svchost strange CPU high usage RRS feed

  • Question

  • Hi,

    I have a brand new win 7 32 bit, I noticed since a couple of days that it was slow. I opened Task manager and saw a process

    svchost       50% (continuous)       Host process for windows services

    I launched Process explorer from sysinternals but still no tools is displaying which service or what application is doing this. I stopped so many serivces, automatic update, firewall..........still this svchost sitting there shooting 50%.

    Even I tried killing it, no way it comes back right away

    Thanks for your help

  • Andre, I uploaded the file latency.etl to

    the IP Helper Service (providing IP6 over IP4) causes the high CPU usage.

    Try to update all network card drivers. Does it also occur when Norton Internet Security is not installed?

    If you don't need the service and updating the drivers doesn't fix it, run services.msc and disable the service.

  • When you hover the mouse over it in procexp, there's no tooltip that says the name of the service?  Turn on the column & option to verify images, and see if it verifies.  In performance monitor, I think you can see the name of the services.

    EDIT: I mean resource monitor, there's a button for it in task manager.

  • Hi,

    please make a xperf trace [1] to diagnostic the high CPU usage. Please upload the etl file to your SkyDrive [2] and post a link here.

    I'll take a look at it, maybe I can see more details.

  • Hey Andre, in the Disk Utilization by Process graph summary table, how do you tell which service each svchost.exe is?  There's no 'Display Name' column like in the cpu graphs. Eh, the Display Names are all grouped together anyway.

    N. B : Can somebody from MS let me know why I am not receiving alerts. I am subscribed to instant alerts but nothing is being alerted. This has happened 1 year back and it was fixed, it seems that it came back

  • I already replied to you. Read my other post.

    Have you set the correct email address to get the alert?

  • How did you know it was the IP Helper service, and not one of the other 14 services running in that svchost.exe?

    because the iphlpsvc.dll is the cause. And this DLL which is the IP Helper service. Look at the Stackwalk Summary Table.

  • Hi,

    I had the same problem with svchost.exe -k netsvcs Running high CPU usage. It was the IP helper Service.

    I managed to narrow it down to VMware workstation Network adapter, I just removed that Network from the virtual network editor.
