There are some circumstances in which you may want to take your Windows installation with you, and nothing is more practical than carrying it on a USB thumb drive. WinToUSB can help you boot your system right from an external storage device. It is a pity that the program’s graphical user interface is not attractive or intuitive. In fact, one practically has to decipher the functions of the three large buttons. However, once this initial confusion disappears, the rest of the process becomes much clearer.
The program has three main features. First, you can install Windows to a USB device using an image file as source. Luckily, several image formats are supported, as ISO, WIM, ESD, SWM, VHD and VHDX. Second, you can use an installation disc as well. Last, but in my opinion, most important, the application can make a clone version of the installed system, including all your personalization, folders and files.
In general, WinToUSB is a very useful software tool. There are three different versions of this program, one of them is free and it conveniently allows performing most basic operations. Unfortunately, you should know that, because of reasons inherent to specific operating system versions, Windows 7 may have some portability limitations.
