svchost.exe slowing down my system terribly RRS feed

  • Question

  • svchost.exe slowing down my system terribly. I ran the Kapersky program and no virus files came up. I am getting desperate. I am ready to kill my computer. Why is this process such a hog and how can I stop it?

  • To find what is causing your computer to use more CPU than it normally does you need to run this. 


    Open a CMD prompt with administrative rights (right click it>run as admin) and run this command for 60 secs to capture the high cpu usage: 


    xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 256 -FileMode Circular && timeout -1 && xperf -d cpuusage.etl

    The trace will run and give you a warning then revert to a C:\ prompt

    The log will be in C:\windows\system32.  It should be called cpuusage.etl

    Please zip the file and upload it to skydrive (or another file sharing service) and put a link to it in your next post.

  • Hi,

    You can use Process Explorer to detect which process takes up high cpu or memory usage under svchost.exe. And then double click abnormal process. Under Thread tab, please check which thread is culprit, then suspend this thread.

  • On a number of systems, svchost.exe was using GB of "I/O Read Bytes" and "I/O Other Bytes" on Windows 7 Pro and Home systems by different manufacturers.  The problem was resolved by disabling Superfetch.
