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.

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.
