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??

The failure is because of how they do the download and the not reading the instructions.

2019-09-14T07:19:50+00:00 If they just run the MCT they get the ISO and if they do a Clean Install all of the bad things are deleted as the drive is basically formatted ie wiped clean. If they are updating then those things are still there causing problems.
I don't understand what you are trying to say here, the error is reported by MCT when trying to format the USB device and the device is no longer recognized.
I finally just reproduced one case here with the USB Selective Suspend.

I think the antivirus is just one of the many causes for this problem.
It doesn't explain why several users report that just copying and running the MCT from the same USB device used to make the installation media fixes their case.
I wish I could reproduce the problem and isolate at least one of the different cases.
Unfortunately it never fails for me on 5 different machines with current windows 10 x64 pro version 1903.
The easiest workaround in to download the windows.iso and then create the USB or the DVD from the iso, but still it would be nice to know why MCT fails in so many different situations. :(
One interesting explanation that I saw for the case fixed by running the MCT directly from the same USB device where the installation media will be created is that it will prevent the USB Selective Suspend from happening because of inactivity.
Some users have reported that disabling the USB Selective Suspend takes care of that particular situation.
It may take quite a long time from the beginning of the download to the moment when MCT needs to access the USB device to format it and start copying over the files.
That is the point when MCT shows 50% of the progress after the download and the verification and that is the time when the error occurs. The behavior of USB Selective Suspend may be different in different machines and different USB hub drivers.
Windows 10 includes the USB selective suspend feature that lets you automatically put USB devices in a very low-power state when they're not actively in use.
