    KB837286 = Error code 800F0900.

    Subject code says it all. Get this error when trying to install that update
    over WU, doesn't get past 0%.

    Not quite because there is NO KB837286.

    The above error would mean the OS is Vista or WS 2008 since they use
    Component Based Servicing.

    Then post the correct KB number and any other relevant information so
    that someone can assist you.

    Sorry, it was a typo. It's KB 937286

    No problem. There is not much to go on in regards to the error code.
    The MSKB,, recommends a *manual
    installation* of the updated Help files.

    Download and save the updated Help files.
    When the download completes, close all open programs and browsers.
    *RIGHT* click the download and choose 'Run as administrator'
    Approve the prompts and hopefully, it will install now.

    That doesn't seem to work either, manual installation fails. It doesn't say
    that I've already got the update, it just says "failed".

    Let's see if there is any information in Event Viewer that may provide a
    clue as to why the update failed to install.

    Go to Start > Run > type in the following and click OK or press Enter


    Applications and Services Log > Microsoft > Windows >
    WindowsUpdateClient > Operational

    Please post the contents of the .xml entry for the failed installation
    of KB937286.

    Just received the same error resulting from an attempt to manually install an
    unknown update. Below is my xml file.

    The cause of the installation failure *may* be caused by a corrupted
    edb.chk file [transaction log].

    I'm not 100% sure about where these transaction logs reside in Vista.

    First, try renaming the copy in

    *RIGHT* click edb.chk and choose 'Rename'
    Name it edb.old
    Now try to install the *manually* downloaded copy of KB937286

    * IF a message comes up that the file is being used, open the Services
    console and STOP the Windows Update service, then rename edb.chk

    Manage services in Windows Vista

    IF you've had to stop the WU service in order to rename edb.chk,
    suggest you also rename Tmp.edb to Tmp.old, also, while the service has
    been stopped.
    After renaming the above, Start the WU service. *

    If no joy, rename the copy of edb.chk in

    Try another manual installation of KB937286

    Did that get it installed ?

    Re: KB837286 = Error code 800F0900.

    Did you rename ALL the transaction logs in ALL the locations listed in
    the KB article ?
    If so, I repeat:

    If the system has a persistent online connection then the update is NOT

    Yep, tried both WINDOWS\system32\CatRoot2 and
    WINDOWS\SoftwareDistribution\DataStore\Logs. No go.

    I've tried everything, and I keep getting error 800f0900. How do I go about
    installing the update?

    Re: KB837286 = Error code 800F0900.

    I apparently got rid of the 800F0900 error on my Vista Home Basic by
    installing Microsoft's System Update Readiness Tool (KB947821) -
    'Description of the System Update Readiness Tool for Windows Vista, for
    Windows Server 2008, and for Windows 7'

    for months, many updates gave me that error, but after installing
    KB947821, SP2 installation succeeded at first try.
