    How to reinstall failed Windows Updates?


    Today's Windows Defender update failed to get installed (with "Unknown Error"). I followed instructions to download and run Microsoft Fixit.
    After that, the next instruction was to reopen Windows Update and try to rerun the failed install. But Windows Update provided no facility for downloading the failed update and rerunning it - it said that the updates were up-to-date already!
    I tried to delete the failed update from the Update History app. But it is not possible to delete what was not installed.
    So how can I find the file or download it again and then reinstall?
    I am running Windows 7 x64 Pro SP1.

    Windows Update - Reset
    ...then manually check for updates again.
