He’s looking for an executable program called "showhidecontrols_en.exe"
A thorough Google search will turn it up, probably at a Russian web site as the author was Russian IIRC.
It is referenced in the BH/WH14 thread as a way of forcing a crossflash of an unsupported drive.
It allows manipulation of the flasher program, while running in memory, to allow you to “push” buttons that are hidden and/or disabled.
