Transmac is a Windows based application which helps to open DMG files and burn it into CD/DVD on Windows operating system. Apart from that, it can do many other things like flash drives, CD/DVD, etc. But primarily users prefer it for viewing or burning DMG files when your Mac becomes completely unbootable.
But keep one thing in mind, though you can view the DMG files on Windows to check out the contents it comprises, but you cannot install the applications compressed in DMG files on Windows environment.
