I would read http://www.makeuseof.com/answers/what-is-wmiprvse-exe-and-why-is-it-causing-high-cpu-usage/ and try what they wrote there.

I recently purchased a Gatway computer (yah, stupid thing to do) running Windows 8. I am connected to the Internet by DSL but even my wife is complaining that the internet runs slow.
I checked the performance figures and "WMI Provider Host" is using 40-60% of the CPU with a total CPU usage of all programs at 98-99%. I tried to rename the file WmiPrvSE.exe so that it would not run but I encountered a message that said that action would require a "trusted installer". I even attempted to boot to a flash drive or CD install of "Lucid Puppy" to do the rename under Linux but the BIOS will not allow any boot except to "Windows Boot Manager".
Any ideas or an I going to have a slow Internet forever?
