Identifying language and version of Windows 10 install USB

If for some reason you can’t use dism utility to inspect wim/esd files, you can use this workaround.
On install USB there is a file
sources/install.esd or sources/install.wim

open it in any hex editor or general file viewer supporting large files. Switch to UTF16 little-endian encoding if supported in viewer. at the end of the file you will see identifying information in XML format:
