wmiprvse.exe eating up ~25% CPU on windows 7


  • Hi! I'm having trouble with the WmiPrvSE.exe process taking up high levels of CPU and making usage generally quite unbearable. I know there are other topics that are related on the forums but I don't know how to apply them to my situation. Could anyone help?

    As far as I know, I'm not running a Windows Server on my laptop (a HP dm4-1028tx) nor do I have Windows System Resource Manager running.

  • For what it's worth, if this helps anyone else - I've identified my real source of high CPU for wmiprvse.exe was "Intel(R) PROSet/Wireless Event Log" service. (part of wireless card driver from Intel)

    a couple of observations:

    1) restarting (not just stopping) the "Intel(R) PROSet/Wireless Event Log" service helps bring CPU down

    2) once I either connect to another SSID or sleep/wake-up my laptop, the WmiPrvSE goes high CPU.
