    Update for Windows 10 Version 1511 for x64-based Systems (KB3122947) failed to install. I ran check for updates, it said my system was up to date.

    Looking at update history, there are only 2 updates listed, where are all the other updates?

    Windows 10 update system sucks, give me the old manual update system.

    :)

  2. Windows 10 failed install, failed to revert to previous OS

    Thank you for the reply.

    The PC is an Acer all in one but I'm unable to remember/locate the model.

    Prior to attempting the upgrade we did unplug all devices except for the mouse and keyboard. We had Avast installed for antivirus but we made sure that we disabled this before upgrading.

    We get no error messages, but when trying various ways to try and fix the issue I did receive a message saying that OS Loader could not be found

    Hi Leon,

    Thank you for posting your query in Microsoft Community.

    I understand the inconvenience you are facing currently.

    I would appreciate if you can provide us the following information to help us understand the issue better.

    • What is the make and model of the computer?

    • Do you have any third party security program installed on the PC?

    • Do you get any error code or error messages?

    As of now, I suggest you to disconnect all the external devices (printers, scanner, USB (universal serial bus) drives, etc...) Except mouse and the keyboard and then boot up.

    If this corrects the issue then add the devices back one at a time until you discover the piece of hardware causing the issue.

    Please get back to us with a reply so that we can assist you further.
