If your WMI Provider Host is recording high CPU usage, you are not the only one having the issue. It is something that a number of other users of Windows 10 have also experienced. Although this can be inconvenient, the WMI Provider Host service has a role to play. Also known as the WmiPrvSE or Windows Management Instrumentation Provider Service, it is used by Developers for Monitoring Purposes. It serves to allow other programs to communicate with the computer.

If the service fails to run, therefore, these services may also experience some problems. In fact, your applications may fail to run as they ought to and you may not even be notified of this. The problem with the service is that because of some errors, it sometimes puts a lot of load on the CPU thereby limiting the performance of the computer which may sometimes lead to the freezing of the system.

Some of the problems that can be caused by high CPU usage by either this service or others may include slow performance and programs finding it hard to start, overheating of CPU, excessive lag, freezing of computer, unresponsive program, and the screen turning blue (blue screen of death) among others.

Since disabling the program is not something you want to do, here are some very easy ways that you can fix it yourself. Before then, it is worth noting that the WMI Provider Host should consume just between 1% and 2% of the CPU. Nevertheless, you may record as high as 50% to even 90% when it has the problem of high CPU usage. In order to know the performance of the WMI Provider Host and the CPU resources it is using, simply go to your Task Bar (Control + ALT + Delete and select Task Manager). Then find WMI Provider Host. Beside it, you will see the percentage of CPU that it is using.
