WinUSB, a simple application which helps you burn any Windows 7,8,10 ISO or DVD to USB flash drive and make it bootable without formatting in most cases! With me you no longer need to transfer many files to hard drive of your PC. I work same as master and will show you next step after current one completed.
You will need to overcome just three steps:
Choose ISO or DVD
Choose USB drive
Choose operation system, if you want to format drive initially
Click Go! I'll take care of the rest...
