Troubleshooting: file copy fails when you install Windows 10 from USB

This can happen when the Windows image file is over the FAT32 file size limit of 4GB. When this happens:

Step 1: You copy everything except the Windows image file (sources\install.wim) to the USB drive (either drag and drop, or use this command, where D: is the mounted ISO and E: is the USB flash drive.)

robocopy D: E: /s /max:3800000000

Step 2: You split the Windows image file into smaller files, and put the smaller files onto the USB drive:

Dism /Split-Image /ImageFile:D:\sources\install.wim /SWMFile:E:\sources\install.swm /FileSize:3800

Note, Windows Setup automatically installs from this file, so long as you name it install.swm.

After you install Windows 10, you can use  Windows 10 Product Key to activate it
