    After reviewing half a dozen posts where so-called MCPs, MCIEs and every
    yahoo on the net is suggesting that wuauclt.exe is spyware or a worm I
    figured I'd
    save everyone the trouble.

    Couldn't care less who Jeff Wells is and I ceratinly don't plan my day
    around his likes and dislikes.

    You're welcome.

  3. Chris,

    Did you happen to see Susan Bradley's post ? :

    The Automatic Updates service may stop responding:

    My laptop showed 98% CPU useage yesterday and if it persists, I'll be
    asking for the Hot Fix from the KB ;)

    p.s. WU drives me to drink ... often !

    Dumb more like it! - have you no idea how many groups there are in Microsoft
    NGs - and you think MS should monitor them all.
    That has to be the joke of the week :)

    Oh ok, thanks Jupiter.

    It does make sense that they might just have a little peek

    So you don't think big brother is even taking a sneaky peek!! Get out of
    this mans sand pit he need somewhere to put his head!!!!!

    Excuse me this site is on an msnews server and is called

    Doh... You dont think that one person in the Windows Update Team couldnt
    review this "TARGETED" site to get a feel for whats going on out there in
    the users world.

    I realise there is a mountain of extraneous gum flapping goes on here as 80%
    will testify to, so I can see the poor MS employee might see the task as the
    worst part of his/her day. However I would imagine someone may think it
    sensible to scan it now and again. (see Jupiter Jones post)

    Yes I did.

    Unfortunately my problem is not one of memory usage but cpu hogging, like
    yours appears to be. Also the update process does not stop responding, far
    from it, it actually response so well it hogs the whole machine. So I don't
    think the hotfix mentioned on that KB article will actually solve our
    problem. However if you want to get it from MS I would definitely like to
    know if it makes a positive difference to our problem.

    The general consensus, for what that's worth, appears to be that the new
    update code has something in it that causes older/slower processors
    problems. Microsoft know about a similar problem but have not put a date on
    a fix, or even said they will fix it. They do quote it as a problem related
    to WSUS which is a little worrying, in case they don't know its killing a
    lot of us general users too.


    In fact having read the page above again, more carefully, the problem
    documented is far worse than the one I am experiencing and quite possibly
    not directly related. I am therefore not really any better off regarding a
    solution or knowing whether MS know about our little problem.

    I think I will just take a walk to the water-cooler and have a chat until my
    PC will let me in again.

    On the 2nd Tuesday of every month, Microsoft releases updates which are
    automatically applied to millions and millions of computers worldwide. Hey, if I
    were the one coding a patch, I'd be a just a little nervous about screwing up.

    So you're saying that it's beneath Microsoft to stop by here once in a while and
    see if they caused any problems with their updates?!?!?!?


    I tried to resolve the SVCHOST 100% CPU issue through the Windows Update support
    team. Now they're passing the buck. This is what they wrote:

    Thank you for contacting Microsoft Online Customer Service.

    After reviewing the information you have provided us it appears this is a system
    issue rather than Windows Update issue which should be handled by our
    Professional Support team. Please contact our Professional Support Team at the
    following toll free number:

    800-936-4900 available 24 hours

    Based on the current situation, I will close this case as Not Resolved. When
    contacting the Professional Support team please reference this case number and
    they will re-open the case if appropriate. I would also like to assure you that
    you will not be charged for this case since Windows Update issues are supported
    free of charge.

    I appreciate your patience in this regard and trust they will be able resolve
    this issue in a timely fashion.

    Microsoft know about a similar problem but have not put a date on
    Mine was configured for WSUS and locked up ( 100% CPU svchost-wuaclt )
    whenever the automatic update process started its detect cycle. But
    it also locked up when I tried to do a manual update on the Microsoft
    update web site too.

    It had all updates, including root certificates, and AV was turned off.
    Uninstalling Windows Defender made the symptoms go away and its worked
    fine the past several weeks.

    Essex male - I recognised the name from many years back and wondered - in
    connection with the forensic medicine lab in London - Prof Cameron.
    Your father was a Police Surgeon I seem to recall - there is a health centre
    I believe named after your father down in the south-west corner of Essex.
    Did you follow in your father into the medical profession?
    Small world they say.

    I just did my third fresh install of XP Pro SP1 on a Armada M600 with a P3
    600mhz with 320mb ram and 12 gig hd. On the first install of XP Pro SP1 I
    continues and installed SP2 and that is when the svchost went to 98% cpu
    usage and stayed. On the second install I went to WU and it had me download
    the new WU program. That is when my svchost went to 98% cpu usage and stayed.
    On this, the third install I am leaving it at SP1 and Automatic Updates
    didn't promp me to update. So I have disabled AU in the System Properties.

    I plan to wait unitl MS fixes the problem and hope that it will be on the
    second Tuesday of October.

    What am I risking by doing this?

    Hello Mow
    As you are one of the leading fixers/problem solvers in the updates group, I
    am indeed upset to read that you have problems.
    Well, if you can't fix this problem I fail to see who can.
    Has this Black Tuesday started off worse than last month - its difficult to
    tell :-(
    I wish success and look forward to your continued support and help.

    I did much the same as you - but disconnected from the net after getting
    into WU Home page to get the KB numbers(took nearly ten minutes for the
    little 'green train' to stop) - then I got each KB from its respective site
    and saved to disc.
    Things were a bit slow on the MS site - some pages took a minute or two to
    But so far........:)

  17. "So you're saying..."
    never said anything like that.

    What I did say "Microsoft occasionally comes to these peer to peer
    So obviously is not "beneath" them.

    Please do not change the meaning of what I wrote.

    Yes I believe he was and there is. Mother divorced him when I was 2 so
    cannott claim any knowledge or connections or great family links.

    No medical connections, I went into IT believe it or not. Prof Cameron? Is
    that you?

  19. Howdy Antioch,

    Well, whatever the issue was, it's gone now. While it was occurring I
    ran Process Explorer to see what proccesses and threads svchost.exe
    was using. Nothing unusual showed up.
    This was while impending updates were still in the download phase, i.e.
    notification of the updates appeared and I approved them.
    Due to "regulation" - 2006-09-13 11:00:29 472 4c4 DnldMgr * Update is
    not allowed to download due to regulation

    the system had to wait another day to actually do the download phase.
    When the ones approved were installed and the system restarted, the
    issue went away.

    Hard to draw a definitive conclusion, but it appeared to be an issue
    with the AU service when it was "waiting" for the downloads to actually
    come down. YMMV, of course ;)

  20. Jupiter is correct and if one checks the NG one can see that there IS
    someone from MS who has been responding to issues posted.

    But, we still need someone from MS (remember Lucy Eby ?) who regularly
    participates in the newgroup and communicates with the MVPs ... don't
    we, Jupiter ? ;)
