svchost 100% CPU-Usage after login

Discussion in 'Windows Update' started by Thomas Niedermeier, Nov 10, 2006.

  1. Hi,

    we have a problem with our 400 Windows-Clients. After booting an login
    for the first time on a day the machines freezes for 2 minutes with a
    100% CPU-Usage by svchost.exe. We found out by using Regmon that the
    svchost checks all updates of the machine in registry. So we think it
    has to do with WSUS. In the windowsupdate.log I see nothing special.

    Any Ideas?

    Greetings
    Thomas

  2. 1) Turn off automatic WU notifications to quell the svchost disturbance.
    2) Keep asking, this will be a big problem next week on download day and
    afterwards.
    3) Does the manual Windows Updates Site work for you, or does svchost go bonkers
    only at the WU site and prevent you from downloading WCU's?

    Try deleting the contents of this folder (or the folder itself) & reboot:

    C:\WINDOWS\SoftwareDistribution\DataStore

    If no joy, try deleting the contents of this folder (or the folder itself) &
    reboot:

    C:\WINDOWS\SoftwareDistribution

  4. I have been experiencing a similar problem to the OP and your advice
    has worked very satisfactorily here - many thanks :)

  5. Which will work if the Automatic Updates service is not running.
    Otherwise, the edb.log in DataStore is in use and one can not delete it.
    This applies if deleting the entire Software Distribution folder, also.

    Start > Run > type in

    net stop wuauserv
    Click OK

    This will stop the AU service.
    To restart it
    Start > Run > type in

    net start wuauserv
    Click OK

  7. Hi,

    thank you.

    I tried it. Now the CPU takes not all the time 100%, only 5 sec then it
    goes down and again 5 secs for 2-3 minutes. Process Explorer shows now
    that wuauclt.exe takes CPU time, previous only svchost.exe takes CPU
    time. But it takes much longer, because it has to generate the 24 MB
    database.edb. The second time I start "wuauclt /detectnow" it gets again
    100% CPU.

    Also tried a Hotfix http://support.microsoft.com/kb/916089/en-us, but it
    became not better.

    Greetings
    Thomas

    I just deleted this folder and things work again. Thank you for getting me out
    of hot water again! :)
