    Default Windows 10 Cumulative Update KB3194798 fails to install

    Few users are reporting that the just released Cumulative Update KB3194798 is failing to install on their Windows 10 computers with a with Failed to complete installing updates, Undoing changes message.

    I've tried to process this update a few times through Windows Update, but it fails each time, uninstalls, and puts things back where they were, says a user on Microsoft Answers.
    KB3194798 is a security update and hence important that it be installed.

    If you are facing this Windows 10 update problem, the only thing I can suggets for the moment is to clear the contents of the SoftwareDistributin folder, disable your antivirus software and then try to install the updae again.

    In some of the cases, it seems that the installation issues experienced with KB3194798 are caused by the operating system failing to download and decompress the update, so manually downloading the patch could help address the bugs.

    For the moment, however, there’s still no confirmation that this works for everybody, but we’ve received messages from users saying that manually downloading the cumulative updated did the job not only in this case but also with other botched patches released in the past.

    So if you want to give this method a try, here are the download links for KB3194798 x86 and KB3194798 x64 - make sure you download the version that’s appropriate for your computer.
