[GTALUG] "dd" in Windows?

Hi all, How do you write "image" file to USB stick in Windows 10? In Linux, I would do 'dd', but it has to be Windows. 'dd' is available in Git for Windows, Windows Subsystem for Linux, BusyBox for Windows, and Ubuntu in Hyper-V VM. But, I can't get them to access USB drive. -- William Park <opengeometry@yahoo.ca>
