Diskimgwriter is a command line tool to be run on Windows to write whole disk images, like an RPi image consisting of multiple partitions, to a removable disk drive like a USB thumb drive or an SD card.
It also works if the disk drive already contains multiple partitions, i.e. got multiple drive letters (volumes) assigned to it by the operating system, which appears to be a problem with other image writers that offer a choice based on drive letters.
Diskimgwriter can be run by entering
diskimgwriter file.img
in a command interpreter window,
or by dragging file.img onto diskimgwriter's icon.
The program, as configured by a setting in the manifest file,
will request adminstrator privileges to get access to the physical drive.
A UAC consent promp will show up that needs to be confirmed with yes.
A console window will open, presenting a menu for selecting a disk drive, and giving information about progress:
