Then, locate the install.wim file in the ‘sources’ folder of Windows 11 ISO image and copy the file using the Ctrl + C shortcut. Alternatively you also can right – click on the file and select the ‘Copy’ option from the context menu.
Now, plug the bootable Windows 10 USB drive into your computer and open it in File Explorer. After that, open the ‘sources’ folder inside the Windows 10 USB drive.
