Our TAC support desk has seen some recent instances of HP notebooks having CPU usage spikes that drive overheating because the HP Wireless Assistant service gets hung up.
If, on an HP laptop, the WMIPrvSE.exe process is causing repeated excessive CPU usage spikes (25% or more every few minutes) and thus overheating, try disabling the HP Wireless Assistant service.
(Start menu -> Control Panel -> Administrative Tools -> Services)
Some older versions of this software have this issue, though HP indicates the latest version is fixed for this bug.
The HP Wireless Assistant's only purpose seems to be to inform the user whether the wireless is on or off. However, if you find your wireless switch on your keyboard no longer works with the HP Wireless Assistant disabled, obtain the latest version from HP's website, uninstall the old first, then install the new.
If you need more help with this issue or would like other help with your technical support issues, please don't hesitate to contact us in the Technical Assistance Center!
