    CAPICOM UPDATE KB 931906

    Hi

    Another Windows Update peculiarity??? In addition to my recent post re
    having successfully downloaded and installed the same Update - KB943411 -
    on Jan 9 AND Feb 9 this year, now my wife's PC has the above SECURITY Update
    listed as IMPORTANT and installed successfully yesterday on her Vista Home
    Premium PC, and 12 new updates today.

    But whilst MY PC has the 12 from today, but NO Update KB 931906 listed
    yesterday or today and NO updates waiting to be downloaded. My Vista Home
    PRemium PC is UP to date with no new updates.

    Why would her PC have required this and not mine do you think?

    It IS listed on MS support page as a MAY 2007 Security Update.

    Again, IT is NOT listed on MY PC as an installed update, BUT WAS downloaded
    and installed on my wife's yesterday. Again, why not on mine? AND how/why
    did her PC all of a sudden, a few months after install, decide it needed
    this MAY 2007 update? Should I worry about my PC NOT having it?

    That is a really old update from May of 2007. Are you sure you don't have it?

    K931906 (MS07-028) is an update to the crypto API for Windows, addressing a
    remote code execution vulnerability. The oddity about the feature is that it
    isn't part of the base Windows product, and the prime file (capicom.dll) may
    be installed by any application (from Microsoft or a third-party vendor)
    that needs it, and might be placed in any folder. The patch puts the
    updated copy in a standard location and makes appropriate entries in the
    Registry.

    If you don't have the CAPICOM.DLL file on your system, you don't need the
    update. What can happen is that a computer doesn't need the patch when it
    was released in last May's "Patch Tuesday" fun, but at some later time the
    user might install an application that brings with it a downlevel copy of
    the DLL file...and thus triggers the need for MS07-028.

    Having said that, my experience with the patch is that its "am I needed?"
    logic isn't the best. if you install the patch it seems to do what it
    should, but the Microsoft-provided XML that drives the installation tests
    doesn't seem to always trigger installation when an unpatched version is
    present. (I've squawked this up the line, and received the expected
    response: none.)
