Im WinUSB, a simple application which helps you create multi-Windows bootable USB drive using any ISO or DVD with Windows 7,8,10 distribution and make it without formatting in most cases! With me you no longer need to transfer many files to hard drive of your PC when you need create Windows bootable USB stick.
I support both UEFI/BIOS for FAT32/NTFS/ExFAT USB flash drives and work same as master and will show you next step after current one completed.
You will need to overcome just three steps:
* Choose USB drive to make bootable
* Choose several distributions on ISO or DVD
* Choose operation system, if you want to format drive initially
