    Once you type the command line, go to Windows Update and you will see it downloading automatically.

    I tried deleting everything in the download folder specified by OP, i also even tried deleting files in "$Windows.~BT" that i saw in another how to site... nothing worked. i tried 3 times already. first it said it was downloading just over 2.7gb, next it was nearly 6gb i presume because i deleted more this time. regardless this solution does not work for me. anybody have any idea why, or how to fix it?

    I can't delete all the folders in C:\Windows\SoftwareDistribution
    Ok, you are in the wrong location..... Go back to this statement........::
    1. Go to C:\Windows\SoftwareDistribution\Download and delete all files in that folder only the files in download folder
    not the download folder !

    the way to get to the actual folder, click start and paste that C location in to the search or run box, which ever you have. and hit enter. Next, up in the search window click that folder. Now you can delete everything. Then go back to the next directive which will be about the Command Prompt. The rest works fine. My windows 10 is downloading now.... 7:20PM 07-30-2015

    Method 2 I just found this solution from Microsoft :)

    Source : Windows Update Installation Failure 80240020 - Microsoft Community

    P.s Do this method if you know what your are doing

    1st method downloaded it , but still failed after downloading it again.
    2nd method after the download fixed it..

    Now saying preparing for installation.. Hope it goes all the way through..

    I tried method 1 but after a lot of downloading, I ended up getting the same error code. Method 2 creating the AllowOSUpgrade in the registry did work for me.
