    Things I have tried this far: I tried in safe mode, installing during a
    restart and installing manually. Upon looking at my update history, I have
    12 other failed security updates. I unistalled McAffee and installed Windos
    security essentials, cleaned my computer with CCleaner, ran Spybot, and
    defragged my computer.
    Then I tried the Run: sfc. scannow and nothing came up.
    I went directly to the link provided

    There were several other updates that failed security updates:

    I listed them in order thinking that maybe I should do the earliest one
    first, one by one manually. I can't download a single update. Please help
    if you can.

  2. What's the name of the McAfee application that was installed and was your
    subscription still current when you uninstalled it & then installed MSE?

    Did you download/run the McAfee removal tool prior to installing MSE?

    Has a(another) Norton or McAfee application /ever/ been installed on the
    computer (e.g., a free-trial version that came preinstalled when you bought

    It is a free McAfee supplied by my internet company Cox cable. It is free
    but I thought it was a full version, part of their Cox Security Suite. It
    was installed 10/28/2009 (saved and scanned the file before running it)
    version 2 (

    It was slowing my computer down and it actually let in a trojan
    (Win32/Obfuscator.CY) which was detected and removed by Microsoft Security
    Essentials installed 2/26/10. I uninstalled through the program and files
    area in Vista control panel.

    I then booted in safe mode with internet and did some more cleaning after
    updating. The Microsoft Security Essentials I first tried to update and it
    would not. The screen was red as well. I tried to activate it but it would
    not in safe mode. Then I had a 3 day battle with spybot detecting
    smitfraudfix and smitfraudfix detecting spybot.

  4. McAfee (and Norton) applications are notorious for not uninstalling (or
    upgrading) cleanly. See if getting rid of the McAfee leftovers resolves the

    1. Download the McAfee Consumer Products Removal Tool, saving it to your

    2. Close all open applications (i.e., anything with an icon on the taskbar).

    3. Right-click on the file you saved in #1 above and select Run as
    Administrator to run the utility. Don't TOUCH your keyboard until the run
    completes, then reboot.

    Comment #1: You should have run the removal tool before you installed MSE.

    Comment #2: I agree with your opinion of that McAfee Security Center
    freebie. It's a POS.

    I was able to download the 4 missing updates plus 3 others. There are only
    20 I could not install :). I'm wondering if there is a way to clean the list
    so that my update history is easier to look through. I sorted the updates by
    title but I'm thinking the other 20 may be already installed. Each time I
    try to install them, it says that it does not apply to my system.

  6. There are only 20 I could not install...

    20? You only mentioned 4 in your first post. Are they all security
    updates? What's the release date of the oldest security update and what's
    its KB number?

    Has KB978207 installed?

    After seeing that there were other updates had failed, I went through this
    list very carefully by sorting the list and clicking on each failed update.
    Most were from the date 10/13/2009. I went one by one, saving an update file
    for each missing update to a folder on my desktop. There have been so many
    failed attempts, it was quite a long list. It could be that they are
    installed. If I could put the update history list in excel, I'd be more
    confident that I caught them all. By sorting and manually writing down the
    ones that failed, this is the remaining list.


    When I run the files, it says it does not apply to my system. Just because
    I was curious, I tried reinstalling a couple of the successful updates and I
    get the same message.

    I'm installin KB978207 right now. It was not there.

  8. When I run the files, it says it does not apply to my system.

    Don't concern yourself with the list of updates that failed to install per
    the Update History section at Windows Update website, at least for now.

    Open Internet Explorer (only) to http://windowsupdate.microsoft.com | Select
    CUSTOM and scan | Install any Critical Security Updates offered (e.g.,

    NB: Please do NOT install IE8 if it isn't already installed (just hide it
    for now).

    But if IE8 or IE7 is installed and a Root Certificates update is listed in
    the Optional Software updates category on the left-hand side of the scan
    results window, install it to take full advantage of IE's enhanced security.

    If there are any critical security updates you cannot install, please give
    me their KB numbers.
    That does NOT bode well.

    I do not get that screen when I go there where I can search for critical or
    custom updates. It shows directions to go to my start button |all
    programs|windows update. I do not get the update screen like I ususally see
    in xp. I thought that was a Vista thing, do they look the same? My
    computer says all critical updates hae been made. It seems to be functioning
    fine but the updat list is inaccurate if so.

  10. Sorry, I should not have assumed you were running WinXP; then again, you
    never stated your Windows version either.

    As long as no updates are listed in 'Available updates' and none are found
    when you click on 'Check for updates,' all is well.
