Even though it runs in the background of your Windows, the WMI Provider Host is still an essential part of your software. Its main job is to allow other apps to ask you for information about your system.
However, if you have other misbehaving processes on your computer, the WMI Provider Host might start using too much of your CPU.
What Is It?
WMI, short for Windows Management Instrumentation, is a feature that allows other processes to request information about your Windows system. It will give out information when prompted.
For example, it can access entries on your event log, or inspect your BitLocker drive encryption. If you are interested, you can go to Microsoft’s website and look through the list of WMI providers.
This feature is useful even if you have a home PC. Moreover, enterprises often use it to request information from their centrally managed computers. You can even use it to find certain data on your computer, like the serial number or the motherboard’s model number.
CPU Usage Issue
Using way too much CPU is not what your WMI Provider Host should be doing. It is normal to use some of it if a script on your computer is asking for certain information. Nevertheless, if it’s using a significant amount of CPU, that usually means that another app is requesting information through it. But, that should happen only occasionally.
You can try to fix this issue by restarting the Windows Management Instrumentation service:
- Type “Services.msc” in the Search bar and open the Services tool.
- Find “Windows Management Instrumentation” and restart it (right-click on it).
If the WMI Provider Host is using too much CPU, then you probably have a misbehaving process on your computer. You can identify it by following these steps:
- Right-click the Start button and find “Event Viewer” (Windows 8/10)
- If you have Windows 7, you can type “Eventvwr.msc” in the Search bar.
- When you open it, find “Applications and Service \Logs\Microsoft\Windows\WMI-Activity\Operational”
- It will list out “Error” events, but you should only look for the recent ones. When you click on each one, you will see an ID number of the misbehaving process. You will find it on the right of “ClientProcessId”
You will probably find a few errors, but different processes might be causing them. When you locate the misbehaving process, you can then pin it down:
- Open Task Manager. You can use the shortcut “Ctrl+Shift+Escape,” or you can right-click the Taskbar and find it in the list.
- Open the “Details” tab and sort the processes by clicking on the “PID” column.
- Find the misbehaving process by matching its ID number to the listed one.
However, bear in mind that you will not find the process if it has since closed. Furthermore, it is vital to look through the recent error events because the ID number changes when you reopen the process.
Now that you have found it, you can search for it on the web and see what it actually does. You can also open its File Location and locate its larger software package. In order to fix the issue, you will have to uninstall it or update it.
Should I Disable The WMI Provider Host?
You can disable this service, but it will lead to a number of different issues. It’s a vital part of the OS, so you should just leave it as it is. Otherwise, other parts of the software will not function properly.
