Windows 10 Media Creation Tool Error 0x80070456 – 0xA0019
on Windows

Hello. I tried to use the Windows 10 Media Creation Tool to create a bootable USB flash drive, but in vain. The file is successfully downloaded, but fails in the middle of the file transferring to the USB. Each time the process ends up with the following error message: “Something went wrong ... 0x80070456 - 0xA0019.”

“Something went wrong ... 0x80070456 - 0xA0019” is a Windows 10 Media Creation Tool[ref en-1] bug. The tool is a small program that can be used for downloading and executing Windows 10 ISO file, which can further be used for Windows 10 installation DVD or USB. Media Creation tool download does not require having a product key.
