    I must be doing something wrong because I always have the update fail with some BS error like this. What are the proper steps to run this tool?

    I download the tool to the desktop. I'm on an Admin account. I insert a 16GB thumb drive. I format it. I start the tool. I point it to the thumb drive. During the phase where the files are copied to the USB, I get some stupid error like this:

    Why are my steps not good enough? Where is the hole in my logic? Or is this tool just written poorly. I'd like to use stronger language here as I used to have to start it all over again and burn bandwidth trying this failed endeavor over and over.


    I've heard people make it work by running the tool FROM the USB. Why would that matter? I've tried to write files to the thumb drive just after the format and before running the tool to make sure I have successful writes. Doesn't help.


    As a workaround today, I left the error up for a bit. Tried to access the thumb drive and it said it needed to be formatted AGAIN! So I did. Then I just opened the C:\$Windows.~WS\Sources\Windows and copied the files to the drive by hand. Made the dang thing myself! WHO WRITES THIS STUFF??

    What causes 0x80042405-0xa001a error at 50% during creating Windows 10 Media on USB flash drive when running the Media Creation Tool? I have Windows 10 April 2018 Update and need to update the installation media.

    This seems to be a common error for some, MCT can be fickle when creating and writing to thumb drives. Sure you have, but ensure you are getting the correct version. Language, home/pro, and the bits.. 32-bit or 64-bit. If that fails again, choose the option to just create the ISO only, you can choose where to let Windows create it. Then use another common Thumb Creator to actually make the thumb drive, Rufus. It will handle all the formatting and creation for you.
