WinToUSB is intended to install a completely functional copy of Windows on an external storage device. This way, it creates a portable version of your operating system that you can use on other computers, regardless of the operating system installed on their hard disks. Moreover, it can be used to install Windows from a USB memory stick.
The application is very easy to use thanks to a step-by-step wizard, which is accompanied with detailed instructions on what to do. All that is required is to select the target device and the source. In this regard, the tool supports acquiring installation data from both an ISO image and a disc. Likewise, it supports various Windows editions. The portable version can boot from any computer and install the require drivers accordingly. However, it needs an Internet connection to download the necessary data.
All in all, WinToUSB has the main advantage of creating not only a Windows installer but also a portable version of the system. Since it requires transferring a lot of data, it logically takes a while to finish the task.
