This post shows you how to troubleshoot WmiPrvSE. Windows Management Instrumentation Provider Service or WMI Provider Host High CPU Usage issue. Greetings, There is a process which is using up all my CPU CWindowsSystem32wbemWmiPrvSE. I see that its in the wbem subfolder. Does that. Why does WMI Provider Host Wmi. Prv. SE. exe keep spiking my CPU As Sathya mentioned in his question, I have had previous experience with this problem on my similar HP laptop, and I have now confirmed using the scientific method that the CPU spikes on HP laptops is caused by the HP Wireless Assistant. Or, HP CPU Assassin, as I may start calling it. Overview of the Experiment. Question What is causing the CPU on HP laptops to spike at frequent intervals, specifically the. Wmi. Prv. SE. exeprocess Hypothesis The HP Wireless Assistant HPWA is causing the problem. Method See if the problem starts occurring when the HPWA is installed. See if the CPU stops spiking and the Wmi. Prv. SE. exe process stops using 2. Aiml Tools there. CPU when the HPWA process is suspended. See if the CPU starts spiking again when the HPWA process is re enabled. Repeat steps 2 and 3 for multiple trials to ensure accurate of results.

Conclusion You should uninstall HPWA as it does nothing useful. Background information. When I got my HP Pavillion dm. I noticed that the CPU would frequently spike to as much as 5. This was draining battery life, and heating up the laptop much the same symptoms as Sathya has experienced. Just by looking at the Resource Monitor in Windows 7, I was able to see that the process Wmi. Prv. SE. exe was at fault. A quick google search confirmed my assumption that this was the Windows Management Instrumentation WMI host process. In short, WMI can be used to query for system information, like processor usage, running processes, who is logged on, and all sorts of other information. The WMI host process runs WMI queries for any other process making them, so Wmi. Prv. SE. exe was not itself the culprit, it was simply an intermediary. In order to hunt down which specific process was causing this problem, I used Systinternals Process Explorer. I found which instance of the Wmi. Prv. SE. exe process was using a large amount of CPU, and clicked on it to open detailed information. Unfortunately, I couldnt see any way to find out what process was making all the queries, but since I had isolated this as the source of the CPU spikes, and knew it was a service, I went to the services manager to see which services depended on WMI, thinking that might lead me to another clue. I figured that it wouldnt be a built in Windows service causing the problem, so eliminating those, I decided to work down the list and try disabling each service, and seeing if the problem persisted. Right on top of the list was the HP Wireless Assistant Service. I went back to the services menu, and disabled that service. Looking back in the task manager, I saw that CPU usage had gone to almost nothing. I the HPWA service back on. CPU usage shot back up. I now had enough data to form my theory. I uninstalled the HPWA service, and never had the problem again. Verifying the Hypothesis. Several months later, Sathya asks this question. I decided to prove once and for all that this was HPWAs fault. I reinstalled the HP Wireless Assistant, which I hadnt had installed in months. Right away, processor usage shot up. I then went through with the experiment outlined above. First, I isolated the process responsible for the HPWA service in the Resource Monitor. HPWAService. exe and HPWAMain. Here is what the CPU usage looked like with both of these processed running Then, I suspended both processes. The CPU usage immediately went down heres what it looked like after a few moments for the previous CPU usage on the graph to clear I enabled the processes again to see if usage would go back up. It did The first spike as I enable HPWAA little while after I enabled HPWASuspending the processes again resulted in the CPU usage going back down I tested this for one more iteration, and on the third trial, the same exact thing happened again. I considered this sufficient evidence to show that the HP Wireless Assistant was causing the problem, and subsequently disabled the service, and will now uninstall it. All the HPWA appears to do is inform the user when their wireless is turned on or off, and gobble CPU. There is nothing you can do with it that you cant do with the built in wireless management tools, so I would advise that if you have this software installed, you remove it. Activar Windows Xp Sp3 Bloqueado. Note At least one person has reported that uninstalling HPWA caused their wireless switch on the keyboard to stop working. On my laptop, it kept working fine after uninstalling HPWA, but in case yours does stop working, you can always disable the wireless card from inside Windows. Press x to open the Windows Mobility Center, then click on the Turn Wireless Off button. According to a discussion on the HP Support Forums, the problem has been fixed in more recent versions of the HP Wireless Assistant. If your laptop needs HPWA to use the wifi onoff button, you can download the latest version from HPs drivers website, and probably wont have this problem any more. Nevertheless, if you dont need it for the wifi onoff button, there still seems to be no added value from having this software installed.
