After Update to Windows 8.1 the svchost.exe consume 10% cpu in endless loop

    Question

  • Hello,

    i checked the problem with Process Explorer and Process Monitor from sysinternals.

    The svchost.exe creates thousands of registry reads to HKLM\System\CurrentControlSet\Control\Nls\CustomLocale per second.

    One of these services causing the infinite loop:

    I hope any one can help me.

  • Finally i found the Problem. It was the Intel(R) PROSet Monitoring Service.

    Does Not work correctly on Windows 8.1 now.

  • I have similiar problem.

    After update from 8 to 8.1 processor usage has increased to 10-20 percent when computer is idle.

    Most CPU resources is used by netsvcs. But always atleast 10% is used by something that is not listed in task manager or resource monitor.

    In task manager I see that CPU usage is about 40% but all processes uses only 10-20 percent.

    So probably that is some driver issue but I don't know which one, yet.

  • Try Process Explorer from TechNet. This tool can display all CPU usages.

    On my PC its only the svchost.exe

  • If i create a new String Value named virtualization with de-DE under CustomLocale, the loop request a virtualization.nlp file on system-drive.

  • I know now, it is the winmgmt service (WMI) that consume my 10% CPU, but why?

  • In my case the problem was with sdclt.exe - Windows Backup

    Task scheduler was starting "sdclt.exe" in the endless loop. Each instance of sdclt was running probably less than 1 second so that's why I do not see it in task manager.

    I remove this task and windows is like new :)

  • Had the same problem and root cause is not Intel PROSet Monitoring service according to me, but the fact that the Scheduled Task under 'Microsoft\Windows\WindowsBackup\ConfigNotification' starts the following process:

    %systemroot%\System32\sdclt.exe /CONFIGNOTIFICATION

    Workaround is to either remove or disable this task and reboot your system.

    Have already seen this on 2 systems.

  • Thanks for this!  This has been driving me nuts.  I tracked it down to the WMI service (under the svchost process).  I could stop WMI and see CPU usage go to normal, but then WMI was restarting on it's own... annoying.  And go back to 10% usage for that total svchost process.

    I'd stopped just about every other service on my machine but I hadn't stopped the PROSet service...didn't even occur to me that might be the problem, it's so random.

    Sure enough, stopped it and my svchost is back to normal.  I guess it was flooding WMI with something or another, so it wasn't obvious that was the culprit at first glance.

  • Discovered this couple of minutes ago. SCVHOST with 17~20% CPU Usage and Intel PROset with 5%. When I kill this process (not SCVHOST, Intel PRO...), the bug was fixed. So I sugest running services.msc and disable Intel(R) PROSet Monitoring Service.

  • Thanks very much for this recommendation.

    My PC had become slow as molasses even since I updated from Windows 8 to 8.1, with between 4 to 6 instances of Microsoft Windows Backup processes spawning and respawning and hogging resources.

    Your recommendation (to disable the Scheduled Task) has resolved this for me.
