    Chuck, the problem I had with the 2nd machine (Dell laptop) did not get
    resolved as easily as the situation I described earlier. This time it seems
    resemble the situation you describe. I did finally get it fixed after many
    of searching and trying different approaches. Here is what I did:

    1) First I tried to let it run itself to health, which it did, but only
    until the next
    boot and then it started all over again.

    2) After it had cleared up on its own I decided to force a Windows Update
    cycle to see if that would trigger the problem again; it did, but I let it
    run. I
    didn't time it because I was doing other chores around the house, but about 2
    hours later I checked and the screen indicated that some update
    had been applied AND there was a message on the screen inviting me to
    download and install SP3.

    3) Since I had nothing to loose I did select to download and install SP3 (I
    snoozed my CA Antivirus program, as several people reported difficulties with
    SP3 conflicting with A/V and antispyware programs). To my amazement, it
    seemed to work. When I checked on the progress a while later, it was waiting
    at a screen which told me to restart the machine. I did so, but after the
    reboot, the same damn problem with 100% CPU was still with me.

    4) I spent another hour or so checking different forums and noted a growing
    number of posts relating to this issue. Some suggested that Microsoft was
    attempting to screen millions of PCs before forcing out the SP3 update via
    automatic update; I know that sounds like malcontents spinning a conspiracy
    theory, but it did make some sense. Clearly Microsoft did something via the
    update process to trigger the problem on my machine (and the laptop) - it had
    been running just fine until Wednesday morning. I looked at so many forums
    and posts that I can't say with certainty, but I believe I finally found
    that worked on the site. One poster said they had done many
    of the things I had already done, but they decided to delete the
    SoftwareDistribution folder in the Windows directory, and would post back
    later to provide an update.

    5) Although I was cautious, I decided to try that on the problematic laptop.
    stopped the windows update service (to release the folder), then I just
    renamed C:\Windows\SoftwareDistribution to
    C:\Windows\SoftwareDistributionX and then I rebooted the machine. For the
    first time in days it started normally, AND it seemed to be running quicker
    it had originally. Perhaps SP3 does make a difference. I checked the
    Windows directory and found a brand new SoftwareDistribution folder in
    addition to the original I had renamed. Anyway, since it seemed to be
    normally I decided to take a chance and run a Windows Update; it ran and
    found a few non-critical updates so I allowed it to download/install them.
    too worked normally so I ran it once more and it now found a critical update
    for Windows Media Player 11, which had been installed in the previous run.
    installed the update and the system seemed to be fine. I rebooted once more
    to make sure, and sure enough, everything appeared normal.

    That was a long story, but not nearly as long as the hours spent on finding a
    resolution between Friday and late Sunday evening. My overall conclusion is
    that this was no freak accident. Someone within Microsoft approved some
    process to go out via Windows Update [true reasons unknown] and that
    decision had unintended consequences for many people. Will Microsoft [if
    they monitor these posts] step up and come clean? Probably not, but it would
    sure as hell be refreshing.

    Good luck.

  2. Did the exclusions in CA make any difference? Didn't make a scrap of
    difference to me.

  3. Maybe you should begin your own thread?

  4. Why's that? It's exactly the same problem, but excluding the files from the
    realtime scanner didn't do the trick (just as other potential fixes haven't
    worked for other people.

    This seems to have worked so far - thank you

    Has the underlying problem been identified and resolved yet?

    Helenix, May 12, 2008
  6. Of course, those are file types that definitely should be scanned. :-(

    It may be more effective to uninstall CA altogether (for non-commercial use,
    Avast is a free alternative that I've been very happy with - although I haven't
    installed SP3 on my home machine yet) or to disable automatic updates until CA
    release a proper fix.

  7. Are you running CA AV? If so try excluding the files mentioned in previous
    posts and also stop the automatic updates service, then rename the
    windows\softwaredistibution folder to softwaredistibution.old, restart
    automatic updates service. This seems to be working for me so far. I had also
    applied the suggested patches without any luck.

    I had the same problem with CA Antivirus. They are aware of the problem and
    working on a fix. Not sure how long that will be though. Rather than disable
    real time scanning - as this is as good as not having a scanner in the first
    place - exclude the *.msi and *.msp files. This worked for me.

    Martin C, May 13, 2008
  9. I have now successfully fixed this on 3 PCs with CA without excluding any
    Start, run, CMD.
    net stop wuauserv
    then in my computer rename windows\softwaredistibution folder to
    go back to cmd prompt
    net start wuauserv

  10. QED: Why was this step necessary?

    PA Bear [MS MVP], May 14, 2008
  11. I'm not sure why it was necessary but it does seem to eliminate CA. It was
    originally your idea to remove the softwaredistribution folder - I just
    renamed it instead. The point is, it works with no change to CA AV.

    My institution also began to see this issue on all machines starting around
    5/8/2008. Please share information that relates to this rescent problem.
    DZTN, May 19, 2008
  13. Are your machines cloned?

    Do you run CA antivirus?

    Have you tried deleting the softwaredistribution folder on one of the affected

  14. I think im in the same boat here with a laptop which after an update on 19th
    May (WAU had been disabled since april time so hadnt run or been used) is now
    going 100% CPU usage during update scans.

    Its tied to another issue my machine is now experiencing, which happened on
    my last laptop after it too hit the 100% CPU during the update process when
    the problem first arose prior to Update agent 3.0 being released around a
    year ago. Both machines now keep hitting the disk every second even when
    nothing is running and im not using the machine, with periods of the machines
    fans kicking in even when Task Manager shows no apparent CPU usage. Any small
    spike in CPU usage also causes the fan to kick in where it used to wait a
    while unless it was 100% usage for a shorter period would cause it to kick
    in. For anyone interested my other post is -

    So im interested in any conclusions people come to.

    From posts in various groups across the net, and from personal experience, I
    think this problem has run it's course. It appears that starting on May 7th
    (give or take a day) the contents of the C:\Windows\SoftwareDistribution
    folder, the Windows Update service, and the CA AntiVirus real-time scanner
    (engine 31.4) collided.

    Excluding installer file types from A/V scans, or snoozing the A/V, or
    deleting/renaming the C:\Windows\SoftwareDistribution, OR a combination of
    these tricks did seem to resolve the issue. Then about a week after it all
    began, CA released engine 31.5 via their automatic update and life has
    returned back to whatever the hell is normal.

    P.S. Make sure you remove any exclusions for CA A/V that you may have
    implemented as a circumvention.

    I tend to agree. I don't seem to be having any more problems with CA in that
    respect any more.

    I too am having the exact same problem that Chuck is having. Applying the
    fixes to my system does not resolve the problem. It bothers me that all the
    tips I find on this problem are dated a year ago. Why has this problem come
    back? Why is Microsoft unable to fix this issue permanently?

    Did you have any luck with this. All of our xp machines have started doing
    this also - they all have Windows Update Agent to 3.0 and KB927891 installed,
    they have XP SP2 installed so tried updating to SP3 and still get same
    results. All research points to this being an old problem.

    Hello, I know this post is old but we started to have the exact same issue
    Chuck discribe and I am disapointed to se that their is not a resolution on
    this or that I have not found one yet. THis is an issue we are having on
    over 10 Windows XP PRO SP3 all up do date pc's . As soon as we disable
    Windows update all workes well. But in my opinion this is not a solution. It
    is a temporarely fix.

    Does anyone have this issue still and is their a resent solution we tried
    everything on this post and other post to no avail.

    Thank you
