    When trying to update my computer, I recieved this error message (subject).
    I have had this OS (pre-installed through Dell). Went to Update site Monthly
    (or bi-weekly), whenever I feel froggie to do so. I thought I could update
    my computer recently but came across this error message.

    It stated that "Files required to use Windows Update are no longer
    registered or installed on your computer. To continue"
    ....and then gave me an option to "Register or reinstall the files for me now
    (Recommended)"
    .... or Read more about the issue.

    I have Windows XP (home) with SP2 and all of the updates (definately through
    November 2005, if not December). I am just unsure how this message can come
    up and tell me this when I have all of the updates required and I have been
    loyal in updating. Does anyone know what is going on here?

    I am unclear in what you wrote.

  4. Windows Update v6 installs client controls when you vist the site. If they are missing or
    unregistered the site doesn't work properly. What you're being offered is a self repair option to
    re-register/repair the files.


    Did you select the option to register/reinstall the files for me now?


    If you did, and there was no change -

    then some users have reported that simply re-registering the MSXML3.DLL seems to fix the problem.
    1. Click Start.
    2. Choose Run.
    3. In the Run box, type: regsvr32 MSXML3.DLL
    Press okay

    If that hasn't helped you may need to re-registered some more files:

    1. Click Start.
    2. Choose Run.
    3. In the Run box, type (pressing okay after each one) :-

    net stop wuauserv

    Repeat for the following:
    regsvr32 wuapi.dll
    regsvr32 wups.dll
    regsvr32 wuaueng.dll
    regsvr32 wuaueng1.dll
    regsvr32 wucltui.dll
    regsvr32 wuweb.dll
    regsvr32 MSXML3.dll
    regsvr32 qmgr.dll
    regsvr32 qmgrprxy.dll
    regsvr32 jscript.dll

    net start wuauserv

    Yes, I have done the self re-register/repair the files selection, then I have
    tried your suggestion of the START - RUN- REGSVR for the whole way down, am
    I suppose to repeat this for more than once? also, shall I have my
    web-browser closed while attempting this? Is there any other suggestions?

    All I know is that I have followed your post the whole way down and still, I
    recieve the same problem. Thanks for the help so far ( as well as future
    help).

  7. Re-install Windows Update files

    http://download.windowsupdate.com/v6/windowsupdate/redist/standalone/WindowsUpdateAgent20-x86.exe

    Note If you have an x64-based computer, visit the following Microsoft Web site:
    http://download.windowsupdate.com/v6/windowsupdate/redist/standalone/WindowsUpdateAgent20-x64.exe

    Click Save in the File Download-Security Warning dialog box, and then select the location where you
    want to save the file.
    Double-click the file that you saved

    NB - A note from Torgeir Bakken [MVP]

    Note that if it says "Install is not needed since Windows Update Agent is already installed.", run
    the exe with the command line switch /wuforce, like this:
    WindowsUpdateAgent20-x86.exe /wuforce

    Close IE and then restart IE and try visiting the WU site again.

    This last one did work and helped fixed the problem. Prior to this fix, I
    was able to search for express updates but not the customized updates.
    Thanks for all of the help. I really appriciate it.
