The host process of the WMI provider is an important part of Windows and often runs in background. It allows other applications on your computer to request information about your system. This process shouldn't normally use many system resources, but it can use a lot of CPU if another processof your system is behaving badly.
RELATED: BitLocker Drive Encryption , view event log entries, or request data from installed applications that include a WMI provider. Microsoft has a list of WMI providers on his website. .
This is a particularly useful feature for companies that centrally manage PCs, especially since information can be requested via s and displayed as standard in consoles. administrative. However, even on a personal computer, some software that you have installed may request information about the system through the WMI interface.
You can also use WMI yourself to find a variety of useful information that is not normally exposed in the Windows interface on your own PC. For example, we have couvert the WMI command line tool (WMIC) to get your PC serial number , find your motherboard model number , or just to view the SMART health status of a hard drive .
Why does it use so much CPU?
The WMI provider host should not normally use a lot of CPU, becausehe shouldn't normally do anything. It can sometimes use processor when other software or on your PC requests information via WMI, and this is normal. High CPU usage is probably just a sign that another application is requesting data via WMI.
However, prolonged CPU usage is a sign that something is wrong. The WMI provider host should not use a lot of CPU resources all the time.
Restarting the Windows Management Instrumentation service can be useful if it is frozen in a bad state. You can also restart your computer, but there is a way to restart the service without restarting your computer. To do this, open your Start menu, type "Services.msc " and press Enter to launch the Services tool.
Locate the "Windows Management Instrumentation service "in the list, right click on it and select " Restart ".
If you notice high and constant CPU usage, it is likely that another process on your system is behaving badly. If a process constantly requests a large amount of information from WMI providers, the WMI provider's host process will use a lot of CPU. This other process is the problem.
To identify which specific process is causing problems with WMI, use the Event Viewer . In Windows 10 or 8, you can right-click on the Start button and select "Event Viewer " to open it. In Windows 7, open the Start menu, type "Eventvwr. msc "and press Enter for the lancer.
In the left pane of the Event Viewer window, go to à Microsoft Windows applications and service logs WMI-Activity Oper ational.
Browse the list and look for recent events "Error ". Click on each event and look for the number to the right of "ClientProcessId in the lower pane. This tells you the number of Identification of the process that caused the WMI error.
Chances are you will see multiple errors here. The errors can be caused by the same process ID number, or you can see several different process IDs causing errors. Click on each error and see what ClientProcessId should discover.
You can now identify a process that may be causing problems. First, open a Task Manager window by pressing Ctrl + Shift + Esc or by right-clicking on the taskbar and selecting "Task Manager " .
Click on the "Details" tab, click on the "PID" column to sort the running processes by process ID and find the process corresponding to the ID number that appeared in the logs of the Event Viewer.
For example, here we have seen that the process "HPWMISVC.exe caused these errors on this particular computer.
If the process has been closed since then, you will not see itnot in the list here. In addition, when a program closes and reopens, it will have a different process identification number. This is why you should search for recent events, as the process ID number of older events in your Event Viewer will not help you find anything.
With this information in hand, you canNow start the process that can cause problems. You can search for its name on the Web to find out which software it is associated with. You can also right-click the process in the list and click "Open file location to open its location on your system, which may show you the biggest software package that the program is part of. You may need to update this software if you are using it or uninstall it if you are not.
Can I deactivate the host of the WMI provider?
It is technically possible to deactivate the "Windows Management Instrumentation service on your computer. However, it will break a lot of different things on your PC. This is an important part of the Windows operating system and should be left alone.
As the official deion for this service indicates, "If this service is stopped, most Wind softwareows won't work properly ". So don't disable this service! If you have a problem, you need to identify the process on your computer that causes the WMI provider host to use so much CPU and update, delete or disable this process instead.
