse.exe process sits dormant, ready to process requests for information.
If you spot a spike in CPU usage, this could be due to a request for information from a WMI Provider to another app or service. This may be unavoidable if you’re running Windows on an older, slower PC, but if WMI Provider Host reports high CPU usage for a long period of time, then this is something you’ll need to investigate further.
You can check which processes are using the WMI Provider Host service from the Event Viewer, where error and warning reports from WMI Providers are recorded. Using this information, you can trace the other app or service causing the WMI Provider Host to use a higher CPU usage than normal.
- To do this, right-click the Start menu and select the Run option. In the Run window, type eventvwr.msc, then select OK to open.
- In the Event Viewer window, use the left-hand navigation menu to open Applications and Services Logs\Microsoft\Windows\WMI-Activity\Operational. In the middle section, search for recent events (labelled Error) that could point to a process. Select a logged error, then find the ClientProcessId number, listed under the General tab in the information section below.
- Using the ClientProcessID number, you can find the matching process causing issues by opening Windows Task Manager. Right-click the taskbar at the bottom and select Task Manager to do this.
- In the Task Manager window, open the Details tab, then find the entry with a PID number that matches the ClientProcessID from the Event Viewer.
Once you’ve found the process causing WMI Provider Host issues, you can attempt to end, disable, or uninstall it. If it’s another Windows system process, then you may need to look at troubleshooting your Windows installation further by repairing corrupt system files, for instance.
Checking Whether WMI Provider Host Is Legitimate
The WMI Provider Host process you’ll see in Windows Task Manager is a Windows system process—or it should be. You can check whether this is the case (and if a virus or other type of malware is hiding in plain view) by tracing the file location of the process.
- To do this, open Windows Task Manager by right-clicking the taskbar at the bottom of your window and selecting the Task Manager option from the menu.
- In the Task Manager window, find the WMI Provider Host process in the Processes tab (or wmiprvse.exe in the Details tab). Right-click the process, then select the Open file location option.
- This will launch Windows File Explorer, opening the location of the WMI Provider host executable file. This should be found in the C:\Windows\System32\wbem folder. If it is, then the process running on your PC is the legitimate Windows system process.
If you find that another location opens in File Explorer, then you have a problem, as the process you see running in Windows Task Manager is not the legitimate system process. You’ll need to search for and get rid of the malware as part of your next steps to ensure that your PC is safe to use.
Understanding Windows System Processes
The WMI Provider Host system process is just one of hundreds of hidden executable files that keep your Windows installation working. It can’t be disabled, and if you try to remove or stop it, Windows may crash, and you may need to wipe and reinstall Windows if you can’t get things working afterwards.
System processes with high CPU issues, like wmiprvse.exe and dwm.exe, often point to other maintenance issues with your PC, from dusty PC fans to a malware infection. If a process in Windows Task Manager seems unfamiliar, then it doesn’t mean that you need to scan for malware, although it won’t do any harm to do so.
