For some reason muirct.exe is aware of the opaque structure used by BeginUpdateResource, it access the filename field of the opaque structure during it's processing.
MS documentation for the muirct utility: https://docs.microsoft.com/en-us/windows/desktop/intl/resource-utilities
Sample execution: MUIRCT.EXE -c "ui.exe" -e "de-DE\ui.exe.mui"
