Error 80240016

    General discussion


    I have been enduring this error since 16/01/2008 when my last clean update "Security Update for Windows Vista (KB941644)" was installed. See notes & details below.

    Installation date: ‎16/‎01/‎2008 11:21 PM

    Installation status: Successful

    Update type: Important

    A security issue has been identified in TCPIP that could allow an attacker to compromise your Windows-based system and gain control over it. You can help protect your computer by installing this update from Microsoft. After you install this item, you may have to restart your computer.

    Help and Support:


    Every since then I have been unable to install ANY "Security Updates for Windows Vista", this has in turn slowed the operation of my computer. (Purchased in May 2007).


    I have sent comments to Window, I have posted Questions in many forums, but all the advice that I have recieved has not solved the problem.


    I do not have advance computer knowledge, BUT if anyone has any idea how I can fix it I would be greatly appreciated.


    Kind Regards,
