Window 10 Media Creation Tool errors with 0x80070456 0xA0019


I am trying to use the Windows 10 Media Creation Tool to create a bootable USB flash drive but am getting an error message. It seems download the files successfully but fails part way through transferring the files to the USB drive.

The error message code I get is "Something went wrong ... 0x80070456 - 0xA0019"

The steps I take are

  1. Run the program
  2. Accept the license conditions
  3. Choose "Create installation media for another PC"
  4. Language "English (United States)", Edition "Windows 10", Architecture "64-bit (x64)"
  5. Choose "USB flash drive"
  6. Choose the USB flash drive from the list

I am running Windows 10 Professional. The USB drive is 64Gb.

The real problem is the the USB device's formatting type . You need a FAT32 USB not an NTFS one. Indeed all the USB greater than 32GB NEED an NTFS system and is quite normal that the procedure doesn't work with them. You have to change in any case the system format of the USB in FAT32. ;)

I've had this problem, it seems that media creation tool will fail if the partition type is GPT even if the usb drive is formatted fat32 and the space is sufficient. Convert your usb drive to mbr and format it again as fat32 and it will work

The answer for me was to use a smaller USB drive. It worked successfully on an 8Gb USB flash drive.

I had searched for answers on the internet and it seems like everyone who was having similar problems were using USB drives greater than 32Gb.

Hope this helps someone.

If reformatting the USB drive does not work, try switching the USB-drive to another USB port on your computer. Doing this resolved this issue for me.

The media creation tool is full of bugs.

Just use it to create an iso (for a DVD install), then use Rufus or a similar tool to create a bootable USB flash drive from the iso.

check that the antivirus does not block some program process like "autorun.inf" If this occurs, it will momentarily deactivate the antivirus or the real-time protection of the antivirus
