The Windows Management Instrumentation Provider, or how it appears in the Task Manager, WMI Provider Host, it’s just an “informer”: it gives data and information about your system to some applications and programs. This process rarely appears for a large amount of time and it will rarely uses a lot of CPU and disk resources. If you think something is wrong with this process, keep reading this article for further information.
What is WMI Provider Host?
This process is part of the operative system and it’s the communication way between programs or applications and all the necessary information required asked by them to the operative system. The WMI stands for “Windows Management Instrumentation”, and its file name is WmiPrvSE.exe. This process is a part of Windows and a large number of programs use it to learn things about your system that can’t be learned otherwise. The WMI Providers Host can be used for all the applications that are windows-based.
Why is this process running on my pc?
The WMI Provider Host runs every time a programs request information about your system. This can lead to a several runs of this process daily. If you see the WmiPrvSE.exe process running on the background, is most likely to be giving information to any program installed in your operative system.
The WMI Provider Host is using a lot of my CPU resources. What can I do?
The WMI Provider Host don’t use a lot of your CPU. If you see this process using a large amount of CPU resources, it may be a program requesting some info, and this task can’t take a lot of time to finish. But if you see the WMI Provider Host spiking your CPU usage for a long time, it may be failing.
One of the ways to fix a failing WMI Provider Host process is to restart it. You can do this in the Services window. You need to click on the Start Button and search for “Services”. Once there, look for the Windows Management Instrumentation service, right-click on it and select restart. You can also just restart your system in the Shutdown Menu. Both ways can help you if the process was stuck doing the same task over and over.
There are also known issues with some antivirus. Some users are reporting that the WMI Provider Host get stuck using more than 20% of the CPU, overheating laptops and slowing systems. The problem was a conflict between the WMI Provider and a particular program.
You can see what program is generating the conflict by accessing to the Event Viewer. This tool is part of windows and can give you some information about the event logs and some failures that the system find. Here you can see if a program is conflicting with the WMI Provider Host.
To open the event viewer, right-click on the Start Button and select “Event Viewer” if you have Windows 8 or Windows 10. If you are using Windows 7, you will need to click in the Star Button and type “Eventvwr.msc”
Go to Applications and Service Logs\Microsoft\Windows\WMI-Activity\Operational in the left panel. Look for recent errors to find the ID of the process that it’s giving you trouble. You can see the ID at the right of ClientProcessId. Once you identify the Id of the process that is generating a conflict with the WMI Provides Host, it’s time to look for its name.
Open the Task Manager by right-clicking in the task bar and selecting “Task Manager”. Once there, go to the Details tab and look for the PID column. If the process it’s still running, it will be there. Now, with all this information you can reinstall the program associated with this process or search for more information in the web.
