The utility muirct.exe for some reason accesses the opaque
HANDLE that is returned by BeginUpdateResource, it assumes
a certain structure in which (on 32bit systems) there is a
pointer to the wide repesentation of the file name in offset
0x18.
Refer to: muirct!BldToolsEndUpdateResourceW called from
muirct!CopyChecksumToFile
Sample execution:
MUIRCT.EXE -c "ui.exe" -e "de-DE\ui.exe.mui"
